Built-in apps are called provisioned apps. They are scheduled to be installed for each new user that registers on a Windows 8 PC, so you can't uninstall them completely from the Start screen. To do so, you've to use Windows PowerShell command remove-AppxProvisionedPackage
, like so:
remove-AppxProvisionedPackage -package Microsoft.BingTravel_1.2.0.145_x64__8wekyb3d8bbwe -online
That would uninstall the Travel app. To remove Bing Map app, the command would be:
remove-AppxProvisionedPackage -package Microsoft.BingMaps_1.2.0.136_x86__8wekyb3d8bbwe -online
Microsoft.BingMaps_1.2.0.136_x86__8wekyb3d8bbwe
is the app package name, which basically is the folder that you find in C:\Program Files\WindowsApps
.
To uninstall apps installed from the Windows Store, the command is Remove-AppxPackage
. It's syntax is as below:
Remove-AppxPackage PackageFullName
Note: Do not add -online
parameter at the end of this command. [source]
