What is your favorite OS?

Windows XP Professional is the best version of windows I feel. It is the most comfortable environment you could work with , It is safe and easier to use. Now the newer version of windows .... Windows VISTA is out. It has a 4 level security to its kernel and offers high performance and stunning features like AERO etc...etc...though it has some problems now IT will be rectified in the near future. So I think I will be taken over by VISTA... AND for your information In 2011 The ultimate version of windows....WINDOWS 7.0 is going to released....

Windows200XP. it is fairly stable and it has been working pretty fine so far. Earlier, I used Windows98 and that was also good but inferior to Windows200XP. Windows200XP gets updates through online and it is nice to be updated like this periodically
