Hello @Андрей Михалевский ,
Universal Windows Platform (UWP) apps (formerly Windows Store apps and Metro-style apps) are applications that can be used across all compatible Microsoft Windows devices, including personal computers (PCs), tablets, smartphones, Xbox One, Microsoft HoloLens, and Internet of Things. UWP software is primarily purchased and downloaded via the Microsoft Store.
UWP is one of many ways to create client applications for Windows. UWP apps use WinRT APIs to provide powerful UI and advanced asynchronous features that are ideal for internet-connected devices.
You may uninstall UWP apps from settings, Start Screen or use Powershell command:
