This usually means Windows is signing in with a temporary profile after the update instead of loading the normal profile.
Try these steps in order:
- Check whether Windows reports a temporary profile:
- Go to Start > Settings > Accounts > Sync your settings.
- If the message says You are logged on with a temporary profile. Roaming options are currently unavailable, restart the device and sign in again.
- If the message says We can't sign into your account. This problem can often be fixed by signing out of your account and then signing back in, do that and sign in again.
- Restart more than once if needed:
- It may take more than one restart before the normal profile loads again.
- Back up any files created while in the temporary profile before signing out:
- Copy recent work to an external drive first.
- Those files can be deleted when signing out of the temporary account.
- If files still seem missing after the update:
- Check whether they are in a disabled built-in Administrator account.
- Open Computer Management.
- Go to Local Users and Groups > Users.
- If Administrator shows a down arrow, open its Properties, clear Account is disabled, then select Apply.
- Sign out and sign in with the Administrator account to check whether the files are there.
- If the issue happens during or after Windows Update, run the Windows Update troubleshooter:
- Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
- Find Windows Update and select Run.
- Follow the on-screen steps.
- If updates continue to trigger profile problems, repair system files. This requires administrator permissions:
- Open Command Prompt as administrator.
- Run:
DISM.exe /Online /Cleanup-image /Restorehealth - After it completes successfully, run:
sfc /scannow - Wait for the scan to reach 100%, close Command Prompt, and try Windows Update again.
If the problem continues after these steps, use the Feedback Hub app to report the update issue or contact Microsoft Support.
