Well... aside of being free of most crap I never used on XP Pro... I only have 256 RAM and my machine never passes half the RAM used.

Windows XP Lite only occupies 1GB of my HDD.

Although I haven't really pushed the machine to its limits, like Lucifus for example, it has worked very nicely ever since I got this hack from a friend. I formatted and he gave me the disc to install this version.
