Windows Anytime Upgrade . As you're probably aware, Windows Vista comes in a number of different editions: Home Premium, Business, Enterprise, and so on. (Details are in the Introduction.)
But what if you buy, say, the Home Basic version, but you later decide that you really wanted the cool looks and video-editing features of Home Premium? Or maybe you bought Business, but you really crave the backup and encryption features of Ultimate?
Not to worry; Microsoft has made sure that you'll be taken care of. Using this command, you can upgrade your version of Vista to a higher version; all you need is a valid credit-card number and a few bucks in your account.
When you choose this command, you go online to the Windows Anytime Upgrade Web page. This site detects which Vista version you have now, and offers to show you what kind of happiness awaits when you upgrade to one of the higher-priced versions.
If you decide to move ahead with the upgrade, you're asked to find your original Windows Vista installation DVD. (Little did you know that it actually includes all versions of Vistabut holds back certain features that you haven't paid for.)
The upgrade process doesn't disturb any of your programs, settings, or documents. Everything remains exactly where it was (although Microsoft does recommend that you make a backup before upgrading, just in case).
