I have a Windows 7 laptop with the user "mydomain\boy" that cannot log in to the laptop. The error message is something like "User profile service cannot log in the user boy".
I then logged in with the domain admin account "mydomain\admin" and went to delete the "mydomain\boy" from
My Computer > System Properties > Advanced system settings > User Profiles > Settings.
I also ensured that the user was deleted from
Control Panel > User Accounts.
I then deleted the user's folder C:\Users\boy and checked the registry at the location
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\ to make sure that there was no entry for boy.
I followed http://support.microsoft.com/kb/947215 using method 3 "Fix it for me" but does not seem to do anything (or I don't know how to use it).
After everything above... Every time I log in with a new user, be it boy, girl or any other domain account (other than the admin account already created when I first logged in to begin the fix/break), it takes a long time, and when the "preparing desktop" goes away, it starts to show Cannot open xyz.exe errors, e.g., regsvr.exe because of a file association problem with the .exe extension.
My question (*phew* finally...): Please tell me how to fix this? Thanks!
EDIT: Also cannot run .com files.
