Hello guys, i am Pieter and i am going to build my first gaming pc. But when it comes to installing Windows i am a little bit confused and i don't know what to do. In a video of Paul's Hardware i saw that he used the Windows Media Tool to compress his Windows into an ISO-file and put it on a 4 GB USB-stick. He later plugged it into his pc and used the ISO-file and installed it as Windows but he had like a watermark in the right-bottom corner which said something like: windows not activated. But my question is: Do you really need a activation key to use Windows properly or should i immediately buy one and use it right away. Also is G2A a safe place to buy an activation key for Windows because Ed from Techsource is constantly talking about it.
