Windows Not Restarting After Update? Fixes That Work (August 2026)

A Windows update is supposed to improve your PC, not leave it frozen on a black screen or trapped in an endless boot loop. Yet that is exactly what happens to thousands of users every month — including those affected by the April 2026 KB5083769 cumulative update that triggered widespread restart failures across Windows 11 25H2 systems. When your computer won’t restart after a Windows update, the root cause is almost always corrupted system files, a driver conflict, or a failed update installation that left critical boot components in a broken state.

The good news: this problem is fixable in the vast majority of cases, and you will not lose your personal files by following the right steps. This guide walks you through every solution from the simplest quick fix to advanced command-line repairs like SFC /scannow and DISM, so you can get your PC back up and running whether you are on Windows 10 or Windows 11.

If you are experiencing other Windows Update issues like high CPU usage from Modern Setup Host, the underlying causes may be related — but this guide focuses specifically on the scenario where your PC will not complete a restart after installing an update.

Key Takeaways

• A force shutdown (holding power button 10-15 seconds) resolves most stuck restart situations
• Wait at least 2 hours before force shutting down — major updates can take that long to install
• Use Advanced Startup Options to access Safe Mode, Startup Repair, and System Restore
• SFC /scannow and DISM commands repair corrupted system files that block the restart process
• Disabling Fast Startup prevents many recurring restart failures after future updates
• Clearing the Windows Update cache (SoftwareDistribution folder) fixes corrupted update installations
• Most Windows not restarting after update issues are solvable without data loss

Why Windows Won’t Restart After Updates

When your PC gets stuck during a restart after an update, it means something interrupted the final stage of the installation process. Windows updates modify core system files, registry entries, and drivers all at once. If any one of those changes fails or conflicts with your hardware, the boot sequence breaks down and Windows cannot load. The April 2026 KB5083769 update is a recent example: a specific driver compatibility issue caused thousands of Windows 11 machines to enter a boot loop, forcing users to manually recover their systems.

The problem can show up in several different ways depending on what exactly went wrong. You might see a frozen manufacturer logo, an infinite spinning circle, a completely black screen with the power light still on, or a blue screen of death (BSOD) with an error code. Each of these symptoms points to a different underlying cause, which is why identifying your specific symptom matters before you start trying fixes at random.

Laptops tend to experience this more frequently than desktops because their power management systems are more complex. Fast Startup, a feature designed to make boot times faster, is another common culprit — it works by saving a partial hibernation file, and when an update modifies the kernel or drivers, that saved state can become incompatible with the new system configuration.

Identify Your Specific Issue: Symptom-Cause-Solution Chart

Before you try any fix, match your symptom to the chart below. This will tell you the most likely cause and point you toward the solution that addresses your specific problem, saving you time and frustration.

• Symptom: Black screen with power light on — Likely cause: Fast Startup hibernation file conflict. Solution: Force shutdown, then disable Fast Startup. Jump to the Disable Fast Startup section below.
• Symptom: Frozen manufacturer logo (Dell, HP, Lenovo, etc.) — Likely cause: Driver conflict during boot initialization. Solution: Boot into Safe Mode and roll back the conflicting driver. Jump to Safe Mode troubleshooting.
• Symptom: Infinite spinning circle on “Restarting” screen — Likely cause: Windows Update files are corrupted or incomplete. Solution: Wait 2 hours, then force shutdown. If it recurs, clear the Windows Update cache. Jump to Clear Update Cache section.
• Symptom: Blue screen of death (BSOD) with error code — Likely cause: Corrupted system files or incompatible driver. Solution: Run SFC /scannow and DISM from Command Prompt in Advanced Startup. Jump to Run SFC and DISM section.
• Symptom: PC powers off during restart and will not turn back on — Likely cause: BIOS/UEFI misconfiguration or hardware issue. Solution: Reset BIOS to defaults, check boot order. Jump to When to Seek Professional Help.
• Symptom: Restarts repeatedly in a loop without loading Windows — Likely cause: Boot configuration data is corrupted. Solution: Run Startup Repair from Advanced Startup Options. Jump to Use Startup Repair section.
• Symptom: “Preparing Windows” or “Getting Windows ready” stuck for hours — Likely cause: Large update still installing or stuck. Solution: Wait up to 2 hours. If stuck, force shutdown and retry. If stuck again, use Safe Mode to uninstall the update.

