On my laptop I currently have a vlited Vista and a nlited Win2k on separate partitions. My Win2k installation is used purely for online multiplayer games where they perform dramatically better, which is likely due to the os using approx. 500mb less ram than my Vista. My nlited Win2k cd was 70mb, and I had basically removed everything from it that I did not need to run these games. My laptop has 1.5gb of ram, and a 1gb corsair turboflash usb drive which is used for Readyboost in Vista and for the page file in Win2k. My question is - if I had created a similar WinXP install with the same purpose as my Win2k installation, would WinXP show performance gains over my current os? I have noticed that people are able to create extremely small WinXP's.
