My Windows 7 comp recently started running much slower and chewing up heavy memory (nearly 4 gigs) consistently. I also noticed that there is a process "WmiPrvSE.exe" using between 20-30% of my CPU for no apparent reason. Additionally there seems to always be a svchost.exe process using about 150 megs of memory at any given time and another dozen or so svchost.exe processes running just for fun. Maybe thats normal but it seems out of the norm. Not sure if this is just standard Windows genius at work or if I have reason for concern. Any advice would be greatly appreciated. Thank you
