Recommendations
- Pause updates if this machine is doing deadline-sensitive or production work.
- Check Microsoft's known-issue and safeguard-hold list for this KB before installing.
- Keep the uninstall path in mind: a cumulative update can be removed from Settings > Windows Update > Update history for a limited window after installation.
Current reports mention update/install failure in windows update, boot failure in startup / boot, display regression in display / graphics.
