I have been fighting this update problem for some time. I did not load 8 on the PC, someone else did. I would like to go back to 7, which was on it prior to the upgrade, or in my mind, the downgrade to 8. It had Windows 7 Home Premium, which I would like to go back to. I do not have any CDs from when 7 was installed originally. It does have a sticker on the PC with the key for 7. My question is this: If i can get my hands on a 7 cd from a friend who has 7 on their PC and use the key from the sticker on my PC, can I just load 7 as normal? Never did this before, so any input would be greatly appreciated.
