We can download both the full March Cumulative Update or there is now a Delta available.
Delta Update Windows Server 2016
The update is quite critical for those of us that run clusters on Windows Server 2016.
- Addresses issue which could cause ReFS metadata corruption
- Several fixes for Enable-ClusterS2D cmdlet for setting up Storage Spaces Direct
- Addresses issue with Update-ClusterFunctionalLevel cmdlet during rolling upgrades if any of the default resource types are not registered
- Optimization to the ordering when draining a S2D node with Storage Maintenance Mode
- Addresses servicing issue where the Cluster Service may not start automatically on the first reboot after applying an update
- Improved the bandwidth of SSD/NVMe drives available to application workloads during S2D rebuild operations.
- Addresses issue with all flash S2D systems with cache devices where there was unnecessary read data from both tiers that would degrade performance

The Delta Update can be used to update our .WIM files for our Windows Server 2016 flash drive based installers (Blog post How-To).
Note that the last Cumulative Update took a good hour to run on our VMs and nodes. This one is sounding like it may take as long or longer depending on whether the Delta of full Cumulative Update gets installed.
Here’s a direct link to the Microsoft Update Page for KB4013429.
Happy Patching! ;)
