About This Software

Ever wanted to leave your amazing live wallpapers running without leaving your PC unlocked or waiting for your screensaver to kick on? This was made for you! We had the same problem, so we built a clean fix and added the common-sense extras we wanted too.

Press a global hotkey of your choice and your wallpaper fills every monitor instantly, with no waiting on the Windows screensaver timer. Use the Wallpaper Engine screensaver when it's installed, or pick your own looping video instead. Wallpaper Engine is not bundled with Wallpaper Lock and isn't required when you use the video option.

Snitch Mode: Catch Anyone Who Touches Your PC

Set an optional Input Detected Video that plays the moment someone touches your keyboard or mouse. Make it a "NICE TRY" warning, a jump scare, or a clip of you saying "I can see you." Leave the PC alone and it goes back to your wallpaper. If they keep going, Wallpaper Lock hands off to the normal Windows lock.

You control whether Windows asks for your password on resume, whether Wallpaper Lock starts with Windows, and whether to turn on an optional Quick Unlock Bypass with its own shortcut, press count, and timing window. It runs quietly from the system tray and supports single and multi-monitor setups.

Security Note

Wallpaper Lock is a convenience and presentation layer for your desktop, not a replacement for normal Windows security. Its video wallpaper and Input Detected Video surfaces are not as secure as the standard Windows lock screen, and the optional Quick Unlock Bypass intentionally makes returning to the desktop easier.

Use Wallpaper Lock at your own discretion in homes, studios, offices, or other low-risk spaces where showing off your setup matters more than maximum physical security. Don't rely on the video surface or Quick Unlock Bypass to protect confidential data, an unattended business computer, or anything where security is paramount. In those cases, use the normal Windows lock and require your password on resume.
