One of my older PCs needed Windows reinstalled, and once it booted up, the activation reminder was stuck in the corner like a permanent overlay. I wasn’t about to pay full price for a key just to get rid of a watermark on a backup machine. I went ahead with kms activator to sort it out, and the process couldn’t have been simpler. Ran it once, no system slowdowns, no errors, and the activation stayed in place even after running a few system updates. It got the job done quietly without messing up anything else on the machine.