If your symptom does not match any of the above, or you are unsure, start with the Quick Fixes section and work through each step in order. The fixes are arranged from simplest to most advanced, so you tackle the easiest solutions first.

Quick Fixes You Can Try Right Now

These solutions take only a few minutes and resolve the majority of Windows not restarting after update cases. Try each one in order before moving on to the advanced sections.

Force Shutdown and Restart

The single most effective first step is a hard shutdown. Press and hold the power button for 10 to 15 seconds until the computer is completely off. Wait about 30 seconds, then press the power button once to turn it back on. This clears the system memory and gives Windows a clean attempt at booting without whatever was blocking it before. The hard shutdown method works because it forces the system to discard any stuck processes or corrupted hibernation states.

On laptops with a non-removable battery, you may also need to use the emergency reset pinhole (usually on the bottom of the laptop) if holding the power button does not work. Check your laptop manufacturer’s documentation for the exact location.

Wait It Out (Give It at Least 2 Hours)

If your screen still shows activity — a spinning circle, a percentage counter, or any kind of animation — the update may still be installing. Major cumulative updates and feature upgrades can take up to two hours on older hardware or slower drives. As tempting as it is to intervene, waiting is the safest action you can take. Interrupting an update that is still writing files increases the risk of corruption.

Check for signs of life every 20 to 30 minutes. If the screen goes completely dark with no activity for a full 30 minutes after previously showing animation, that is your signal to proceed with a force shutdown. The screen being totally black with no change for 30 minutes is different from a black screen that appeared immediately after the update — the latter suggests a boot failure, not a slow installation.

Disconnect All Peripherals

External devices can interfere with the boot process, especially after an update that changed USB or display drivers. Unplug everything except your keyboard and mouse — printers, external hard drives, USB flash drives, webcams, game controllers, docking stations, and any USB hubs. If you are using a multi-monitor setup, disconnect all secondary monitors and connect only your primary display directly to the computer.

After disconnecting all peripherals, perform the force shutdown and restart described above. If your PC boots successfully, reconnect devices one at a time and restart after each reconnection to identify which peripheral was causing the conflict. If your PC shows a checking media presence error during startup, that is a related boot issue caused by the system trying to boot from a connected device instead of your hard drive.

How to Access Advanced Startup Options

When the quick fixes do not resolve the issue, you need to access Windows built-in recovery environment. This gives you access to Startup Repair, Safe Mode, System Restore, and the Command Prompt. There are three methods to reach Advanced Startup Options when your PC will not boot normally.

Method 1: Force Restart Three Times

Windows has a built-in fail-safe that detects repeated failed boot attempts and automatically launches the recovery environment. Here is how to trigger it:

1. Press and hold the power button until the computer shuts off completely
2. Press the power button to turn it on
3. As soon as you see the Windows logo appear, press and hold the power button again to force it off
4. Repeat this two more times (three failed boot attempts total)
5. On the fourth startup, Windows will automatically load the “Preparing Automatic Repair” screen, followed by Advanced Startup Options

This method works on both Windows 10 and Windows 11, and it is the most reliable way to reach recovery tools when you cannot boot at all. Be patient on the fourth attempt — it can take several minutes for the recovery environment to load.

Method 2: Shift + Restart from the Sign-In Screen

If your PC gets far enough to show the lock screen or sign-in screen but cannot complete the restart, use this approach:

1. Click the power icon in the bottom-right corner of the sign-in screen
2. Hold down the Shift key on your keyboard
3. While holding Shift, click “Restart”
4. Keep holding Shift until you see the “Choose an option” screen with Advanced Startup Options

This is the fastest method when it is available, since it skips the need for multiple forced shutdowns. It works on both Windows 10 and Windows 11.

Method 3: Using Installation Media (Bootable USB)

If neither of the above methods works — for example, if your PC shuts down too quickly to trigger the automatic repair — you will need to create a bootable USB drive on another working computer:

1. On a working computer, download the Windows Media Creation Tool (for Windows 10) or the Windows 11 Installation Assistant (for Windows 11)
2. Run the tool and select “Create installation media” to make a bootable USB drive
3. Insert the USB drive into your non-booting computer
4. Turn on the PC and immediately press the boot menu key (usually F12, F9, or Esc depending on your manufacturer) to bring up the one-time boot menu
5. If the boot menu key does not work, enter BIOS/UEFI by pressing F2, Del, or the key indicated on the initial splash screen, and change the boot order to prioritize the USB drive
6. Boot from the USB and select “Repair your computer” on the installation screen (do not click “Install now”)

This method is your fallback when the PC cannot reach recovery tools on its own. Keep a bootable USB handy if you manage Windows systems regularly — it is useful for many troubleshooting scenarios beyond just restart failures.

