Windows 7 came out today. The upgrade copy of it is considerably cheaper than the regular copy. With Vista, you can only do a upgrade and still be able to use and active with the key given with the package. Although there was a workaround (install a lower copy of Vista using your upgrade DVD, then upgrade it to the version you’ve purchased), it just wasn’t a very practical solution. With Windows 7, you can use your upgrade DVD and upgrade key to install a nice clean copy, AND activate it!

Just go into the installer like normal, and choose Custom (Advanced), format the drive, and install it. When it’s done, activate, and enjoy using Windows 7.
