There are two methods that I know of for finding the key
Start >> Run
Type in Regedit
GoTo Edit >> Find
Type in ProductKey (no space between words)
Hit Enter
Be patient. Edit takes a few moments to work.
You\'ll be taken to the key where you can see the 25-digit key
the other si to open regedit and go to HKEY_LOCAL_MACHINE key
Software
Microsoft
Windows
CurrentVersion
Now, locate the ProductId value in the CurrentVersion subkey.
Here, you\'ll find a copy of the entire certificate number in four
groups of five, three, seven, and five numbers. The CD key number
you need to install Windows 95 is made up of the second and third
group. Simply write down this number and close the Registry Editor.
