I loved windows 98. I never bought or upgraded to the 2000. I just heard to many complaints about it. But I have the XP. I am pretty satisfied with it and find it really easy to learn and navigate.

My old time favourite would have to WIN 95. It is not as good as XP, but it had less problems.

It's probably be Windows XP SP 2.It was the best OS i've ever used.
Windows XP is way ahead from other Microsoft OS in terms of speed and usage and also reliability.

xp all the way
xp pro to be more specific

Add me to the small list of those choosing Windows 2000. I love it. I'd used it now, but my spouse prefers XP and we share a PC... so, I'm letting her get her away.

I think someone said Win 2K is user-friendly in an earlier post, and I completely agree with that statement. I've used it at several jobs over the years and prior to Windows XP's release. XP was kind if hideous to me in the beginning.

I was forced to switch to XP Pro since some of my software wouldn't run under WIn98 any more.

I liked Win 98 as it had less of security problems as strange it might sound.

Windows XP is pretty and stable, but I hate keeping track of all the updates.

i think i only experienced using windows 98 and xp...i like xp...windows 98 was fine too...

MS WindowsXP Pro, All the way............................ Devildog

Id have to say XP as its the one i have used most..BUT there are so many bugs with all operating systems it annoys me to be honest.
I wish that they would bring one out without the bugs, but hey then they wouldnt make as much cash...and well they cant let that happen can they ....

by now XP is the best in windows , whereas fedora linux is also good
