Windows 7 Upgrade Made Easy

Windows 7, Microsoft Corp.'s new operating system due out next week, is giving the company a lot to be happy about. By early reports, it's fast, easy on the eyes and fixes most of the problems that plagued its predecessor, Vista. But while Microsoft employees are doing the dance of joy, some consumers are confused and scared about the prospect of upgrading their computers to Windows 7.

The upgrade from Windows XP to Windows 7 is particularly daunting because it requires first wiping the computer's hard disk to perform what's called a "custom" or "clean" install. This clears out the old operating system—as well as all of your programs, files and settings. To save personal files, XP users must back them up first, typically on an external hard disk, then transfer them back. Programs, however, will be lost altogether, so users must re-install these using their original CDs or installation files, and then also re-install all the program updates they've accumulated over the years.

People upgrading to Windows 7 from Vista may have it easier. In some common cases, they can upgrade to Windows 7 "in place," which means they can save programs, files and settings right where they were. But since Vista was such a dud, many Windows users still use XP.
