Question about Microsoft Windows 98 for PC

1 Answer

I lost the serial number for windows 98. When I recovered the drive it won't proceed to run Windows 98 without the serial number. How do I recover this or bypass it?

    It will not run windows because it stops at the screen asking for the serial number.

    Your link to nirsoft doesn't seem to mention Windows 98, and I am not quite clear on how I could use the utility if it covered Windows 98. Please advise.

    I have a Windows startup disk that runs off the old floppy. IT DOESN'T SEEM TO restart Windows but gives me a DOS screen. It loads "diagnostic tools" that don't seem to go anywhere and then stops.

    Thanks for the info, In the end I used your key to get started. It was accepted.
    Previously I had bought a Windows 98 SE upgrade CD which I was unable to use because of all the Windows Update files that stuffed the drive. That was why I had done the drive recovery in the first place.
    Today, after using your key to start Windows I was able to install the SE upgrade and now have the new product key on the system. So, thanks for your help.

    As a follow-up:
    I re-installed much of the software that I had on the computer before, and recovered files from the D partition on this IBM ThinkPad that I had bought new in 1999. I used the internet once during that time and may have picked up something. Here are some quirks that may be unrelated, that I cannot seem to solve.
    1. Everytime Windows98SE starts the screen says that windows is starting for the first time. That "first time" bit never goes away.
    2. Part of my ThinkPad Configuration Utlility seems to have been destroyed as it cannot give me any information on battery operation or power management.
    a) Do you know where to find that utility file for the 390E now that IBM no longer supports any of these computers?
    b) Do you know where one can buy the last lithium ion battery that IBM offered for the 390E?

    3. Also, after start-up, or at the end of it, a DOS window pops up that refers to acs.exe: "C:\windows\System> C:\windows\system\acs.exe -h". I have never seen this before, don't know what it does and have to close the window manually.

    Any ideas for these problems?
