What is it?

Is it really necessary to have four of them running at once?
What does it do?

Thanks,
tiny

svchost.exe 920 - Dnscache

Why do you want to get rid of 2 of the processes? Do any of them appear to be hogging your resources? If so, then there is a problem such as a virus. You need all of them running because you need things like DHCP, DNSCache, LmHosts etc. Windows loads them because they are needed and they shouldn't have any effect on the performance of your system.

You can disable services but you still need svchost.exe running to use the services that you need. BlackViper is a good resource for information on services, but I wouldn't necessarily suggest doing exactly what the guide says. I would definitely disable Messenger service and sharing services that aren't needed unless you're part of a network. Other than that though, I would leave everything else alone because most PCs won't be getting a performance hit from having them running.

Yeah if you have 4 instances of svchost.exe running its because programs are using them ... terminating them will bork your program(s). Also be careful what services you disable as that can break stuff also.

Hey EP! All good with me, applying for Microsoft MVP right now, should have done this a while ago.

Notifications don't work, I only found your response by coming back to hunt up some threads, if you want, give me your email address so we can keep in touch easier!

EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there!
