My computer started to lag tonight and my CPU useage is showing at 100%, sometimes down to 70, sometimes 90%. At one pt the larger program use was wcault.exe I think, which I looke dup and sai dit was windows update. I dont see windows update int he system tray though? I closed that from the running processes, now it is just winword and outlook that show up at the top when I sort by largest. Nothing seems out of the ordinary. But CPU is still 100%. I am concerned! Thanks.
