Microsoft Windows 10 Troubleshooting Tool can identify and fix many issues automatically. The troubleshooter will attempt to detect and automatically repair any found issues. If it can't identify the problems you're having, you can choose to explore additional options or just close the troubleshooter. You can also view a troubleshooting report which will tell you what issues were checked, and the findings.

Click the small Advanced link on the opening screen and you'll be able to uncheck the automatic repair option if you'd rather the tool just reported on found problems.
