Is it possible to upgrade from WinME to Win2k ? If so how?
If not, then is this FAQ on http://www.ntcompatible.com/faq215.shtml wrong? Windows 2000 FAQ

Look here: http://www.microsoft.com/windows2000/professional/howtobuy/upgrading/path/default.asp

The problem is, WinME came out after Win2k, so Win2k won't be able to recognize the existing system files and interpret the system settings in order to make the upgrade. Anyone please correct me if I'm wrong, since I haven't tried it myself (I wouldn't touch ME with a 10-foot pole), but I think the FAQ is wrong on that one. I guess theoretically it would be possible to patch the Win2k installation program to tell it what to do, but I haven't heard of this being done...

I would call this a "downgrade"

Thanks a lot for the info. Technically its a downgrade but the fact remains that any upgradation is done to improve performance and stability. So I guess I can call it an upgrade :-)

Secondly, I thought their maight be an unofficial patch or something which lets you upgrade WinME to Win2k.

Hmm, you are replacing W2K with WinME in order to get more performance and STABILITY?

Nevermind....

Please read carefully. I plan toreplace WinME with Win2k

Do a clean install...otherwise you'll have a private hell for a while.

Yes it is possible to upgrade a WinME install to Win2000. I know because I have done it before. I did this just to see what would happen. When you pop the Win2k CD in on a WinME system it will ask you if you wanna upgrade, click yes and off it goes. No need to do anything else really. I think Win2k will treat as 98. However, once you boot Win2k you will notice a lot of QUIRKS! For one the taskbar properties will have all of Win2k's customization options as well as all of WinMe's. Yes there are lots of duplicate options. The "Effects" tab in Display is completely messed up with all of the icons named differently. [The recycle bins were named My Network Places]. Most of the shell icons are screwed as well due to lack of knowledge of Winme system files. Control Panel on start menu, is a paper document. Some other problems include less stability [the system crashed a lot], and some filenames were truncated to DOS names, and some programs pointed to wrong .dll files.

It works but it isn't recommended. If you are going to update, uninstall all updated drivers, use default WinME drivers, uninstall some Win9x dependent software, and hope.
