Windows 8
If you are planning to upgrade your Windows 7 or Vista machines to Windows 8 but haven’t initiated the upgrade process yet, consider doing it today.

The Windows 8 Pro license (includes Windows 8 Media Center*) is currently available for $39.99  but starting February 1, this discounted price will no longer be valid and you’ll have to shell out $199.99 for the Windows 8 Pro upgrade license and an additional $9.99 for the Windows Media Center pack. That’s a saving of about $170.

Here’s a detailed guide on how to install Windows 8. You basically run the Upgrade Assistant to determine if your machine’s hardware configuration and the installed software applications are compatible with Windows 8. The wizard then pretty much guides you through the entire process.

Also, if you upgrade from Windows 7 to Windows 8, you will not be required to re-install any of  your existing applications and the files and program settings will be preserved as well.

[*] You will need the Media Center pack to play DVD movies since Windows 8 no longer ships with a DVD player.
