Recently, Microsoft has confirmed that it will switch the fast channel members to the active development branch (called RS? Prerelease). This means that the version updates received by windows insider members of fast channel will no longer follow the "twice a year" windows 10 function updates, but reflect the current development status.
Although the app doesn't provide any useful information in the description, it uses the same "download" icon as the one used to set up the app's "about" section. And the windows feature experience pack is now displayed under the windows specifications of the settings application. And the version number is different from the system version, which is build 19536.1000
In a tweet, Walking Cat said Microsoft will make major changes to the shell features distributed to users, and it looks like Microsoft will provide a separate Shell experience. This means that companies may be system-independent, make it easier to add / remove new features and improvements, and do not need to launch blockbuster operating system updates.
At present, the technical details and specific launch time of this work are not clear. But the news is true, which means Microsoft can separate windows core OS and shell experience. In this way, without major system updates, Microsoft can provide consumers with new functions faster. This may also mean that windows 10 may get a condensed version with additional features.
