Windowed[edit]

Edit config files^{[citation needed]}

Go to the configuration file(s) location.
Open settings.txt.
Change fullScreen=yes to fullScreen=no

Notes

If you encounter mouse cursor issues in windowed mode, try the borderless fullscreen windowed fix, making sure to disable the borderless option as instructed.

Borderless fullscreen windowed[edit]

Attempting to force borderless windowed mode using an external application will cause issues with the mouse cursor. This fix avoids those issues, and can also fix the cursor in non-borderless windowed mode.

Use dll patch^{[citation needed]}

Enable windowed mode.
Download the v2winfix.
Extract dinput8.dll into the game installation folder.
Borderless fullscreen windowed mode is now enabled, but can be disabled in %USERPROFILE%\Documents\Paradox Interactive\v2winfix.ini, by editing the line borderless=1.

Notes

Only tested with patch versions 4.02 and 3.05.
