Mistake in the registry locked me out

[Guest]

In my effort to clean a trojan, i did by mistake delete a value in the
registry, i believe it is the following:

userinit : C:\windows\system32\userinit.exe

under
HKEY_LOCAL_MACHINE->Software->Microsoft->WindowsNT->CurrentVersion->Winlogon

and this had as an effect that when i login to an account the account log's
off automatically, so i end up in the login screen, without entering the
windows xp enviroment.

Is there a way to fix the registry without logging onto windows?

i've already tried the recovery console(but executes only predefined
commands) and i've tried to boot from some dos disks but the reg.exe file
executes only from the windows xp command line.

Anyone, any idea? Thanks for reading this, and most of all thanks to anyone
who has any suggestion

I'd fix this from a Bart CDR boot, using RunScanner plugin and
Regedit, or by manually binding the HD's hives to HKLM in Regedit.

You prolly don't have Bart, and MS haven't provided that sort of
functionality. This case is an example of why you need such things.
