windows 11 update

This behavior matches a damaged user profile, where Windows signs in to a temporary profile and settings reset after each restart.

Try this in order:

1. Open File Explorer and go to C:\Users<original user folder>.
   • Check Desktop, Documents, and other folders to confirm personal files are still there.
   • Copy important files to an external drive first.
   • Do not copy them into the current temporary profile.
2. Create a new local administrator account:
   • Press Windows + R, type netplwiz, and press Enter.
   • Select Add.
   • Choose the option that does not require a Microsoft account.
   • Create a local account.
   • Open that account’s properties, go to Group Membership, and set it to Administrator.
3. Restart the laptop and sign in with the new account.
   • If sign-in works normally and settings persist after restart, the original profile is the problem.
4. Remove the old account:
   • Press Windows + R, type netplwiz, and press Enter.
   • Delete the old account.
   • Restart again.
5. Reconnect the new account to a Microsoft account if needed:
   • Go to Settings > Accounts > Your info.
   • Select Sign in with your Microsoft account.
   • After that, copy files back from the external backup.

If creating a new user does not work, use Windows Recovery:

1. Hold Shift while selecting Restart.
2. Go to Troubleshoot > Advanced options > Uninstall updates.
3. If available, uninstall recent updates one at a time and restart after each.
4. If that does not help, go back to Troubleshoot > Reset this PC.

Also use these Windows 11 checks because the issue started after an update:

1. Start in Safe Mode if normal startup is unstable.
2. Open Device Manager from the Start button menu and look for devices with an ! mark.
   • Update the driver first.
   • If needed, disable or uninstall the affected device.
3. Make sure the system drive has about 10% to 15% free space.
4. Go to Start > Settings > Windows Update and check for newer fixes.

If the PC will not start reliably, in WinRE these are the supported recovery options:

• Uninstall updates if the problem began after a recent Windows update.
• Reset this PC to reinstall Windows, with an option to keep personal files or remove everything.
• Reinstall Windows from recovery media or installation media if reset fails. This can remove everything, so back up files first.
