Im just curios to see what you people use

use XP Pro on 2 different partitions (one for backup incase main os takes a dump on me) and use knoppix on cd as a backup of a backup! 

Linux is free and good, without many bugs like in windows

dont forget without any drivers as well! (uh oh, now everyone will jump me) 

XP up 2 date 

7-1 lol, I use also 98 and I will upgrade this one for 2000 maybe. (I have 2 partitions, one with xp sp2 and other with 98)

2k is good, its something betwen 98 and xp Now i installed winxp on secondary prtizion cause i need to use some programs in here O.O

i will be upgrading to Vista Ultimate soon when i get my new Pc

i use a custom xp lol

i will wait until they come up with Service Pack for Vista b4 making the jump, i hear too many horror stories about it, i want to sleep at nights 

bullshit, there is no "horror stories" with vista, its just a bid to make people not to use vista, cause people think Microsoft are shit at coding software, they are not.

i installed it in December, and i have not encountered any bugs or crashes ever since

same as when XP came out
everyone was like i won't use XP i will stay win 98 lol..
and i dont see much people on win98 now..

still on windows 95 

i use xp cause vista has many bugs

XP updated
