%PROGRAMFILES%\WindowsApps

WindowsApps is a hidden folder where Windows 10 keeps installed apps from the Store.
In contrast, so called System apps are installed under %SystemRoot%\*.
The value of the Environment Variable %PROGRAMFILES% is typically C:\Program Files, thus the WindowsApps directory is located in C:\Program Files\WindowsApps.

TODO

In PowerShell: 
get-appxPackage | select-object name
