How to fix a Windows 11 computer that is stuck in a restart loop after an update

Summary

This guide helps you troubleshoot and resolve: How to fix a Windows 11 computer that is stuck in a restart loop after an update. Follow the steps below to fix the issue.

Common Causes

If your Windows 11 computer keeps restarting over and over after a recent update, you're stuck in what's commonly called an "update restart loop." This usually happens when an update fails to install correctly, when a driver conflicts with the new build, or when a system file becomes corrupted during the update process. The good news is that this is almost always fixable without losing your data. This guide walks you through the most effective methods to break the loop, starting with the quickest fixes and moving through to more advanced recovery options.

Quick Fix Steps

Before diving into detailed troubleshooting, try these fast solutions first:

• Interrupt the restart cycle — Hold down the power button for 10 seconds to force the computer off, then wait 30 seconds before turning it back on.
• Boot into Safe Mode — If the loop continues, force the computer off three times in a row during the restart process. Windows should automatically boot into the Windows Recovery Environment (WinRE).
• Uninstall the latest update — From WinRE, navigate to Troubleshoot > Advanced options > Uninstall Updates and remove the most recent quality or feature update.

Detailed Instructions

Method 1: Force Boot into Safe Mode

Safe Mode loads Windows with only the essential drivers and services, which lets you remove or roll back the update that's causing the loop.

1. Press and hold the power button for 10 seconds until the computer turns off completely.
2. Wait 30 seconds, then turn the computer back on.
3. As soon as you see the Windows logo (or the spinning dots), hold the power button again to force a shutdown.
4. Repeat steps 2 and 3 two more times. On the third restart, Windows should enter the Automatic Repair screen.
5. Click Advanced options.
6. Select Troubleshoot > Advanced options > Startup Settings > Restart.
7. After the restart, press F5 (or 5) to select Safe Mode with Networking.

Once you're in Safe Mode, proceed to Method 2 to remove the troublesome update.

Method 2: Uninstall the Problematic Update

1. In Safe Mode, press Windows + I to open Settings.
2. Navigate to Windows Update > Update history.
3. Scroll down and click Uninstall updates.
4. You'll see two options: Uninstall latest feature update and Uninstall latest quality update.
5. Start with the quality update (these are the smaller monthly patches and are the most common cause of restart loops). Click Uninstall and confirm.
6. If the loop started after a major version upgrade (such as moving from 23H2 to 24H2), uninstall the feature update instead.
7. Restart your computer normally and check whether the loop has stopped.

Method 3: Use System Restore

If uninstalling the update doesn't work, or you can't reach Safe Mode, System Restore can roll your computer back to a point before the update was installed.

1. From the WinRE screen (reached by force-shutting down three times), select Advanced options.
2. Choose Troubleshoot > Advanced options > System Restore.
3. Select your Windows installation (usually Windows 11) and click Next.
4. Pick a restore point dated before the update that caused the loop. If you don't see one, make sure Show more restore points is ticked.
5. Click Next > Finish, then confirm to start the restore.
6. Your computer will restart and roll back to the selected restore point.

Method 4: Run Startup Repair and System File Checks

Corrupted system files can keep Windows stuck in a restart loop even after an update is removed. These built-in tools can repair them.

1. From WinRE, go to Troubleshoot > Advanced options.
2. Select Startup Repair and let Windows attempt to fix boot issues automatically.
3. If Startup Repair doesn't resolve the issue, return to Advanced options and choose Command Prompt.
4. Run the following commands in order, pressing Enter after each:
   
   sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
5. Wait for both scans to complete. SFC checks for and repairs corrupted system files, while DISM repairs the underlying component store.
6. Type exit and restart your computer.

Method 5: Roll Back or Disable a Faulty Driver

A driver installed alongside the update is sometimes the real culprit, particularly graphics, network, or chipset drivers.

1. Boot into Safe Mode with Networking (see Method 1).
2. Right-click the Start button and select Device Manager.
3. Look for any device with a yellow triangle warning icon.
4. Right-click the device, choose Properties, then click the Driver tab.
5. If a Roll Back Driver button is available, click it and follow the prompts.
6. If roll back isn't available, click Uninstall Device, tick Attempt to remove the driver for this device, and confirm.
7. Restart your computer. Windows will attempt to install a generic driver, which should break the loop.

Method 6: Reset Windows While Keeping Your Files

If none of the above methods work, a Windows reset will reinstall the operating system while preserving your personal files. Use this as a last resort before a full reinstall.

1. From WinRE, select Troubleshoot > Reset this PC.
2. Choose Keep my files.
3. Select Cloud download (downloads a fresh copy of Windows from Microsoft) or Local reinstall (uses files already on your computer). Cloud download is generally more reliable.
4. Click Change settings and confirm that Restore preinstalled apps is set to No unless you want manufacturer bloatware reinstalled.
5. Click Next, then Reset.
6. The process takes 20–60 minutes. Your files in C:\Users will be preserved, but apps and settings will be removed.

Method 7: Perform a Clean Install of Windows 11

If a reset also fails, a clean install is the final option. This erases everything on the drive and installs a fresh copy of Windows 11.

1. On another working computer, visit the Microsoft Software Download page and use the Media Creation Tool to create a bootable USB drive (at least 8 GB).
2. Back up all important files to an external drive or cloud storage.
3. Insert the USB drive into the affected computer and boot from it (you may need to change the boot order in the BIOS/UEFI settings, usually by pressing F2, F12, or Del during startup).
4. When prompted, choose Custom: Install Windows only.
5. Select the partition where Windows is installed and click Format (this erases all data on that partition).
6. Follow the prompts to complete the installation.
7. Once Windows is installed, visit your computer manufacturer's website to download the latest drivers, and reinstall your applications.

Preventing Future Restart Loops

Once your computer is running normally again, a few habits can reduce the chance of this happening in future:

• Pause updates for a week or two after major Patch Tuesday releases to let early issues be reported and fixed.
• Create a restore point manually before installing major updates: search for Create a restore point in the Start menu and click Create.
• Keep drivers up to date through your manufacturer's website rather than relying solely on Windows Update.
• Back up regularly using File History, OneDrive, or a third-party backup tool so you always have a recent copy of your files.
