After log in computer imediately log us out again and turn us back to log in page.

We was wrong, we installed the PE Builder on our Win7 machine and created a boot CD for WinXP Pro SP2.
But we could never access the Registry with Bart’s PE.
So we downloaded Hiren’s BootCD 10.4
http://www.hirensbootcd.net/ and used the Registry editor there.
We did the following in the registry:
Changed the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon" from "C:\windows\system32\system32.exe"
à "C:\WINDOWS\system32\userinit.exe,"
We rebooted and the computer started as normal J
Thank’s Lain A to pointing us to the right direction.
It took some time but now we are up and running again.
We se that you have a medal, you are worth it.
Thank’s again.
