Hi guys I've did a bit of searching but cant find the info i'm looking for.
Basically I currently have the 32Bit of Windows 7 Professional on my PC (I was really sure I had 64!) so when I've come to install 4Gb of ram it only shows 3.2...
Can I just pop in a Windows 7 Pro 64bit disc to upgrade with my current CD Key? Or do I have to buy it again?
Though I think I'd rather do a wipe and clean install, so would that be okay? I wont get bothered with any "this key has already been used" messages will I?
Thanks in advance
