I have bought an acer laptop with windows 8.1 pre-installed in it. Now I want to downgrade it to windows 7 because I am not liking it. When I tried to download windows 7 ISO file from microsoft situate, i
am asked for product key. When I entered my product key of windows 8.1, the corroboration process fails and displays and error message “The key you provided is for a product not currently supported by this situate or may
be invalid. Please try again or call on the Microsoft Fund Contact Us page for assistance.”
Can I downgrade my windows from 8.1 to 7 with original windows OS.
The 8.1 PK will not control on 7.
And the Microsoft website 7 ISO download is only for Retail Windows 7 PKs.
You only have downgrade rights if you have Windows 8.1 Pro > to Windows 7 Pro, etc. (read below).
If you do not have Windows 8.1 Pro, you have to buy Windows 7.
