The W98 ProductKey is generally found on the Windows user manual, the
certificate of authenticity, a sticker on the PC or a sticker on the sleeve
or jewel case the Windows CD came in. The 25-digit key is 5 groups of 5
alpha/numeric characters. The Key might be available from the system:

If the system is working in either safe or normal mode:

Open regedit.exe to this key and look in the right pane for the entry
ProductKey:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion

If the system is not working, start the computer with a floppy startup disk.

At the A: prompt, type: C:\Windows\Command\Find /N "ProductKey"
C:\Windows\System.dat
(Note: ProductKey must be typed in upper and lower case letters as shown
and there is a space after: "Find" after: "/N" and after:
"ProductKey"

If the hard drive has been formatted, US customers can contact Microsoft at:
1 800 642-7676. They will issue retail and OEM product keys after verifying
data located on the W98 CD.

Having used a recovery disk on an old H.P Pavilion with
Windows 98, I discovered that I could not find the
original Certificate of authenticity which had the
product key. As a result, I am unable to operate the
computer. Is anyone able to help or advise me. Thank
you.