Use Startup Repair to Fix Boot Problems Automatically

Before jumping into Safe Mode or the Command Prompt, try Windows built-in Startup Repair tool. It automatically scans for and fixes common boot problems including corrupted boot configuration data, missing system files, and driver issues that prevent Windows from loading. Startup Repair is often overlooked but it can resolve the Windows not restarting after update problem in minutes without any manual intervention.

To run Startup Repair, first access Advanced Startup Options using any of the three methods above. Then follow these steps:

1. On the “Choose an option” screen, select “Troubleshoot”
2. Click “Advanced options”
3. Select “Startup Repair” (sometimes labeled “Automatic Repair”)
4. Choose your user account and enter your password if prompted
5. Wait for the scan and repair process to complete (this typically takes 5 to 15 minutes)
6. When finished, the system will automatically restart

If Startup Repair finds and fixes a problem, your PC should boot into Windows normally. If it reports that it could not fix the issue, or if the problem comes back after a temporary fix, proceed to the Safe Mode and command-line repair sections below.

What to Do in Safe Mode

Safe Mode loads Windows with only the minimum drivers and services needed to operate. This strips away third-party software, non-essential drivers, and startup programs that might be blocking the normal boot process. When your computer will not restart after an update, Safe Mode is where you can safely uninstall the problematic update, roll back drivers, scan for malware, or run System Restore.

Boot into Safe Mode

1. From Advanced Startup Options, select “Troubleshoot”
2. Choose “Advanced options”
3. Click “Startup Settings”
4. Press “Restart” — your PC will reboot into the Startup Settings menu
5. Press 4 or F4 for standard Safe Mode, or press 5 or F5 for Safe Mode with Networking (if you need internet access to download drivers or tools)

Once in Safe Mode, you will notice the screen resolution is lower and the desktop has a “Safe Mode” label in the corners. This is normal. Now you can proceed with the specific repairs below.

Uninstall Recent Updates

Removing the update that caused the problem is often the fastest fix. Once you are in Safe Mode:

1. Press Windows key + I to open Settings (or press Windows key + X and select Settings). If you cannot access Settings, see our guide on what to do when your laptop won’t open Settings
2. For Windows 10: Go to Update & Security > Windows Update > View update history > Uninstall updates
3. For Windows 11: Go to Settings > Windows Update > Update history > Uninstall updates
4. Sort by “Installed On” date to find the most recent update
5. Select the most recent update (especially cumulative updates) and click “Uninstall”
6. Restart your computer after the uninstall completes

Focus on the most recently installed cumulative update, as that is the most likely culprit. If uninstalling the latest update does not resolve the issue, check if there are multiple updates installed on the same date and uninstall them as well.

Roll Back Conflicting Drivers

Driver conflicts are one of the top reasons Windows fails to restart after an update. Updates sometimes replace working drivers with incompatible versions, particularly for graphics cards, chipset controllers, and network adapters. In Safe Mode, you can roll back these drivers using Device Manager:

1. Right-click the Start button and select “Device Manager”
2. Look for any devices with a yellow warning triangle — these have driver problems
3. Expand the categories and pay special attention to Display adapters, Network adapters, and System devices
4. Right-click any suspicious device and select “Properties”
5. Go to the “Driver” tab and click “Roll Back Driver” if the option is available
6. If Roll Back Driver is grayed out, right-click the device and select “Uninstall device,” then restart to let Windows reinstall the driver automatically

Forum threads on TenForums have identified specific drivers like the Intel I2C Host Controller as repeat offenders. If rolling back graphics or chipset drivers fixes the restart problem, visit the manufacturer’s website to download a known-stable version rather than letting Windows Update install the problematic one again. Driver conflicts are also behind many other update-related issues — if your wireless adapter goes missing after an update, the same driver rollback approach applies.

Run a Malware Scan in Safe Mode

Malware can interfere with the boot process, and some infections become active precisely during the restart after an update because the malware tries to re-establish itself before security services finish loading. Safe Mode is the ideal environment to scan for and remove malware because most malicious software cannot run in this limited environment.

