Windows 8/8.1 app distribution ends in 2023
 

As a part of our Windows device life cycle, Microsoft Store will soon stop accepting new apps with Windows Phone 8.x or earlier or Windows 8/8.1 packages (XAP and APPX). Soon after that date, we will stop distributing app updates to Windows Phone 8.x or earlier and Windows 8/8.1 devices; at that time, updates will only be made available to customers using Windows 10 devices.

Application distribution to Windows 8/8.1 will cease 31 July, 2023.
