Usage Guide
Features
Simulates Windows and macOS update screens with adjustable speed, one-click fullscreen, and Esc-to-exit. Great for slacking off, pranking friends, or meeting demos. Runs entirely in the browser — no install needed.
Steps
Choose a system (Windows or macOS) from the "System" dropdown; pick very slow, normal, or fast from "Update Speed"; click "Start Update" to launch the simulation — the progress bar advances to 100% then resets automatically; click the "Fullscreen" button in the preview card header to enter fullscreen mode where the update screen fills the entire screen. Press ESC or click "Exit Fullscreen" again to leave; pressing Esc anytime during the simulation exits immediately.
Notes
This tool only simulates the update animation and does not touch your real system. macOS mode shows an Apple logo and estimated remaining time. The simulation stays at 100% for 3 seconds before returning to the initial state.