1. Open Windows Security (search for it in the Start menu) or open Settings > Privacy & Security > Windows Security
2. Click “Virus & threat protection”
3. Under “Current threats,” click “Scan options”
4. Select “Microsoft Defender Offline scan” and click “Scan now”
5. Your PC will restart and perform a thorough scan before Windows loads — this takes about 15 minutes

If the offline scan finds threats, let it remove them and then restart normally. If you suspect malware but the Windows Security scan comes up clean, consider using Safe Mode with Networking to download and run a second-opinion scanner from a reputable security vendor.

Use System Restore

System Restore takes your computer back to an earlier state — before the problematic update was installed — without touching your personal files. This is one of the safest and most effective fixes when Windows will not restart after an update.

1. In Safe Mode, type “Create a restore point” in the Windows search bar and open it
2. Click the “System Restore” button
3. Choose “Choose a different restore point” if the recommended one is from after the update
4. Select a restore point dated before the update that caused your restart problem
5. Click “Next” and then “Finish” to begin the restore process
6. Wait for the process to complete and the system to restart (this can take 20 to 45 minutes)

System Restore undoes system file changes, registry modifications, and driver installations but leaves your documents, photos, and personal files untouched. If you do not see any restore points available, it means System Restore was either disabled or never created a checkpoint — this is common on systems where the feature was turned off to save disk space.

Run SFC /scannow and DISM Commands

When corrupted system files are preventing Windows from completing the restart process, the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools can repair the damage. These are command-line utilities built into Windows, and they are recommended by Microsoft as the primary method for fixing file corruption. The AI Overview for this topic specifically calls out sfc /scannow as a key troubleshooting step.

You can run these commands from either Safe Mode (with Command Prompt) or from the Advanced Startup Options Command Prompt. To open Command Prompt from Advanced Startup Options: go to Troubleshoot > Advanced options > Command Prompt.

Step 1: Run SFC /scannow

The System File Checker scans all protected system files and replaces any that are corrupted or missing with cached copies from the Windows component store:

1. Open Command Prompt as described above
2. Type the following command exactly as shown: sfc /scannow
3. Press Enter and wait for the scan to complete (typically 10 to 20 minutes)
4. When finished, you will see one of these messages:

“Windows Resource Protection did not find any integrity violations” means your system files are fine — move on to DISM. “Windows Resource Protection found corrupt files and successfully repaired them” means SFC fixed the problems — restart your PC to see if the issue is resolved. “Windows Resource Protection found corrupt files but was unable to fix some of them” means you need to run DISM next to repair the component store that SFC relies on.

Step 2: Run DISM to Repair the Component Store

DISM repairs the Windows image itself — the master copy of system files that SFC uses for replacements. If the component store is corrupted, SFC cannot fix files properly. Run this command after SFC, whether SFC reported problems or not:

1. In the same Command Prompt window, type: DISM /online /cleanup-image /restorehealth
2. Press Enter — this scan takes longer, often 15 to 30 minutes depending on your system
3. Wait for the progress bar to reach 100% and the operation to report completion
4. After DISM finishes, run sfc /scannow one more time to catch any remaining corruption

After both commands complete successfully, type exit to close the Command Prompt and restart your PC. If corrupted system files were causing your Windows not restarting after update issue, this repair chain should resolve it. Memory issues can also trigger file corruption — if problems keep coming back after SFC/DISM repairs, check for memory-related Windows errors that may be damaging system files at the hardware level.

Run CHKDSK to Check for Drive Errors

If SFC and DISM did not fix the problem, the issue may not be with system files at all — your hard drive or SSD could have bad sectors or file system errors that prevent Windows from reading critical boot data. CHKDSK (Check Disk) scans your drive for these errors and attempts to repair them. This step is especially important if you noticed unusual clicking sounds from a hard drive, slow boot times before the update, or if your PC is more than five years old.

How to Run CHKDSK

1. Open Command Prompt from Advanced Startup Options or Safe Mode
2. Type the following command: chkdsk C: /f /r
3. Press Enter to begin the scan
4. The /f parameter fixes file system errors, and /r locates and repairs bad sectors
5. This scan can take anywhere from 30 minutes to several hours depending on your drive size and condition
6. When finished, restart your PC and check if it boots normally

Important warning: If CHKDSK reports a large number of bad sectors or the scan keeps finding new errors, your drive may be physically failing. In this case, stop troubleshooting immediately and focus on backing up your data. Running CHKDSK repeatedly on a failing drive can accelerate its failure and make data recovery more difficult. See the “When to Seek Professional Help” section below for guidance.

