I want to be able to start Fortnite windowed before launching so I'm assuming there will be a setting in a local file somewhere that tells the game if it should launch fullscreen or windowed but I can't find it.

How do I launch the game in windowed mode?

Note: I do not want answers telling me to change a setting once the game has already launched.

    @KevinTheGreat To do it in settings I have to launch the game, if I have the game in full screen my remote viewer doesn't show it so I can't change anything. Jun 4, 2018 at 10:12

Mine opens in windowed mode by default when launching.

My setting are:

Windowed mode: Windowed

Display Res: 1680x1050 16:10

No changes have been made, this may be a change since the season 4 update as it never used to do this


The Windows operating system supports command-line switches to adjust certain start-up parameters of programs. One way to "force" Fortnite to run in a windowed mode is to create a special shortcut to the games's main executable, then configure that shortcut with the applicable command-line switch.

  1. Create a shortcut for Fortnite on your desktop (if you haven't already)

  2. Right click the shortcut.

  3. Select properties

  4. In the Shortcut tab, in the Target: field, add -window or -w at the end of the file path.

  5. Click OK or Apply then OK

Hope this helps.
