Activation of Windows

Activation is a mechanism which protects a system from piracy. When someone buys Windows 10 from their official website, then they get an Activation ID in their email.

That activation ID is exclusively for their system, and ensures that the user has bought a legal software. Legal software provides the user with product end support, and many other benefits, that getting an illegal key from online websites doesn’t.

Deactivating a key before selling a system should be done, so the buyer doesn’t end up using your Windows activation key. If he does use it, then you won’t be able to reinstall it on your system.

This would result in the seller buying a Windows 10 activation key again. It is very easy to extract a product key from the system, and deactivate it.
