Will Windows 8 OEM be accepted by Windows 10?


I have an Dell Inspiron that came with Windows 8 preinstalled and I have my Windows 8 OEM key stored in the BIOS not on the hard drive. I upgraded to Windows 10 from 8.1 recently but I want to do a clean install (use a windows 10 original ISO and completely wipe my hard drive). When I tried this a year ago with Windows 8.1, it didn't recognize my Windows 8 OEM key and I had to install Windows 8 then upgrade to 8.1, then again upgrade to Windows 10 recently.


Will the Windows 10 installation program recognize my Windows 8 OEM key? Or will I be forced to install, upgrade, upgrade again and clean?


Answer



Let us start from when your PC has factory installed OEM Windows 8.


For Windows 8.1 :



  • If you have upgraded from Windows 8 to Windows 8.1, its fine.

  • If you want a clean install, use "Windows 8.1 Update 1" OEM installation media of SIMILAR EDITION as of your original Windows 8, it should accept your Windows 8 key retrieved from BIOS.



    • If not, install using generic key for Windows 8.1 from Microsoft
      website, then activate later from Windows Settings (Online or By Phone).


  • Any other options will not work.



For Windows 10 :



  • If you upgrade from Windows 8.1 to Windows 10, all good.


  • If you want a clean install, you MUST upgrade to Windows 10 at least one, then clean install using SIMILAR EDITION OEM installation media, it should not ask for any key.



    • Even if it does ask for key, use generic key and activate later from Windows Settings (Online or By Phone).


  • If you never have upgraded to Windows 10, there is no way to clean install Windows 10 using Windows 8 key, at least as of now.
