Microsoft Announces Windows Server 2019 Insider Preview Build 17677

Microsoft announced the release of a new build for Windows Server vNext Log-Term Servicing Channel (LTSC) release which contains both the Desktop Experience and the Server Core in all 18 server languages. With this, the company has launched a new build of the next Windows Server Semi-Annual Channel release in English.

The two major areas that Microsoft would like you to try out in each preview release and report back any issues are as given below:

  • In-place OS Upgrade (from Windows Server 2012 R2, Windows Server 2016)
  • Application compatibility – please let us know if any server roles or applications stops working or fails to function as it used to

The build-to-build upgrade is currently not supported.

New features in this build:

Performance history for Storage Spaces Direct

This build brings better history feature of Storage Spaces Direct as per the official blog:

The Get-ClusterPerf cmdlet now includes self-diagnosis logic: if the cmdlet finds nothing to report, it now looks for common issues that would prevent performance history from working properly (for example, if its storage is missing) so that the cmdlet can provide clear error text.

New cmdlets, Start-ClusterPerformanceHistory and Stop-ClusterPerformanceHistory, that are provided in this build make it easy to remediate such issues by cleaning up and/or re-provisioning performance history.

New series, provided in this build, record how much Storage Spaces Direct data needs to repair/resync per server.

Container Improvements

Microsoft is continuously making effort to improve Windows Server Core and reduce its image size, and hence the came up with the following changes: –

The 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, however, will not 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.
