"Doesnt hog the CPU like others"
It is quick to install and very quick start ups when first turning the computer on.Others I have tried take ages to load the system.It doesnt hog the CPU "when Im using" the computer.Updates are quick to install too.
It hogs the CPU (100% )when my system has been idle for at least 15 mins.Once I move the mouse or do something it will quit using CPU,however, the system seems sluggish afterward with anything I do as if Ive just used a very intensive program so have to restart the comp for the lagging to go away.I found it was a process called 'MsMpEng.exe' that was the culprit which is associated with MSE.I have found others to have similar problems so Im guessing its more a bug within the program.
I am using MSE on Windows XP Pro(SP3).Overall it has been an ok experience with the one exception.
