Today, Microsoft released a new Windows Server Insider Preview, bringing the build number to 18995. As usual, the build number aligns with last week’s client Insider Preview in the Fast ring.
While it’s described in the blog post as ‘vNext’, it’s actually from the 20H1 development branch, so it’s not actually the next version of Windows Server. The next version of the OS is 19H2, and Microsoft hasn’t offered any previews of that. Like the client update, Server 19H2 will focus on fixes and reliability.
As for today’s build, there are no new features listed in the blog post. There is one known issue, which has been listed for some time now:
There is an issue where the App Compatibility FOD cannot be added to the OS .wim image offline using DISM /image method. After upgrade, it is necessary to reinstall the new FOD using DISM /online method.
