Hello, I have windows 10 currently installed on my laptop. It has been more than 30 days and I want to downgrade back to my pre-installed windows 8. I used the windows 8 setup from Microsoft and as I entered my key it told me that "This key doesn't work with this edition of Windows. Try a different key." the key I am entering is my MSDM key I have searched the Internet for days to no avail, please help in any way you can.
Thanks
Thanks
