If you're like me, I am not looking forward to windows 8, so I will take advantage of closeout pricing and "stock up" on Win 7 licenses. Amazon is selling "Microsoft Windows 7 Home Premium Upgrade Family Pack (3-User)" for $115.

While it's an "upgrade", there is a Microsoft-approved process to do a new install with upgrade discs. First install the upgrade, but do not provide the software key when asked. This installs Win 7 in the demo mode. When finished, go to the DVD and click on "setup.exe" to start the install over. This time, enter the software key.
