Windows 10 version 2004 has been the worst updating experience ever! I spent close to two hours fighting reboot loops and hung Windows screens. I had to use the hard power down method multiple times to get the rotating update icon. EVENTUALLY it updated!
Microsoft:
Your support teams suggestions are awful and don't take this scenario into account. Telling a user that a fresh installation is an alternative when all others fail is a major failure on YOUR PART. Consider that it may take many days to reinstall apps that worked on the previous version is ridiculous and cruel. Maybe you should consider having an option to load a USB drive with recovery information so that user can revert back WITHOUT having to try to resuscitate a borked, unresponsive system drive.
SHAME ON YOU!!!!!
