Windows 10: Unable to update past Windows 10 version 1909, tried everything including wiping my entire...

I recently got out my old PC that I built myself back in 2017. It's old, but it was pretty good back in the day and I wanted to move it into my dorm so that I had a desktop. The only thing is, I started having problems with the new 4k monitor I got, where sometimes when I'd play video games or watch video in full screen the monitor would start losing connection for a few seconds and eventually go green until I manually turned off the computer.I figured that the fact I was years behind on updates was the problem, so I tried updating windows but when it got time to update to version 22H2, everyt

Unable to update past windows version 1909, error "0xc1900204"

As the title says, my computer is refusing to update past version 1909 to version 20H2 or 22H2, I've tried already to use the windows 10 upgrader from: https://www.microsoft.com/en-us/software-download/windows10 however it wont let me keep my files, the options are all greyed out except just wiping the computer. I've tried other solutions from this post:

Update Windows 10 version 1909 to version 21H2

Can I Update Windows 10 version 1909 to version 21H2 (latest)?

Then Please send the useful steps to do that...

By changing windows version 1909 to 21H2 does it removes all files(music, videos, software,etc.) present in my laptop or it is safe, nothing will be deleted.

Now I am not getting critical updates for windows version 1909.

Please anybody give suggestion regarding this matter.

 

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!
