WindowFullscreen Windows Last updated: October 1, 2026

WindowFullscreen Support

Give a regular app window more screen space. WindowFullscreen expands supported windows to fill a display, removes their standard frame, and restores their original position and size when you finish.

Features

  • Make supported windows fullscreen and restore them
  • Configurable toggle shortcut
  • Choose the target display
  • Keep the taskbar area
  • Restore all changed windows
  • Japanese and English interface

Use and limitations

Select a target and press Make fullscreen. Restore it with the same button or Ctrl + Alt + F11. Ctrl + Alt + F10 restores all targets. Display and taskbar choices apply to the next fullscreen operation. If a target is unavailable, choose a resizable regular app window with normal permissions. Exit waits for restoration to finish.
