Too many processes.

I've recently just got vista and I've noticed is ridicolous demand for processes. Its quite concering because i've noticed my PC has become more louder and sounds like its trying harder. Its only a month old but doesn't sound like it at all. Here is a screenshot of the ones that I've got when im using my normally (second one is the rest of them from the highlighted one down).

I've turned a few things off in startup and I spoke to a friend who uses the same version of vista which is 32bit that he has got his processes down to 30, this is when he has his normal stuff running. Any ideas on how to cut them down? Thanks.

First thing you need to do is know what the processes are and what other services depend on them to run, if any at all.

Try going to your services in admin tools or type services.msc into the search bar. Here you will find sometimes vague, but usually thorough explanations of their purpose. If you aren't satisfied with the explanation then try googling and gather a consensus of explanations to ensure whether you do or do not need it.

Right click on one of the services, scroll to properties, and click the 'dependencies' tab. There are two sections that indicate what services depend on the one in question and the services that your given one depends on to run properly.

Msconfig is useful in its own ways to quickly identify start-up programs, but not a place (I don't think), to alter services.

In the 'general' tab of msconfig check the 'diagnostic start-up' and reboot. Upon reboot go to services.msc and print.(make sure the spooler service is enabled for print)

Check your task manager and note and identify the types and amount of processes. Print...

Go to msconfig/general again and now check 'normal start-up'. Reboot.

Repeat the steps above and identify the contrasts. It is important to clearly define and grasp the role of the contrasting processes. Then you are free to manipulate it how you see fit based on your needs and set-up.
