I'm probably just overlooking something here, but heres whats happening: I have an XP disc, genuine, build 2600 of xp pro sp2, oem. Came with my laptop, and since its oem, I was able to use it with my custom built desktop:) It already has IE7 and WMP11 on it, but when I slipstream SP3, IE7 is gone, as well as WMP11 and I'm left with WMP9 and IE6.... I thought "okay, I'll just slipsteam IE7 and WMP11 back into it". No avail. It just gives me some kind of prefetch error after the copying of the files and rebooting into graphical setup. Whats going on here?
