I am putting together a second desktop computer for my partner for her to do uni work on.
Currently I am running windows 7 home premium 64bit on my PC, am i able to install the 32bit on the second computer and just buy an online activation OR is it required that I will have to purchase another copy of Windows 7.
Part of the issue will be making sure you buy a key that matches your media. The OS and the activation doesn't know or care if you used a brand new virgin disk or a disk that's been used on other machines. The issue is A) having a product key to activate with and B) it matching the type of media.
By "match" I mean OEM vs. retail vs. Upgrade, etc...
All that said, you can even re-use your x64 disk for your partners machine, again, as long as you buy the correct key.
