"Disable failed No devices disabled" devcon.exe | How to disable devices from command prompt

 This article will help you in Disable or Enable devices from command prompt. And also this will discuss about the error u may likely to encounter.

It will be really good rite, when you can disconnect your modem or internet connection in one click after you are finished with it. This article will help you to do that.

First you need to have devcon.exe. An alternate to device manager which can be run through command prompt.

Download the devcon.exe from the below link


Once you downloaded the devcon exe file, extract  the exe and paste it inside c:\windows\system32 folder. That's it you are ready to run it. 

 I've read the above procedure in a blog, and wanted to try it.  But i was getting this message..

C:\Windows\system32>devcon disable *mouse*
HID\VID_04CA&PID_0030\7&3A7DF96F&0&0000                     : Disable failed
No devices disabled.

After some digging i found the the 64 bit version of devcon available to download form Microsoft website is not compatible for windows 7 64 bit. You will need to extract it from server 2003 64 bit dvd.

Once it's done it will work like a charm. I've extracted the 32 and 64 bit version devcon.exe from server 2003 dvd and uploaded it. You can download it from below links..

Devcon.exe 32 bit

Devcon.exe 64 bit

Hope this helps..

Hi I'm using devcon to disable and re-enable devices in an automated test system. The 1st time i run through, it works great. the 2nd time, it doesn't disable, says reboot required. How do I get around this?

I downloaded the 64 bit version and put it in the system32 folder. shouldn't matter?#
when I run this from the prompt it finds devices but I still get the disable failed back. very annoying.
im using windows 7 professional. any thoughts ? thanks

Trying to get the remove command to work on XP Embedded. File has been copied to the system32 folder but still fails. Does this work on XP Embedded?

Bosshog said...

Received the same message in XP too...not sure what I'm doing wrong

It allows me to disable, but not remove the RealTek driver

thanks a lot man !! problem solved ;-)

Unknown said...

Worked for me..
Thanks a lot..
Wonder why the following didnt work..
Its a code snippet of my visual c++ 2013 project built for x64 bit environment.. Hencee I had to resort to devcon...

params.ClassInstallHeader.cbSize = sizeof(SP_CLASSINSTALL_HEADER);
params.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;
params.HwProfile = 0;
params.StateChange = DICS_DISABLE;

// prepare operation
if (!SetupDiSetClassInstallParams(hDevInfo, &DeviceInfoData, &params.ClassInstallHeader, sizeof(params)))
printf("Error while preparing params !\n");
// launch op
if (!SetupDiCallClassInstaller(DIF_PROPERTYCHANGE, hDevInfo, &DeviceInfoData))
printf("Error while calling OP ! Return code is %x\n", GetLastError());

Problem solved.. Thats wht matters.
