Ta for all the replies.
I'm just used to having a finely tuned machine and this is the 1st time i've used Windows 7. I don't see the point of having services and programmes running in the background that are of no use to me hence why I want them turned off. Just a bit iffy about these things that's all.
I don't see why I have to have 41 things running in the background while i'm running no programmes and i'm just on the desktop.
Windows 7 is already very efficient. Services that appear to be running are likely to be using next to nothing in terms of resources and will have zero impact on your gaming/editing/porn.
There are services you can disable if you know you don't use that feature - such as HomeGroup, but generally it is better not to meddle. As I said previously, you have far more to lose than you could possibly hope to gain.
