I use my Longhorn DVD on Startup and after it loads his sysfiles from DVD I use the recovery options for the momentary installed os ” recovery console ” which means to start the intern CMD to get access to the windows install dir. so I can re-rename the files again to the originals without any trouble =)
( aprox. 4min and I can re-use my installed OS ) hehe
no stress, trouble or second OS =)
