A much user-friendlier and hardware supportive version of the Microsoft Windows NT family of Operating Systems. Windows 2000 while not officially declared as NT 5.0 is basically just Windows NT 5.0 with Plug and Play support, EFS, NTFS 5.0 and a host of other features that are not available in Windows NT 4.x.
Windows 2000 is the best microsoft operating system available right now.

Probably the only fast and stable OS Microsoft has ever made. Windows 2000 (aka: Win2k) is based on the NT 5.0 kernel and is the predecessor to Windows XP, it's obese cousin.

Win2k will run almost all software made for WinXP, but since M$ wants your money, they have begun to intentionally cripple software to only work under WinXP, eg; Windows Media Player 10.
Being both fast and stable, this was contrary to Microsoft's commitment to bloated and buggy software, so Windows XP was released to address the issues with Windows 2000.

Looks like Windows ME, sounds like Windows ME, tastes like Windows ME. But, brother, it ain't Windows ME. I would give half a lung (not MY lung, mind you) to get this OS, or atleast WinXP.
Mmm... Win2000.

A windows operating system that is alot more stable then the Windows 95/98/ME series. More up to date then Windows NT. ALOT MORE FASTER AND SMARTER THEN WINDOWS XP. Only M$ operating system worth dual-booting with your Linux/BSD/Solaris/BeOS machine.

A mistake made by a programmer, who accidentally added two extra zeroes at the end of what was supposed to be Windows 2.0.
Oh crap!!! We shipped Windows 2000 with the wrong name!

Meh, no-one will notice.
