Maybe if you remove/disable System File Checker (saves copies of Windows system files and Outlook Express etc in some subfolder of your Windows-directory) and System Restore. That's what I did, and I didn't remove a lot of other stuff, so my guess was that this was reducing my Windows so that my Windows-dir is only 585 MB after install. As for speed, I think Camarade Tux has made some good points. I'd like to add that you could disable all visual effects, that is, no teletubbie-interface but back to Win2K-style, and after installation go to System Properties (winkey+Break) > Advanced > Performance-settings and click Adjust for best performance. Also, go to Display Properties (Start > Run > "control desktop") > Appearance and click Effects. Uncheck the transition effects thing, the Shadows under menus and Show Windows contents while dragging. A lot of these visual effects are in nLite too, in the Tweaks-section under Visual Effects, but a lot of people, including me, have reported that the tweaks don't work. There's workarounds for that, but that gets way too complicated for now O, by the way, I think there's also a Performance tweaks-part in that same Tweaks-section. Do what you gotta do
