Windows 7: What was the worse OS that you have used? (not just windows)

Hello guys,

What was the worse OS that you have used? (not just windows)

For me, it was Windows ME, to me it was just Windows 98 with some big updates. But I say that system restore was a good idea.

Windows 8, and iOS 5 until they made it half decent 2-3 months later. Man, iOS 5 was what you'd call a bad Apple...
I wore out my battery on my iPod Touch 4g because of the excessive recharging (my theory) and it was dog slow until they released 5.1. It works better now, as long as I don't restore from backup when I restore my iPod.

Windows Mobile <6.1
Ubuntu with Unity
Vista

I haven't found any that are bad, all the ones I've used have worked as they should and not given me any problems.

Windows ME for me too but I only used it for maybe a week.

One morning I booted it up and then went into the kitchen to make coffee.

When I came back to the computer, all my desktop icons were Recycle Bins.

I still have the CD somewhere.

Windows Vista,crashes after crashes even after being fully updated with drivers and all and reinstalled 4 times in a row along with black screens.Random slow downs even with 3gbs of ram and a nvdia card with more then enough ram with the correct drivers.Replaced it with windows 7 and no more problems,they vanished.Had to suggest it to my uncle to upgrade and he said fine as long as it fixes it and he's very happy with windows 7.

I'd have to agree with Windows ME... It refused to install for me seemingly no matter what I tried.

I would say that No OS I've used is bad

I'm 13 and I've used
Vista
Xp
7
8
ME
2000
95/98

Definitely Windows Millenium for me. It is the only OS, and I've used many, that would completely lock my computer so the only way to shut it down was to pull the power cord.

Windows ME. Period. It gave ME problems
