Where can you find the OS serial number or ID tag?

For the Windows serial number, go to Start, Settings, Control Panel and double click on the System icon. The information you want should be located on the General tab under "Registered to:". The PC should have its serial number somewhere on the backand some of the newer ones have them on the sides. The software for Windows should have the serial number either on the CD or on the book that came with it. If it was installed on the system when you bought it, you would need to look in the control panel if you don't have the documentation. Good luck.

in the registry, run regedit.
for nt it's in : hkeylocalmachine\software\microsoft\winnt\current version.

it's in a similar patch for the other os's.

If Windows won't start, using a boot disk, boot to a dos prompt. Change to the Windows directory and run "edit.com". Open "system.dat" (one of the Registry Files) and search for "ProductID" ....this will take you to the original CD Key....in the same area of the file you will also find Registered user, Organisation and the Digital Product Key.

This information is useful if you need to re-install W9x from a different CD but maintain the original owners licence.
