Windows 10 Bizarre RunDLL Error in shell32.DLL

I have a new (~month old) HP Envy 17" laptop computer running Windows 10.  When I attempt the following, I get a bizarre RunDLL error in shell32.dll:

     rundll32.exe shell32.dll,control_RunDLL ncpa.cpl

The bizarre error is as follows:

     RunDLL     Error in shell32.dll

     Missing entry: control_RunDLL

I selected Install as the Windows Topic for this query because I don't know where it actually fits.  I figured either I have a syntax error or there may be something wrong with the OS installation.

Please help.  Thank you.

    Wow. Thanks for reminding us about case sensitivity. It's already easy to get syntax wrong if it isn't copied/pasted, but that makes it even more important.

    Greg,

    Mea Culpa!

    Problem resolved!  It did turn out to be a syntax error (case sensitivity).

    The command line: rundll32.exe shell32.dll,control_RunDLL ncpa.cpl 

    should read rundll32.exe shell32.dll,Control_RunDLL ncpa.cpl 

    I am relieved that there is no apparent issue with my Windows 10 installation!

    Thanks again.

    Greg,

    I should correct one item from a previous message detailing the computers on which I have run into this problem.  I mentioned that my previous computer was 6 years old as it was purchased in 2012, but actually it is just over 5.  It was purchased in late 2012 and was delivered with Windows 8 - subsequently upgraded to Windows 8.1 and then to Windows 10.

    My wife's Surface Pro 2 was also upgraded to Windows 10, and my current computer was delivered with Windows 10.  So, the bottom line is that all three are running under Windows 10 Pro - in case that may make any difference to this problem.

    FYI, my friend's computer, on which this command line runs properly, is also running Windows 10 Pro, making my concern over the syntax even more baffling.

    Greg,

    Because of all the things I do on my computer, I need several USB ports.  In an effort to reduce the requirement by one, I purchased a Microsoft Bluetooth mouse, eliminating the wireless mouse mini dongle.

    There are often times when I am doing things, such as running a security scan, et al, when I prefer to take my Wi-Fi connected computer offline.  However, I still want the mouse to function and the now-called Airplane Mode not only disables the network but also the Bluetooth; so, I am trying to create a shortcut that I can pin to the Start Menu that will allow me to disable the network without disabling Bluetooth.

    Regardless of what I am attempting to do, I have friends on whose computers the command does work - indicating something is amiss at my end.

    The command: rundll32.exe shell32.dll,control_RunDLL ncpa.cpl  is intended to bring up the network connections window so I can disable and re-enable the Wi-Fi.

    Thanks.

    What is the purpose of the command you're running? What did you expect it to reply?
