Paul Thurrott has a tip for uninstalling built-in Windows 10 apps. CCleaner, a Windows registry cleaner for years, now has the ability to uninstall apps that Windows doesn't normally let you uninstall.
If you just want to repair an app that isn't working, then you can simply remove the app with CCleaner and re-download it from the Windows app store. Get CCleaner for Windows at piriform.com/ccleaner.
