PowerShell is probably the easiest way to get rid of preinstalled Windows 10 apps. If you know the name of a particular app that you want to remove, launch PowerShell with Administrator privileges, and remove the app like this:
PS> Get-AppxPackage *bingweather* | Remove-AppxPackage -WhatIf What if: Performing the operation "Remove package" on target "Microsoft.BingWeather_4.20.1102.0_x64__8wekyb3d8bbwe". PS>
Note: remove the -WhatIf parameter to actually uninstall the app. Do not install apps that you don’t know. There may be Appx packages that are required by other apps.
