    Hi Everyone!!!!

    I have approx. 160 Lenovo PC with Windows 10 Professional Preloaded, now this needed to be downgrade it to Windows 8.1 Pro. i need to know a way to downgrade this without doing a phone line activation as it takes time.

    if i do a fresh Windows 8.1 Pro Installation will the Windows Activate using the BIOS Key? do i have any way of doing an offline activation for it. please advice.

    thanks in advance,

    Shakir

    If your computer came with Windows 10 installed in, what the hell, should have be installed Windows 8 key in BIOS?

    do you mean to say that Windows 8.1 should get activated without an issue?

    As far as i know, somewhere in settings you have an option to roll back to windows 8.1 for 1 month from the time windows 10 was pre-installed. If that is present, roll back, and then find OEM key through RW and then note it down. Do clean install & activate with OEM key.
