You can enable SCCM to uninstall a Windows sensor.
On the Programs tab in SCCM, if the Require code to uninstall sensor is enabled for the sensor policy and you want to uninstall the sensor using SCCM, change the uninstall command from msiexec /x"installer_vista_win7_win8-xx-x.x.x.xxxx.msi" to %ProgramFiles%\Confer\uninstall.exe /uninstall <Company Deregistration Code>.
