On my laptop, I use it for two purposes: as a media player for my TV and also for playing live music at gigs. For the music gigs, I really need to make sure there are no extra things running on the computer and the resources are as free as possible. For media, it's the opposite, where a whole slew of things are running. If I create a different login, can I customize which services I run on each login. If I disable a bunch of services in one profile, it doesn't affect the other login, does it?
