Overall, this cumulative update for Windows Server 2019 and Windows 10 Enterprise LTSC 2019 appears to address several important security and quality issues. The known issue with Japanese character rendering in PowerShell on Windows Server 2019 is a notable problem, but Microsoft has provided workarounds until a permanent fix is released. While the update resolves some significant bugs, the presence of known issues means that caution should be exercised when deploying it, especially on mission-critical systems. Thoroughly testing the update in a non-production environment before a wider rollout is advisable. Users experiencing problems after installation should work with Microsoft support to troubleshoot and resolve any issues.
Known Issues
- Japanese characters fail to render correctly in PowerShell on Windows Server 2019 installations. This is caused by an unintended change to PowerShell encoding settings after the update is installed.
