You sure have a lot of stupid shit running on your computer to be complaining about multiple instances.
I don't even recognize what half of those things are, and therefore they do not need to be running.
Ok, Mr. Smarty Pants, lets see whats not an essential process that is running on idle.
csrss [win32 console]
lsass [security policy man.]
svchost [instances 7]
system [default system counter]
system idle process [system counter cpu]
winlogon [login logout procedures]
ceepwrsvc [battery monitor]
ivpsvmgr [toshiba software monitor/updater]
acs [network card]
agrsmsvc [sound card driver]
apntex [touchpad driver]
apoint [touchpad software]
dvdramsv [dvd/cd drive driver]
starwindserviceae [alcohol driver]
cdac11ba [copyright protection?]
Well five out of twenty-three processes sure thats close to 11 and a half. Oh wait its not.
Care to open your mouth again?
