Windows 7: Reactivating Windows 7 with fresh install

Reactivating Windows 7 with fresh install

I installed Windows 7 Home Premium over Vista Business on a PC to see if it would run and tested it out for a few days. I used my installation CD that was good for only one PC. So to activate Win 7 on that 2nd PC I need to buy another copy of the OS. Can I just reinstall over the current version of Win7, or so I need to wipe the drive and install fresh?

Since you can only use one installation at a time, you need to choose which pc you want Windows 7 on. The other is going to have to run another os unless you buy another copy of Windows 7.

Not exactly... I installed Windows 7 on two PCs using a CD that was licensed for only one PC. So now I need to buy another license and install it on the second PC. So can I just insert the CD and reinstall on the 2nd PC, or do I need to erase the HDD and reinstall fresh?

Awesome! I see the System Properties > Windows activation information on my current PC. On the unactivated one I assume I'll be able to change that (Not in front of that PC at the moment).

So to follow up, two PCs have the same copy of Windows 7 Home installed. I need to install another OS on one of them. So can I:
1. Upgrade PC#1 from Windows 7 Home to Professional via an upgrade
2. Then use my original Windows 7 key with PC#2?

No, because Windows anytime upgrade requires your pc be activated before you upgrade. Even after you upgrade, your pc will still be activated with the Windows 7 Home Premium product key along with the new Windows 7 Professional key. I know about this because I use Windows anytine upgrade on one of my computers.
