Updates

Lately my updates are failing, all of them, done a ton of stuff but nothing really helps, but today I came across this:
Open REGEDIT.EXE, navigate to,
HKEY_USERS\.DEFAULT\Software/Microsoft\Windows\ CurentVersion\Explorer\User Shell Folders
The correct value is %APPDATA%
Right click on AppData, choose modify, Change this to %USERPROFILE%\APPDATA\ROAMING.

at this point all is well for me, updates are working again, but there was more

If the problem persists continue with
Open REGEDIT.EXE, navigate to,
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurentVersion\Explorer\user Shell Folders
The correct value is %APPDATA%
Right click on AppData, choose modify, Change this to %USERPROFILE%\AppData\Roaming

And Change
HKEY_LOCAL_MACHINES\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
The correct value is %APPDATA%
Right click on AppData, choose modify, Change this to %USERPROFILE%\AppData\Roaming

then I came across this, an automatic fix from MSFT,

I included the manual fix and the auto because I don't know if the auto works, but I know the manual does
