I am having Latest Acer Switch Alpha 12 and it came with Windows 10.

 

I want to install Win 7 on it, but before proceeding further i want to ask:

 

If i delete all partitons on my SSD and install clean copy of WIn 7 SP1 on my laptop now and after a few months when i would like to again install Win 10... Would i be able to activate it ?

 

I fear key will be overwritten in hardware by Win 7 and i will loose my copy of Win 10.

 

Please advise.

    Hi,

     

    I am not sure if the key will be overwritten in the BIOS. I don't think so.

     

    But you can try to retrive the key from BIOS and save it somewhere and when you will reinstall windows 10 you can use this key.

     

    There is a tool here: http://www.intowindows.com/recover-windows-product-key-bios-efi/ but I never tried it so I don't know if it works.

    key will not overwritten.

     

    the main issue will be windows 7 installation, since you will miss some drivers, most important will be thermal control and power control.

     

    i also quite sure that Legacy setting is missing too on BIOS.

    IronFly - Yup, i am simply not able to install Win 7 no matter what i do. There is an option in Bios to put it into Legacy mode.

     

    I have burned Win 7 usb with usb3.0 driver injected but it gets stuck at windows logo during installation. I tried using external DVD drive, but have error that corresponds to missing usb 3 drivers.

     

    Can u link me to any utility where i can usb 3.0 drivers tht is compatible with acer ?

    I don't have a link for that, by the way, i insist that you stay on win10, since (as i already posted), the main issue will be thermal and power control drivers.

    It's the same issue on Switch10 and not having these 2 drivers can cause overheat and high battery consumption.

    Yeah, the Switch Alpha 12 runs hot enough when the proper drivers are running. Downgrading to 7 would break that and I'm sure shut it down within a few minutes at best. The nifty cooling works quite well under Windows 10 though.
