Microsoft has just released some new bits for Windows Server Insiders and app developers. First, of all, the Windows Server Insider build 19008 build is now available, which brings no new features except that Windows Server Core Container Images Are now 20% Smaller. You can download this new build from the Windows Server Insider Preview download page.
The Windows 10 SDK build 19008 has also been released today, and it can be used in conjunction with the Windows 10 20H1 build 19008 released last week. There are also no new features in this build except some API changes, and you can learn more in the full release notes. To download this new SDK, head over to the developer section of Microsoft's Windows Insider website.
If you’re a “regular” Windows Insider, we hope to get a new 20H1 build with more bug fixes later this week. According to a recent report, the next major update could be completed as soon as December to follow the Azure development cycle.
