Can anyone give me a brief explanation of this? For the life of me I cannot understand the technical explanations I find when doing a Google search. I've always taken it for granted that you need Windows Management Instrumentation enabled, and set to "automatic" in Services. Even blkviper recommends keeping it set to automatic (and he disables just about everything). However, SiSoft Sandra suggested I shut it off as one of its tips peculiar to my system. So I did. So far I've experienced no ill effects. So what gives with this service? Do you need it or not? Is there a comprehensible description for it for dummies like me? Does it have anything to to with the "wbem" folder in WINDOWS?