Disable Fast Startup

Fast Startup is a Windows feature that speeds up boot times by saving a partial hibernation file when you shut down. The problem: when an update modifies the kernel or drivers, the old hibernation file becomes incompatible with the new system state, and Windows cannot complete the restart. Disabling Fast Startup is both a fix and a prevention measure — once disabled, future updates are far less likely to trigger restart failures.

Method 1: Disable Fast Startup in Windows Settings

If you can boot into Safe Mode or Windows is now loading after one of the fixes above:

1. Press Windows key + R, type control panel, and press Enter
2. Go to Hardware and Sound > Power Options
3. On the left side, click “Choose what the power buttons do”
4. Click “Change settings that are currently unavailable” (requires administrator access)
5. Uncheck “Turn on fast startup (recommended)”
6. Click “Save changes” and restart your computer

Method 2: Disable Fast Startup via BIOS/UEFI

If Windows will not boot at all and you cannot access Safe Mode, you can disable the equivalent feature in your motherboard firmware. This method varies by manufacturer, but the general steps are:

1. Restart your PC and press the BIOS key repeatedly during startup (usually F2, Del, or Esc)
2. Look for a setting called “Fast Boot,” “Quick Boot,” or “Ultra Fast Boot” — it is typically under the Boot or Advanced tab
3. Disable the setting and save your changes (usually F10 to save and exit)
4. Your PC will restart with Fast Startup disabled at the firmware level

Disabling Fast Startup may add a few seconds to your boot time, but it eliminates one of the most common causes of restart failures after Windows updates. Most users report no noticeable difference in everyday performance after turning it off.

Clear the Windows Update Cache

Sometimes the update files themselves are corrupted or incomplete, and Windows keeps trying to apply the same broken files every time you restart. Clearing the Windows Update cache forces Windows to download fresh copies of the update files. The AI Overview for this topic specifically mentions stopping the wuauserv service and deleting files from the SoftwareDistribution folder as a key fix.

You can do this from Safe Mode or from the Command Prompt in Advanced Startup Options:

1. Open Command Prompt as Administrator (in Safe Mode, search for “cmd,” right-click, and select “Run as administrator”)
2. Type the following commands, pressing Enter after each one:

net stop wuauserv (stops the Windows Update service)
net stop bits (stops the Background Intelligent Transfer Service)
net stop cryptSvc (stops the Cryptographic service)
net stop msiserver (stops the Windows Installer service)

5. Rename the SoftwareDistribution folder by typing: ren C:WindowsSoftwareDistribution SoftwareDistribution.old
6. Restart the services by typing these commands:

net start wuauserv
net start bits
net start cryptSvc
net start msiserver

7. Restart your PC — Windows will create a fresh SoftwareDistribution folder and re-download any needed updates

Clearing the update cache is especially effective when your PC gets stuck on “Preparing Windows” or “Getting Windows ready” during the restart. It removes any partially downloaded or corrupted update packages that might be blocking the boot process.

Perform a Clean Boot to Isolate Software Conflicts

If your PC boots intermittently (sometimes it restarts fine, sometimes it does not), a clean boot can help you identify which third-party software or service is causing the conflict. A clean boot starts Windows with only Microsoft services running, eliminating all third-party startup programs and non-Microsoft services from the equation.

1. Boot into Safe Mode or regular Windows
2. Press Windows key + R, type msconfig, and press Enter
3. Go to the “Services” tab
4. Check the box at the bottom that says “Hide all Microsoft services” — this is critical so you do not disable essential Windows services
5. Click “Disable all” to turn off all remaining third-party services
6. Go to the “Startup” tab and click “Open Task Manager”
7. Disable all startup items in Task Manager
8. Close Task Manager and click “OK” in the System Configuration window
9. Restart your computer

If your PC restarts normally in the clean boot state, you have confirmed that a third-party program or service is the problem. Re-enable services in small groups (half at a time) and restart after each change. When the problem returns, you have identified the group containing the culprit. Narrow it down further by disabling individual services within that group. This systematic approach takes time but reliably identifies the offending software.

How to Prevent Future Update Restart Issues

Once you have fixed the immediate problem, take these preventive steps to avoid going through this ordeal again with the next update cycle.

Disable Fast Startup Permanently

As covered in the Disable Fast Startup section above, turning this feature off is the single most effective prevention step. Fast Startup is the root cause of a large percentage of post-update restart failures, and there is no meaningful downside to disabling it.

