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 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.

Run a SFC on the PC.


If the exe will not run try this article to fix the exe file association

If the MS fixit does not work, go to this page and click the exe box, download the reg file and unzip it, then right click on the reg file and select merge, you may have to unzip it on another pc, then transfer to the problem pc. There is also a fix for "com" on this page.

Association problems can be related to malware, have you scanned the system for malware and viruses lately?

Winhelponline helped. Although I am not sure if the full damage has been recovered. – Jake Feb 23 '11 at 10:36
