Microsoft may sign the RTM as early as December 17. The main reason to be able to make this conjecture is that December 25 is Christmas, and from December 17, Microsoft engineers will start the Christmas holidays. Therefore, signing the official version before the Christmas holiday is also a good choice for Microsoft, otherwise, this new version may have to be postponed until next year. The website also predicts that the latest signing time for Microsoft is January 6, 2020, because according to previous rumors, Microsoft will start to release a new official version around this time.
We have a separate thread for each insider preview release, with the kits, the uup links and all info about that build, and when it becomes official, the thread will change to official. All builds are listed here: [Index] Windows 10 Builds And till @Tito updates it, the remaining ones are listed here: [Index] Windows 10 Builds (Temp Addition)
Half of me wants them to release late so the serious bugs get ironed out. Half of me wants them to release it fast because the whole world is beta-testing anyway.
Well isn't Microsofts plan to release 20H1 now in December/January to insiders? So that in March/April "most" bugs have been dealt with.
