Question of OEM Windows 10 Pro down grade to Windows 8.1 RRS feed

  • 問題

  • According to the rules of Microsoft, can I directly down grade the OEM Win 10 Pro to OEM Win 8.1 Pro since some of the drivers of the bar code system cannot be supported by win 10? 

    If I can, do I need to re-install the Win 8.1 with the OEM Win 10 CD-key?

    Hope someone can help! Thx a lot!
