Windows XP

Finally, a fricken OS that stays stable for more than 2 hours. However, the constant 'send error report' shit makes you want to vomit all over your monitor and shit in your hard-drive.

Fairly decent OS from Microsoft. More stable than most Windows versions, but has a number of privacy and end-user-rights issues that are questionable at best. Like all Windows builds, is often blindly flamed by idiots with no clue what an OS is or how it works, thinking MS sucks but not having any ideas how they would do it better.

Its Fisher-Price looking graphics do however fit in well, considering MS's tech support usually treats you like a toddler.

a computer that works fine. i have it and it never crashes. its awesome. just watch out for BSOD.
I once got a virus but it went away when i got AVG.
To some people, some people say ''windows xp is stupid'', well they should upgrade to Windows 7.

Windows 2000 with a tellytubby-style GUI.

A seriously stable operating system. The only reason it would crash, is if you dont know how to properly install new hardware, you built a computer yourself, but you mixed incompatible parts, or you have shitloads viruses and spyware, or because you were a jackass and messed with a program in a way it shouldnt be messed with.
Thankfully, you can turn off error reporting.

The first time microsoft didn't make an os JUST LIKE the one before it but gave it a different name.

The best damn operating system ever made, except maybe Windows 2000. So good, that people are still using it even after 9 years (an eternity in computer time) despite the fact Microsoft came out with two more Operating Systems since then.
