With the antitrust case against Microsoft, they had to change some things in XP Service Pack 1 and Windows 2000 Service Pack 3. There is a new Configure Programs in Windows 2000 with the new Tech Release Candidate. Although I"d have to say it doesn"t really do crap... On a good note, the installation went fast and smooth. Kudos Microsoft on that. I did a fresh install of Windows 2000, and just did the service pack after that. I was releived not to have 40 updates needed at the Windows Update Site. IE Updates, DirectX 8.1 and Media Player 7 showed as still available for download, and they all downloaded and installed without a hitch. As far as I know, this Service Pack Doesn"t expire. It also is about 123 megs.
