i had a failed SP1 install...

now im stuck with the system trying (and failing) to finilize instalation @boot,

the system after log-in thinks its SP1

SP1 uninstaller says it cant uninstall

SP1 installer says allready installed

SP2 installer says install SP1

is there a way to remove SP1 information, fool the system to think it doesnt have service pack and install it again ?

i REALLY dont want to reinstall windows. that would suck so badly that id rather stick with this pre-SP1 relic...

people i know how to use google, if it was as simple as reading an article on ms support i wouldnt waste ~20hours allready on it... if after 2 days no one comes up with an idea to fool the system to reinstall SP1 ill just get over it and reinstall windows.... – n00b32 Mar 6 '11 at 17:02
Next time, think of a backup before an operation like that. – SvenW Mar 6 '11 at 17:08
The installer should not have a check if installed then tell user to go to hell... it should be able to install new files regardless of system state.. in my opinion... but ah well – n00b32 Mar 6 '11 at 17:34
