The only fix that works for good: activate the system, watch the watermark disappear.
That "Activate Windows" text sits in the corner of every screenshot, every recording, every fullscreen video. Wall-of-text tutorials tell you to edit the registry or run sketchy scripts. Spoiler: they come back, because the watermark is just the symptom — Windows is not activated.
When Windows activates through the local KMS server this tool installs, the system reads as genuinely licensed. The watermark disappears on the spot — along with the locked personalization settings. A background renewal keeps the license alive, so it never comes back.