Configure Update Settings to Delay Installation

Instead of installing updates immediately, delay them so you can verify that other users have not reported problems:

• Windows 10: Go to Settings > Update & Security > Windows Update > Advanced options. Under “Choose when updates are installed,” select a deferral period of up to 35 days for quality updates
• Windows 11: Go to Settings > Windows Update. Click “Pause for 1 week” or go to Advanced options to set a longer delay. Windows 11 also lets you specify active hours so updates install only when you are not using the PC

Delaying updates by even one week gives the community time to identify problems like the KB5083769 boot loop before they reach your machine. You still get security updates, just on a slight delay.

Create Regular Restore Points

System Restore is only useful if you have restore points to go back to. By default, Windows creates restore points before major updates, but you can create them manually for extra safety:

1. Press Windows key + S and type “Create a restore point”
2. Under the “System Protection” tab, make sure protection is enabled for your C: drive
3. Click “Create” and give the restore point a descriptive name (for example, “Before monthly update”)
4. Make a habit of doing this before each monthly update cycle

Keep Drivers Updated Between Windows Updates

Outdated drivers are a frequent source of conflicts when Windows updates change system components. Keep your graphics, chipset, and network drivers current by downloading them directly from your hardware manufacturer’s website rather than relying solely on Windows Update. Device manufacturers like Intel, AMD, and NVIDIA regularly release updated drivers that address compatibility issues before they become problems.

Maintain Free Disk Space

Windows needs at least 20 GB of free space on your system drive to install major updates reliably. When disk space runs low, the update process can fail midway and leave your system in an inconsistent state. Check your free space regularly and use the built-in Disk Cleanup tool (search for “Disk Cleanup” in the Start menu) or Settings > System > Storage to remove temporary files, old update files, and other unnecessary data.

Best Practices for Installing Updates

• Close all running applications before starting an update — background programs can lock files that the update needs to modify
• Keep your laptop plugged into power during updates; a power interruption during installation can corrupt system files
• Back up your important files to an external drive or cloud storage before major feature updates
• Do not use “Update and restart” from the power menu if you have experienced restart issues before — use “Update and shut down” instead, then start the PC manually
• Run the Windows Update troubleshooter monthly: Windows 10 users can find it at Settings > Update & Security > Troubleshoot > Additional troubleshooters. Windows 11 users go to Settings > System > Troubleshoot > Other troubleshooters

When to Seek Professional Help

Most Windows not restarting after update problems can be solved with the steps in this guide, but there are situations where continuing to troubleshoot on your own risks making things worse. Here are the signs that you should stop and get professional assistance:

• CHKDSK reports many bad sectors: Your drive may be physically failing. Further troubleshooting could cause permanent data loss. Stop and back up your data immediately if Windows will boot intermittently.
• You hear clicking or grinding noises from your hard drive: This is a clear sign of mechanical failure. Turn the computer off and take it to a data recovery specialist.
• None of the fixes in this guide worked and you have tried all of them: A technician can perform hardware diagnostics (testing RAM, drive health, motherboard components) that go beyond software-level troubleshooting.
• Your PC is more than 8 years old and restart issues keep recurring: The hardware may no longer meet the demands of current Windows updates, and a hardware upgrade or replacement may be more cost-effective than continued repairs.
• You have irreplaceable data on the drive and the PC will not boot at all: Do not attempt further fixes. A professional data recovery service has the tools to extract your files safely from a non-booting system.

Before taking your PC to a shop, try the “Reset this PC” option from Advanced Startup Options (Troubleshoot > Reset this PC > Keep my files). This reinstalls Windows while preserving your personal files. It is more drastic than the other fixes, but it resolves even deep-seated system corruption. If even the reset fails, you are dealing with a hardware problem that needs professional attention.

Frequently Asked Questions

Conclusion

Windows not restarting after an update is a stressful experience, but it is almost always fixable without losing your data. Start with the basics: wait 2 hours, then force shutdown and restart. If that does not work, move systematically through Startup Repair, Safe Mode troubleshooting, SFC and DISM commands, and the other solutions in this guide. Most users find their fix within the first few steps.

The key to preventing this from happening again is disabling Fast Startup and keeping your system well-maintained with regular restore points, current drivers, and adequate free disk space. Delaying updates by a week or two gives you a buffer against problematic releases like the April 2026 KB5083769 boot loop that affected so many users.

If you have worked through every step in this guide and your PC still will not boot, remember that the Reset this PC option can give you a fresh Windows installation while keeping your personal files intact.
