activating windows 10

I have just had a Mother board CPU and RAM replacement done.

I have gone through all the steps to reactivate Windows as per the help.

This was a digital upgrade from 7 Pro-10Pro

Change Product Key to the default etc.

still will not activate.

any suggestions?

 

Windows 10 expiring activation problem


I have a pop up message appearing on the screen saying the licence will expire 15 August, need to activate Windows in Settings. Contact admin to get product key.
When I go to Settings it says Windows is activated and Product ID as well as Product Key is listed.
I have tried all suggestions from the Microsoft forum to no avail.
I am now wondering if the technician who installed Windows 10Pro, installed the wrong programme.
I believe that the previous Windows in the laptop was Windows 8.1 home.
Could this be the problem.
Any help appreciated. Thanks.
