Microsoft protects its software copyrights with Activation keys. When you purchased your copy of Windows 10, you were supplied with an Activation key that is necessary for you to use all Windows 10 features. Validation simply checks that Activation key against Microsoft’s database to ensure your copy of Windows 10 was not pirated.
However, maybe you do want to change that wallpaper or color. Alternatively, maybe you just feel bad and want to pay for a full-fledged license. Microsoft made this very simple. To buy a license to activate either Windows 10 Home or Pro, do the following:
1. Go to Settings
2. Go to Update & Security
3. Choose Activation
4. Select Go to Store
The Windows Store now opens to a product page for either version of Windows 10. You can now buy Home or Pro, and it unlocks and activates your version of Windows 10.
Windows 10 Home costs $119.99 , and Windows 10 Pro costs $199.99.
The purchase runs through the Store like any app purchase, and you can just use your Credit Card, PayPal, or whatever payment methods you set up.
Microsoft has actually opened up Windows 10. The fact that you can download the ISO and install it without a product key on any PC or Mac is neat.
The idea here, of course, is to get the OS into as many hands as possible. This tactic is not much different than Google and Android and giving it away for free (granted, there are patent fees).
Microsoft wants Windows 10 on every computer because it is the Store and their services that are important. This strategy means that Windows 10 can be put everywhere with a tiny drawback. Sure, you have a watermark, and you cannot change the wallpaper, but if you are a Mac user and you want to tinker with Windows 10, there is literally nothing stopping you. It just works.
Even better, Microsoft makes buying Windows 10 through an un-activated copy very easy with a mere Store purchase. You do not even have to leave the house.
It is a strange new world if you enjoy Windows, but a much more user-friendly one too.
