To run a troubleshooter, just click it in the Troubleshooting pane. To quickly find a relevant troubleshooter, you can perform a search from the Troubleshooting window.

The troubleshooter will launch after you click it. Just click “Next” to begin troubleshooting.

Most troubleshooters will run automatically, looking for problems and fixing any issues they find. To prevent the troubleshooter from automatically making changes to your system, click the “Advanced” link at the bottom left corner of the troubleshooter window and uncheck the “Apply Repairs Automatically” option. You’ll be prompted with more information before the troubleshooter makes any changes to your system.

While most troubleshooters run automatically, some troubleshooters will give you options you need to click. For example, the Program Compatibility troubleshooter will walk you through choosing a program that isn’t working properly and changing its compatibility settings. The Incoming Connections troubleshooter will ask you what you’re trying to do so it know what type of incoming connection to troubleshoot.
