Windows Whistler 2428 login error

[WindowsMan 0]

Can anyone help. When i type my password to log in to whistler build 2428, i get an error as follows:

 

Windows product activation

something like a file cannot be loaded. Please run setup again. I did this twice but the error still occurs. The error states a .dll file of some sort

This happens with both administrator and guest login.

 

What can i do, ive tried upgrades and clean installs and they both went fine. Thanks in advance

boot in safe mode, run regedit, and find this entry: HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WindowsNT\CurrentVersion\Winlogon\Activation Required

 

Change it from 1 to 0
