>>>Yesterday my office machine was working fine. This morning I accessed it from home. It had restarted after Windows automatic update overnight. Now CPU usage is 100%, hardly any of it in System Idle Process. It's worst when iexplorer is running (40-60% of CPU usage). Windows task manager takes a bigger chunk than usual. Forget about doing useful work.

>Thanks for the Tracy. I will check both places. The processes using the most CPU are iexplorer and task manager. After I close iexplorer from the task manager, system idle goes back up to about 65%; still a small number considering I am doing absolutely nothing useful. Something is living in iexplorer, I fear. I am staring up Process Explorer to see what it says.

I've actually had that happen before. When you do this it will close all of your open internet explorer pages (including the UT). It should clear it up though. End the iexplorer processes and then go back to the UT>
