Command line to "Close Control Panel Applet"?


I would like to know if there is a way to "close" an open Control Panel Applet via a command line reference?I know a couple ways to open the window -

"c:\windows\system32\mmsys.cpl" OR command mmsys.cpl

but I would like to also close it via command line. Any suggestions?

Enter taskkill /? from a Elevated Command prompt. That is one way.

I tried that to no avail, but maybe my syntax is bad --

control taskkill /F /IM mmsys.cpl

That is one way.
taskkill /im rundll32.exe
But it's not so safe if there happens to be other Rundll32 processes running.

A safer method would be to use a bit of VBScript.

Set objShell = CreateObject("WScript.Shell")
> "%TEMP%\tmp_%~n0.vbs" (
	echo Set objShell = CreateObject^("WScript.Shell"^)
	echo objShell.AppActivate^("Sound"^)
	echo objShell.SendKeys^("%%{F4}"^)
WScript "%TEMP%\tmp_%~n0.vbs"
del "%TEMP%\tmp_%~n0.vbs"

REM Same as the above but on one line:
(echo Set objShell = CreateObject^("WScript.Shell"^)&echo objShell.AppActivate^("Sound"^)&echo objShell.SendKeys^("%%{F4}"^))>"%TEMP%\tmp_%~n0.vbs"&&(WScript "%TEMP%\tmp_%~n0.vbs"&del "%TEMP%\tmp_%~n0.vbs")
Command Line command
(echo Set objShell = CreateObject^("WScript.Shell"^)&echo objShell.AppActivate^("Sound"^)&echo objShell.SendKeys^("%{F4}"^))>"%TEMP%\tmp_CloseSound.vbs"&&(WScript "%TEMP%\tmp_CloseSound.vbs"&timeout 1 >NUL&del "%TEMP%\tmp_CloseSound.vbs")
Note that these solutions make use of temp files.

Excellent - thank you very much Pyprohly. The batchfile is exactly what I was looking for - works perfectly.

Thanks again....

One other way is to search for the PID of the rundll32.exe instance that is running the mmsys.cpl module
tasklist /M mmsys.cpl /FI "IMAGENAME eq rundll32.exe"
then you can safely kill the correct process using taskkill

taskkill /F /PID <pid>
