Microsoft is preparing to move forward with its testing of its next Windows 10 feature update. And, in a number of key ways, it won’t be following the playbook it established in previous years with its Insider program.
On December 16, Microsoft also released what officials said would be the last test flight of calendar 2019. Build 19536 is the first Fast Ring test build from its active development branch. Microsoft is not saying if this new build will become Windows 10 20H2 or Windows 10 21H1. In fact, officials said the code it’s releasing today actually might not end up in either of those updates.
