    Problem. upgrade to Windows 10


    I have a used HP desktop, came without hdd. Win7 label characters on box was right rubbed off.
    I placed a hdd and got Win7 Pro installed and activated on the computer using Raymond tool (HAL9000)

    then I was trying to upgrade (NOT clean-install) to Win 10. started no any problems. (Win 10 Pro) installing until end, at end of upgrade, Windows pop-up a message, error of missing Windows key. therefore its upgrade failed. (restored Win 7 Pro).

    Can this computer be upgraded to Windows 10 Pro? or have to be staying on Win 7. no free upgrade?

    Thanks,

    What's the exact serial number(S/N) and product number(P/N) on that HP desktop?

    If Windows 7 Professional SP1 had legally been activated in that HP desktop, you should've been able to upgrade it to Windows 10 Pro and activate it.

    Because you activated Windows 7 by other means, it's my guess that's why Windows 10 failed to activate.

    It's HP Elite 8200 CMT

    It's with a COA label on box. but really no way to read it except "Pro OA".

    Thanks SIW2,

    It works for my HP Win 7 Pro.

    I did fresh-install Win 7 Pro again and took your tool to activate Windows. It's noticed that Win 7 activation is with HP OEM SLP key (While HAL9000 key is computer-specified).

    Weekend I am going to re-install/upgrade Win 10 and will post back the result. hopefully it can be upgraded to Win 11. I did test Win 11 saves memory a little. and runs fast a little, for this old HP computer.

    It is not mine, it is hp. Saves having to download the gigantic recovery iso file.

    Right,

    I had stored HP Elite 8000 recovery file almost ten years (key F11 for HP System Recovery).
    This tiny tool (only 3 KB) right does same job.

    Update

    Win 10/11 install/upgrade went through smoothly in my test. Computer activation: Win 11/10 Pro. Windows is activated with a digital license

    Desktop PC, HP Elite 8300 CMT. It was running Windows 7 Pro, GPT partition.

    This weekend I did fresh-install, when done, it's noticed that PC NOT activated. The HP OEM Win7 activation tool was working on HP Elite 8200 CMT last time. no idea why this time it's NOT working.

    Update

    After the hdd changed to MBR partition, the HP tool is working.
    i.e. the HP tool works for MBR partition.

    When using the installation media You have to use a windows 7 retail key when downgrading to windows 10.

    You can also create a bootable USB with the installation media and you won’t be required to enter a product key
