Yep Paul Thurrot of Supersite for Windows is at it again. This time he has compiled a very handy article called: Windows XP Installation and Upgrade Overview. He has broken it down into 2 pieces, the second entitled: Using the Windows XP Upgrade Advisor.
Here is a blurb: "How you view the move to Windows XP will depend largely on your background. If you're a Windows 98, 98 SE, or Windows Millennium Edition (Me) user, Windows XP is a massive upgrade that shouldn't be undertaken lightly. To users of Windows 2000 Professional and, to a slightly lesser extent, Windows NT 4.0 Workstation, however, migrating to Windows XP should be painless, with a few exceptions. But regardless of which Windows version you're using now, how you make the move to XP is an important choice."
