What is activate-watermark?

Activate Watermark is a small Windows desktop application that adds a fake "Activate Windows" watermark to your screen, the same floating text that appears in the bottom-right corner of genuine unactivated Windows installations. The program does nothing to your actual Windows activation status, it is purely a visual prank. The watermark sits permanently on top of everything else on your screen, lets mouse clicks pass through it so it does not interfere with normal use, and leaves no icon in the taskbar. A right-click menu in the system tray (the small icon area in the bottom-right corner of the Windows taskbar) lets you adjust several settings: move the watermark to any corner of the screen, change its opacity from mostly transparent to fully visible, resize the text from small to extra large, and edit both lines of text to display anything you want instead of the default "Activate Windows" message. Exiting through the tray menu or Task Manager removes it. The README describes use cases as pranking friends, looking unserious during screen shares, or general amusement. The program is built as a single executable using C++ and the Win32 API (the programming interface for building native Windows applications). Building it requires Microsoft Visual Studio. It is released to the public domain.
