Recently I helped my aunt with her old computer, because it was constantly stuck on the activation screen. I searched through a bunch of forums to find something suitable, and finally tried
kms pico. Listen, everything went as smoothly as possible. The utility did its job in just a few clicks, and Windows started working like new. No viruses or strange processes appeared in the task manager, although I kept a close eye on it. My aunt has been happily playing solitaire and watching TV series for a year now, the system is stable, updates are installed automatically, and nothing has ever “crashed.” I recommend trying it, because the method has been proven in practice.
