Windows 10: OEM License after HD ZeroFill? Solved

    OEM License after HD ZeroFill?


    Hello Everyone,

    I am selling my Dell laptop to a friend and I wanted to be sure that none of my files will be accessible to him, for this, I chose to do a zerofill to my hard disk.

    The reason I'm posting here is that I am afraid that this will wipe the license information in my computer and he will not have a win10 license anymore. My computer has 9 partitions, two of which are named "Recovery and OEM". If I zerofill everything but these two, will it work?

    What other method should I use? My laptop came with OEM 8.1

    Thank You

    Don't worry about it. The same version of Windows 10 (home or pro) will activate itself after a clean install. It will either use the Windows 8 product key in BIOS or UEFI placed there by the manufacturer, or retrieve the digital license from Microsoft Activation servers stored there based on the unique hardware ID of the computer which was uploaded and stored when it was upgraded to Windows 10.

    Welcome to TenForums @hugorafael

    For a Windows 8 PC the product key should be embedded in the bios. You can check that with ShowKeyPlus.

    If you purchased a new PC running Windows, the product key will be included in the firmware in the case of Windows 8 or 10

    Thank you for your response!

    So I ran ShowKeyPlus and saved a key backup file, now I should be OK wiping this hard drive new as long as I use this same key?

    It showed as "OEM Edition: Win 8 RTM CoreSingleLanguage OEMM"

    Thank you!

    But one of the 9 partitions in my HD is called "EFI System Partition" this will be wiped too, is that any problem?

    I saved my key using @Brees tip

    No problem. Windows will recreate it when reinstalled.

    Be sure you download the windows 10 Home single language version.

    Currently the install iso or USB made by the Media Creation Tool includes four editions: Pro, Home, Home (Single language) and Education. Setup will either install the edition appropriate to the key, if it can find it in your bios, or give you the choice if it can't. You can use DISM to check what's in your install media.
