    Does Installing Windows 10 overwrite the Windows 8 UEFI password?


    I installed Windows 10 Enterprise from my work's license on a computer that originally came with Windows 8 Pro. I realized that I didn't want the Enterprise version since it requires me to check in with the KMS server, which means if/when I leave the job the Windows won't work.

    My question is, did installing Windows 10 and formatting the HDD overwrite the Windows 8 product key stored in the BIOS/UEFI? I found a few tools (including Belarc) that were supposed to pull product keys from the BIOS, but since I have Windows 10 installed it pulls a product key for Windows 10. I'm trying to find out if I can get an installation disk for Windows 8 Pro if it will actually let me install it or if it'll just prompt me for a product key (which I didn't write down before installing WIndows 10).

    The Product Key definitely is not written on the outside of the computer, and I tried contacting Lenovo support and they said they couldn't tell me the product code but they could sell me a recovery disk (which I'm pretty sure is just the standard Windows 8 Pro installation disk, which I'm not sure if it would work if the Windows 8 Product Key in BIOS was overwritten by the Windows 10 install).

    Thanks!

    :)

    Windows 10 Run DLL error message at startup

    The repair does require the same amount of space as the current windows 10 installed. The Windows 10 upgrade will overwrite the current operating system whether 7 or 8/8.1, the upgrade repair will upgrade you to the current Fall version of Windows 10.
    It would install on the C drive.

    Alas I don’t have any further options.

    Windows 10 32-bit native UEFI install on Desktop/laptop with processor intel core i3/i5 or its amd equivalent

    UEFI 2.0 support was added in Windows 8, so you're good to go w/ a native UEFI install of Windows 10 32-bit, if your system firmware supports it.

    Hi!
    No! The Key in Bios is stored for the lifetime of the Maschine. Win 10 don`t overwrite this key, Win 10 read only the key!
