Back in SCCM 2007 when you installed FEP 2010 it added many features to the SCCM console – Collections, Packages and etc…
Now in SCCM 2012 the FEP is already integrated in the console, but there are no special Collections or Packages.
If you want to install a FEP client on a machine you simply ‘Enable’ the FEP Policy and deploy the policy to the machine – this will install the client. It does it by running a file called ‘SCEPInstall.exe’ which is located in the CCMSETUP folder. This file is pre-downloaded and ready to be installed the minute you enable the FEP Policy.
But what if for some reason you want to uninstall the client? there is no special task for that in the SCCM console.
To accomplish that all you need to do is to run that same file with the ‘/u /s’ parameters.
So, create a package on the SCCM which runs the file with those parameters and that will uninstall the client – just remember to user ‘%SYSTEMROOT%\CCMSETUP\’ in the program definition.
