Apart from ffdshow which is a video codec, (And may be needed by other programs) the rest can be un-installed as they are just taking up resources and providing no benefit.

You will find them in the programs and features in the control panel, at the same time un-install any other programs you don’t need.

TIP: When loading programs onto the computer use the custom option (Instead of the easy option) so that you can decide what to install. (A lot of programs install other programs without telling you except in the small print and custom gets round this)

Hope this helps
