Microsoft releases build 20257 on the Insider Dev Channel

A new build is coming to the Windows Insider Program Dev Channel. A small update that only changes the development branch and fixes many of the current problems in Windows 10. More specifically, we are talking about FE_Release Build 20257, one of the multiple development branches they have within Microsoft right now, and not I know it doesn’t match any specific version.

Happy # Veterans day and thanks to those who served!

Updates for developers

As with every build, we have a new Windows SDK in the development channel. Whenever a new OS build is created in the dev channel, the corresponding SDK will also be offered. You can always install the latest version of the Insider SDK from aka.ms/InsiderSDK. The SDK versions will be stored in Flight Hub along with the OS versions.
