User profile can not load in windows 7

If you have problem at login with windows 7, and windows 7 show message "user failed login" or other. I think u must try this tips :

To resolved this problem you must login with another user, for example administrator, if you are login please follow the step :

1. Please select button Start > Run > and type " regedit ". If you confused you can see the article in my blog changing the content of the registry
2. In regedit menu please select HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > Profilelist

3. In the Profilelist if you can see the key folder with the .bak like below :

4. Please rename the key folder with the .bak to .bk
5. Close the regedit and log off computer. now you can try login the user had, Windows 7 will create the new profile for your user.

If you have problem please contact me....
Thank you.
