Your system seems sluggish, so you open Task Manager, select the Processes tab, click Show Processes From All Users, and observe that one of the svchost.exe processes consumes a lot of CPU for long periods of time. What can you do? Here's a quick and dirty way of troubleshooting the problem which may be useful to try if your system isn't mission-critical to your business:
- Right-click on the problem svchost.exe process and select Go To Service(s). This will switch you to the Services tab and will highlight all of the services hosted within the svchost.exe process.
- Right-click on one of the identified services and select Stop to stop the service. Switch back to the Processes tab to see if the CPU usage has dropped to normal.
- If the CPU usage remains high, repeat the above two steps until you have identified which service is causing the problem.
- Open a command prompt and use the sc config command to isolate the problem service into its own svchost.exe instance. Now you can simply kill this svchost.exe instance should the problem ever occur again.
