I came pretty aware of everything I had on my old laptops task manager and programmes. When I bought my current laptop though it came with lots of programmes and software already installed. I wish to remove all unrelavent programmes and software not needed, but I'm not quite sure what it what.

igfxext Module
igfxsrvc Module
igfxTray Module
(These appear in my task manager does anyone know what they are? When I close them it doesn't seem to change any performance or pysical status.)
