question regarding the comand related with devcon

Hi All,

In Devcon list of commands we have a method to install a class filter using the command classfilter

devcon /r classfilter Keyboard upper +Keyfilterdrv

And actually adds the filter to the keyboard class…Now how to i remove or uninstall this classfilter which is added ???

Is there any provision to remove the class filter ?

Did you even look at the devcon help information?
devcon classfilter keyboard upper !keyfilterdrv

The question I’ve never understood is why devcon doesn’t have an
equivalent function for device filters.

Device filters should be altered with an INF install.
