What is an idle OS? You're retarded. Sorry. Has to be said.
An operating system's job isn't to waste your resources. Every operating system idles. Unfortunately, while Vista idles, it likes to waste CPU cycles and cache junk in memory.
Now dont get me wrong, caching things in memory is sometimes a very important job for an OS to do. Vista just does it wrong.
Lucky for me there's a few hundred people that'll call you something other than n00b right about now, so no worries.
If you're not clear on how Vista works and why, that's fine, but don't go making off-the-cuff remarks, especially when you have no clue about the history of Vista discussions around here, which is dreadfully apparent at this point.
Keep the personal attacks to a minimum lest the mighty Mods lay the smackdown on ya...

Man that's classic, and so funny I simply had to repeat it and even add em-faaaaaa-sis. I should add that to my sig.
