uninstalling Lenovo ThinkVantage software

[Marin85]

Hi,
slowly but surely the amount of software on my laptop increases, so I want to uninstall some components of Lenovo ThinkVantage software as I can´t "give away" some other very essential programs for my work. Does anybody have a good idea which parts of Lenovo ThinkVantage software package are safe to be deleted? Is it possible to use the fingerprint reader without CSS? If I uninstall R&R, could I then stil use the preload R&R work area case something goes wrong and if yes how far?

Thanks in advance

M.

P.S. I would keep PowerManager, UltraNav, APS and UpdateManager and see what will happen then
