There are three steps in uninstalling CTFMON.EXE as described in Frequently asked questions about Ctfmon.exe

Step1: Uninstall Alternative User Input
Step2: Remove Alternative User Input Services from Text Services
Step3: Run Regsvr32 /U on the Msimtf.dll and Msctf.dll Files

Step1 is easy because it can be done when creating your Unattended.MST for MS Office, using ORK tools. Step3 is also easy because it's a simple batch file which can be executed after the office installation. My problem is, how do I unattendedly execute Step2? Especially when it says that the only input service that should remain installed is "English (United States)- default Keyboard United States 101", and i also want to have Greek installed, as displayed in the following picture.
