How to install Windows Updates automatically or manually?

Question

How to install Windows Updates? There is always the same error code when I attempt an update (error 646).

Answer 1

Error 646 is directly related to the AppData folder that is improperly defined in the registry database of your computer. Microsoft was aware of this problem and issued a fix for it.

Go to Start > Run and type regedit then navigate to the following key:

• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\

The AppData path should look like: %USERPROFILE%\AppData\Roaming

Double click to change it and then perform another update attempt. If the error persists repeat the same procedure for the following keys in the registry editor:

• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\

• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\

After there fixes, everything should be back to normal.
