Windows 10: Windows 10 update rolled back user profile

Hi.I've a curious situation that I've not encountered before and cannot find any reference to via my usually reliable resources.One of my clients reports he was prompted to run a Windows update when shutting down his W10Pro workstation last night Oct 20, 2021.This morning they logged on and found that their system appeared to have rolled back to a point in the past, guessing about 6 months ago.All credentials had been removed and I had to reconfigure his emails in Outlook.Looking at the Windows update history, there was no evidence of any updates being run yesterday. The last update installed

User.000 issue after updating to 1909

I'm one of the many people suffering from issues with user profiles after applying Update 1909 to Windows 10. I've read all the threads I can find on the topic here and have followed the suggestions, all to no avail. Any other thoughts are appreciated.

After applying Update 1909, the ProfileImagePath was changed to c:\users\User.000
One file that was always in use and couldn't be removed was left in c:\users\User (can't recall or find the exact file now), so I could never rename or remove the c:\user\User directory.

I followed the multiple suggestions from Brink and others:

• Rebooted at least 6 times
• Enabled hidden Administrator
• Booted into Safe Mode
• Changed ProfileImagePath
• Tried to rename c:\users\User but couldn't because a file was still in use
• Copied all data from c:\users\User.000 into c:\users\User
• Rebooted and had temporary profile
• Followed steps in Brink tutorial to change ImageProfilePath; rebooted with no change
• Restored using Restore Point from before Update 1909 - returned to single profile state (User.000)
• Removed each update that was installed individually and rebooted after each update removal - profile state never changed
• After all updates were removed, repeated the steps above with hidden Administrator, changing profile, etc. - same issue with file in use in c:\users\User
• Followed all steps above with hidden Administrator but without copying files from User.000 to User - same results

Any suggestions are greatly appreciated!
