Fully updated Windows is always key, specially in XP days. I can't uderstand why a lot of people ignoring UpdatePacks and they crying and complaining. It's still same after another 10 years.
Yes, and of course there could be bugs. But I quess I must face these issues, when testing images on real machines.
Another point is, many "Windows XP Enthusiast" never have real XP machine and never used them, they are just too young..
