Unity config file/or reg key

For windows standalone were does a Unity Build Store its information on what screen resolutions and/or quality settings, inputs, etc store that info? We have it so you can press cntrl while opening unity so it pop ups a screen with the option to change the info. but obviously it must be storing it somewhere??

thanks for any info ;D

The PlayerPrefs documentation details where these settings are stored.

On Windows I see the following settings in the registry that might be what you want:

Screenmanager Is Fullscreen mode
Screenmanager Resolution Height
Screenmanager Resolution Width
UnityGraphicsQuality
