idk, my comp is pretty fucked up... i have alot of shit in my computer and dont feel like uninstall cuz its too much shit, also many errors.. fuck it... if i reformat mah pc, the only thing i'd back up is mah music and fruity loops
The best computer is a reformatted one.
Just back the needed shit up and fuck the rest.
Btw, don't install Windows 7 if it's your main computer, once it's out of BETA you're fucked.
You'll need to get a key and the updates from another pc most likely.
