That's the latest Windows Insider Dev Fast Channel build and we only support Released versions of Windows 10.


Also, if you are at all familiar with Insider Builds, you know you should NOT be using 21H1 Dev Fast Channel builds on any PC that you need to be reliable to do useful work.


For details about Insider Builds and their issues (and they ALL have them) read the threads on this forum:  (9) Windows 10 News - Windows 10 Forums (
