What is Fullscreenizer?

Fullscreenizer is a Windows utility for moving a windowed game into borderless fullscreen. Select a running application in its interface or use a hotkey to apply the change. A user-set application filter helps keep the list focused, and the publisher describes the window changes as reversible to their initial settings.

The utility supports multiple monitors and saves configuration options. Its hotkey can be enabled automatically when Fullscreenizer starts. The linked publisher download is the Fullscreenizer-v1.zip binary archive for version 1.0, whose release notes date the build to 30 March 2021.

The publisher explicitly states that the project is not maintained. Treat it as a legacy utility: this entry does not establish compatibility with every game or current Windows release, and the software has not been installed or tested for this card.

  • Change windowed games to borderless fullscreen.
  • Filter the application list to reduce clutter.
  • Restore fullscreenized applications to their initial window settings.
  • Use multiple monitors and an optional hotkey instead of the interface.
  • Save configuration options and optionally enable the hotkey when the utility starts.

Good to know

  • The publisher states that the project is not maintained; the linked build dates to March 2021.
