Windows 10: Can't activate Windows - Error code 0xC004F074

My PC was custom built by a computer repair store, and my Windows activation keeps telling me that it isn't activated. I will attach a screenshot below.

ERROR CODE : 0xC004F074

Hello,

I bought my HP laptop with windows 10 Pre-installed on March 2016. Recently a message started poping up saying

"YOUR WINDOWS LICENCE WILL EXPIRE SOON"

You need to activate windows in your settings.

And in the settings a message shows " Your windows expires on 08th August. Contact your system administrator to get a product key. ERROR CODE : 0xC004F074 "

I tried to activate it with product key I got when I purchased the product as suggested by 'https://support.microsoft.com/en-us/help/10738/windows-activation-errors' . But it shows that Windows
can't be activated with this product key. Go to settings for more information. Error Code : 0xC004F074

Please help as to what I need to do to activate my product.

Thanks,
