I agree 100%. Service tweaking saves a lot of memory and other resources. There are A LOT of services running that you actually never need (depending on what kind of computer you have - gaming, working, networking, multimedia, etc). It also stays cleaner for a long time.

Whatever happened to Blackvipers site? That had the best info of the sites that covered Windows Services.

There once was an article which did analyse the real performance result of service tweaking and there was absolutely no improvement but I agree that really useless services whould be disabled ... but in case where your are not 100% sure ... leave it default
