Announcing Windows Server 2019 Insider Preview Build 17677

Hello Windows Insiders!

Today we are pleased to release a new build of the Windows Server vNext Long-Term Servicing Channel (LTSC) release that contains both the Desktop Experience and Server Core in all 18 server languages, as well as a new build of the next Windows Server Semi-Annual Channel release in English.

There are two major areas that we would like you to try out in each preview release and report back any issues:

Build-to-build upgrade is currently not supported.

Container Improvements

In our continued effort to improve Windows Server Core and reduce its image size, we made the following changes: – we converted non-critical font components into optional components (OC) in Windows Server Core editions, and then removed these OCs from Windows Server Core container images. This change won’t affect the user experience of Windows Server Core, except that users now have the ability to enable or disable non-critical font components, like they can do for any other OC. For Server Core containers, only the default font, Arial, is supported; no other fonts are supported, and no others can be installed.
