Can you help us understand the OS breakdown of the 20K servers? Are the majority of them WS 2025? Is connecting to Azure Arc not an option? 

Hotpatching for on-premise is limited to WS 2025 servers that are Azure Arc connected.

Connecting to Azure Arc for License Count/Measurement would be ok for us (also if it would be better without the Azure Arc Connection Requirement, after you announced today that Hotpatching will be free for W2k25 anyway). We know that Hotpatching is limited to W2k25.
