Hello, I also recently assembled a system and encountered the same watermarks - they are really annoying. Since I am not a fan of complicated instructions either, I was advised to use
kms activator and it turned out to be a real lifesaver. It activates both Windows and Office at the same time in just a couple of clicks, which is ideal for those who don't want to spend hours on forums. The main thing is to find a reliable source for downloading. Everything works stably, all functions are unlocked, and the system has been running smoothly for several months without any problems or crashes.
