XP is based on Windoze 2000 which is based on Windoze NT. Windoze ME is a fixed version of Windoze 98SE which fixed some problems in Windoze 98, which repaired Windoze 95, which is based on Windoze 3.1, which is built on MSDOS, which was stolen from CP/M-80.
There's a big difference between XP and W2K versus Windoze NT. Microsoft tried to rewrite the drivers for NT using a different system than the previous Windoze 95/98/ME. However, there were 10 times as many drivers available for 95/98/ME than for NT. So, with Windoze2000 and later XP, they want back to the 95/98/ME standard. In general, XP and W2K drivers are very similar to 95/98/ME but unfortunately, not interchangeable.
Probably the defaults. Is there a reset to defaults button?
