@nycki96 @munchkinbear @mcourcel @MariahL @SeveraSnape @FreakyFwoof UWP stands for Universal Windows Platform, and it was used for developing apps that would run on both Windows 10 and Windows 11. It is no longer under active development, and so app developers are being asked to migrate their apps to WinUI, which allows for complete integration with things like the new Win11 context menus and other features like that. In cases like Spotify, Whatsapp, Telegram and similar, where apps need to work across platforms and it's cost-prohibitive to have developers and project managers ETC. who can develop a native app for each platform, (Windows, Mack, iOS, Android, ETC.), you build one app for the browser and you wrap it in something so it can run on all the things. In this case, the browser for the apps is Edge, which is still a resource hog. Deprication means that something has been retired and is no longer supported, and it typically referrs to functions or code libraries ETC.
