Many Windows users know that control panel applets can be called from the Run line. For example, using the syntax below will call up the Regional and Language Options applet.
control intl.cpl
However, there is more to it than that.
For an applet like main.cpl which serves multiple purposes, you can use a command line parameter – @# – where # is the zero-based number of the tab you want it to open at. For instance, @0 will open the mouse control applet, @1 will open the keyboard control applet.
control main.cpl,@1
If you want to open the applet with a specific tab open, there's another parameter you can use. Use the zero-based number of the tab you want it to open at. For instance, the following run line will open the mouse applet with the third tab (pointer options) open. Remember, it's zero-based, so we use 2 for the third tab.
control main.cpl,@0,2
