"Live Tile" is an interface that was originally adopted in Microsoft's mobile terminal OS Windows Phone since 2009, and was incorporated in "Windows 8" released in 2012. It is a function that allows you to display the contents inside the start menu without starting the application.
Unfortunately, the name of "Windows Phone" disappeared as support for the final version "Windows Phone 8.1" ended in the summer of 2017. Support for the successor OS “Windows 10 Mobile” ended at the end of 2019, and the genealogy was discontinued.

For this reason, Windows 10 live tiles were one of the few "legacy" reminders of the existence of Windows Phone to users.
However, it seems that there are not many users who are using it, and there are rumors of its abolition.
In addition, it was discovered that the preview version of the "Windows 10 20H1" update, which is scheduled to appear in the spring of 2020, has disappeared the live tile from the start menu.

In the news site WindowsLatest, as information from detailed sources, it is revealed that after the release of "Windows 10 20H2", further updates will replace live tiles with icons. "Plans may change, but most users don't use live tiles, so no one will be surprised if they disappear."
