Damn, I don't want to update my XP to SP2 because of the incompatibility to older games!

I heard that most of the older games do not work with XP with SP2!
Is there no other solution??? I would really appreciate having the chance to play this game without DVD finally, but like I already said I don't want "XP - SP2" on my computer!
Another Question: Is the crack really a NO-DVD FIXED EXE or is it only a BACKUP-DVD FIXED EXE??? When it is only a BACKUP-DVD-CRACK it's senseless for me, because then I can also put in my ORIGINAL-DVD in the same time!
