As it typically does on Tuesdays, Microsoft has released a new build of Windows Server to users in the Insider program. The build number 19608, the same as last week's Windows 10 build in the Fast ring. This release follows up on last week's build 19603, which was released without a blog post.
If you were thinking things would be different this week, that doesn't seem to be the case. As of right now, there's no blog post for build 19608 of Windows Server, so it's anyone's guess as to what's changed since the last build, or even the one before that. If Microsoft does share a changelog this time, we'll update this article accordingly.
Another thing that often happens on Tuesdays is the release of new preview builds of the Windows 10 SDK. This week, this is also getting bumped to build number 19608, but that release also comes without a blog post to detail the changes. It's been a while since the last SDK Preview release, so there may be some notable changes this time around, but there's no way to know for sure. There are also accompanying builds of the ADK and WDK previews.
If you'd like to download the latest Windows Server Insider Preview build, you can do so here. For the Windows 10 SDK Preview, you can get build 19608 here, as well as the corresponding builds of the ADK and the WDK. The HLK hasn't been updated since build 19041, which is still from the 20H1 development cycle.
