On Windows 10, you can use the Settings app to quickly reset and repair an app. You may want to use this option when you’re dealing with a problem with an app that came pre-installed with the OS (such as Mail and Microsoft Edge), as well as to fix problems with apps that you acquired from the Microsoft Store.
How to reset apps on Windows 10 using Settings
