Finding the Windows 98 Product Key.

Because you were asked for the Key when you first installed Windows, it's saved in the Registry. Even if you are unable to start Windows, as long as you can get to the command line,(a C:\ prompt) you can run this on the SYSTEM.DAT file that's part of the Registry. For Windows 98 installations, type: find.exe /I "ProductKey" %winbootdir%\SYSTEM.DAT The first line of the values returned should show the product key in a form similar to: ?????-?????-?????-?????-?????.
