Solution Steps
- 1 Start by running the System File Checker. Open Command Prompt as administrator and type "sfc /scannow", then press Enter. This checks for corrupted system files and repairs them.
- 2 If SFC doesn't help, run DISM: type "DISM /Online /Cleanup-Image /RestoreHealth" and press Enter. This fixes the Windows image.
- 3 Check for recently installed software that might have caused the issue. Uninstall any suspicious programs via Settings → Apps → Installed apps.
- 4 If the error occurs when accessing a network resource, try reconnecting to the resource. Open File Explorer, right-click on the mapped drive, and select Disconnect. Then reconnect by typing the UNC path.
- 5 If the issue is with a user profile, create a new user account and migrate your files. Go to Settings → Accounts → Family & other users → Add account.
- 6 As a last resort, perform a Windows repair installation using the Windows 11 Installation Assistant, which keeps your files and apps.
