how can i find windows 2000 product key from registry?
1 Solution
You can't
See HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion - the value to look for is "ProductId"

jkr is both correct and incorrect.  The product key stored there is a "translated" product key from the original 25 alphanumeric characters you entered.  You cannot get from the registry what your product key was to reinstall the operating system.

Yeah agree with leew. In Win98 the key was in the registry but in Win2000 only the Product ID is in the registry. If you lost your key then you have a problem because Win2000 does not log the key. If you registered the OS with MS then they may provide you the key. Then again they may not. If this is an OEM install then the key may be somewhere on a sticker on the mahcine.

The Crazy One
The way to install Windows 2000 without the product key.
Would be to first copy the folder "I386" on your CD
over to your harddrive. Next open up the file "SETUPP.INI"
and change the numeric value of

"Pid=51873000" to "Pid=51873270"

The value of "000" has been change to "270".
