Step 1 – Press windows key + r on your computer. In the run box type regedit and click ok.





Step 2 – In the registry editor which appears browse to the following path given below from the left menu.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList




Step 3 – Now, in the ProfileList find keys having this combination s-1-15-21-some_long_numbered_key_here

For example, the entry indicated with arrow in the above screenshot is having this type of format.

Note – Now, in the screenshot given above i only have one this type of long keyed entry in the profile list. That is because i only have one user account in my system. For users having 3 user accounts there will be 3 such entry.

But, users experiencing this update error will be having more entries than the users accounts.

In the right pane double click on the ProfileImagePath and check the value data. It will say something like C:\Users\the_user_account_name_here




If its not matching the user account name in your system, delete the entry by doing a right click and delete in left menu pane in the registry editor.
