While there are a few technical exceptions, which we’ll explain below, the plain truth is that Windows can only be installed on one machine. The licence agreement issued by Microsoft is quite clear about this, and when you enter the product key during the installation process Windows locks that copy of the software to that particular PC.
It might seem perfectly reasonable to expect that an item you purchased can be used in ways that you deem fit, but Microsoft doesn’t necessarily see it that way.
But there are options open to those who want to move Windows 10 or even old favourite, Windows 7, to another PC.
