Updating windows key
Granted, not all problems are the same but mine is as close as it can get.I bought a Win7 Ultimate from a download website that was claiming to be legal. Be that as it may, soon after a popup appears telling me that the product key used is illegal, so I've bought a new one, this time from a reliable retailer shop.
Sadly, that period has long since passed, as the free upgrade progamme came to an end on 29 July 2016.
Before you get the nag: You must activate windows, windows will be fully functional.
The second problem is that Microsoft only allows you to download Windows 8.1 installation media with a Windows 8.1 product key.
You can’t normally download it with a Windows 8 product key.
We’ll assume you’re creating USB installation media for this process, as it’s the easiest way to do this.
