I upgraded this particular computer about three weeks ago. Things have been running fine until today. The user called and said it was running extremely slow. When I got on and looked in task manager it was pulling a constant 50% CPU utilization but it wasn't any one process. I have never seen anything like it. There were about 40 processes and each one was running a constant .8% (some were a tad higher).
SFC did return a few corrupt file and DISM is running now but has anyone seen anything like there? Where several processes at running a constant 1%? Malware scan did not come up with anything.
