So, I've got the one PC, running W7 Home Premium 64 bit. I don't have a disk for the OS, just a sticker with the serial number on it.
Now I've also got my laptop, running XP 32 bit.
I'd like to install W7 over XP on the laptop. As I don't have a disk for W7, am I supposed to download it and use the serial I already have (assuming I'm allowed to have the one OS on two machines?)
If so, do I download 32bit or 64bit? The license is for a 64bit OS, but will the laptop take a 64bit OS?
