Quote from Osayidan;952160:
Windows XP is fully installed and boots up to the login, and when you login you need to activate or it won't work?
Or there isn't even a login yet?
If there's a login you can try to remote access the registry and hope required services are active and firewall lets it pass.
Otherwise try this
Make yourself a BartPE bootable Windows XP disk or ISO: http://www.nu2.nu/pebuilder/
Add this plugin to it: http://regeditpe.sourceforge.net/
boot with it and use it.
Windows XP boots, but immediately asks for the CD to complete installation. Then asks for the key... so no login.
Otherwise try this
I see.
Update:[SPOILER="Spoiler"] Okay I managed to load the hive I needed. It isn't there yet.[/SPOILER] Abort attempt, will find another solution to installing XP.
Thanks for the idea Osay.
