Troubleshooting options are part of Windows Recovery Environment. They allow you to repair your Windows installation, remove unwanted drivers, enter Safe Mode and so on. In Windows 10, Microsoft has added additional options which allow you to reinstall the OS and also remove unwanted updates.
Windows Update is a very important component of Windows. Microsoft uses this service to redistribute security patches, add new features and improve the user experience and the performance of the OS. But sometimes these patches can break the OS and prevent it from booting. If a regression occurs, the option to remove the problematic update from the recovery environment is extremely handy.
