Hi zbook,
Update.
checked drivers etc, as per comment, all ok and updated.
Backup completed a stored in Cloud.
Implemented clean Windows 11 install
Settings, System, Recovery, Reset PC, Remove everything.
Windows 11 download, PC restarted automatically and presented with opening screen,
Entered Microsoft Pin No, access to PC failed, error message: The User Profile Service Failed the sign in.
Tried access with Microsoft Acc No password, same problem and error message, changed password, same problem.
Investigated problem on web, but most theories require access to the command prompt, but I can't get passed the sign-in screen.
Attempted access in SAFE MODE, but same problem.
What is the alternative way of getting a clean install as it appears there is a corruption somewhere?
Thanks
