control.exe is Wine's implementation of the Windows Control Panel.
wine control [filename.cpl | COLOR | DATE/TIME | DESKTOP | INTERNATIONAL | KEYBOARD | MOUSE | PORTS | PRINTERS]
Note: Wine does not currently implement many of the control panel applets (.cpl files) typically found on a Windows system. If the requested applet cannot be found, it will silently exit. It should however be possible to load applets installed by third party software by running "wine control" and clicking the appropriate icon or specifying the .cpl file on the command line.
