Microsoft is a bit of a stickler when it comes to Windows activation. As it stands, if you install Windows without a product key, you’ll be treated with a watermark on the corner of your screen and will also face some restrictions when customizing the operating system. That said, your PC will continue to work fine for the most part, so it’s arguably fair that the company places some barriers for customers who don’t activate their Windows using product keys. Now, it seems like the Redmond tech firm wants to go a step further in this area.
