New to Vista + Clean Boot = ?

Ok, so I'm fairly new to vista I admit, but I'm curious. How would I go about running a 'clean boot' scenerio on my new XPS laptop so that I can get everybit of power out of this thing that I can? I just don't think I can get everything out of it when its running upwards of 60-65 processes. I'm looking at having a 'gaming' user that when logged into has only necessary processes running to effectivly play games. Thanks for the help!

Dell XPS 1530
C2D T9300
4Gigs of Ram
120Gig 7200 RPM HDD
8600M GT graphics

If it's an OEM install, try PC Decrapifier to get rid of the unwanted OEM preinstall garbage.

Hm. Well thats the thing, under normal boot up everything thats there I want to keep. Stuff for blue tooth, the camera, etc etc. And even playing Fallout 3 on high settings is smooth, but I want to kill the unnecessary so that I can push performance even further during game play.

If you are familiar with Windows operating systems, things are still the same.

Uninstall all the assorted google and company crap Dell ships to you.
Go into your startup and clean out anything that you don't need to startup with your system. Change your power settings under "Screensaver" to "high performance". Disk cleanup and defrag (Although Vista says it does it automatically).

Also, hit Dell's site to get your boards drivers and hit either Nvidia or ATI's site to get your video drivers. Hit Intel or AMD site to get optimization software. Lastly, avoid using Microsoft released drivers for your video card.

Go to a "Run" command and type "msconfig". This will allow you to clean up your startup items. You will be surprised how much crap Dell shoves your way.
