For some reason, out of nowhere all the programs in my computer started lagging. So I crtl+alt+del and I see this which is taking up alot of CPU. I tried ending the process but it says the operation could not be completed, the operation is not valid for this process. I tried shutting down and restarting my computer but its still there. How can I fix this? There is also something called mpservic.exe that seems to be taking quite a bit of CPU too, like 20-40.
