Start Sims 4 in Windowed Mode

Method 1

  1. Start Origin and Login
  2. Find the Game in My Game Library
  3. Right-Click on the game and choose Game Properties
  4. Click on the Tab Advanced Launch Options
  5. In the field under Command line arguments write -w and press Save
  6. Start the game
  7. After starting the game you can set the desired setting in the game and then remove the setting in Origin.

Method 2

This method only works if the game was already started once and the user folder has the file needed.

Sims 4 has three different Display Types: Fullscreen, Windowed and Windowed-Fullscreen. You can set the mode directly in the Options.ini file

How to manipulate the options.ini file
  1. Make sure the game is closed
  2. Navigate to your user folder in the file system and find the file Options.ini. If you have known extensions hidden you will only see the file as Options.
  3. Right-Click on the file and choose: Open with and then Editor (you can use any text editor of your choosing).
  4. Change the desired options
  5. Save your changes. Make sure, Windows doesn't add a txt as extension. The file needs to say an ini file and needs to have the corresponding icon.
  6. Start the game.
  1. Look for the following entries in the file: fullscreen = and windowedfullscreen =
  2. Change the value as follows:
    • Fullscreen: fullscreen = 1, windowedfullscreen = 0
    • Fullscreen-Windowed: fullscreen = 1, windowedfullscreen = 1
    • Windowed: fullscreen = 0, windowedfullscreen = 0
