Hello，

• Currently, hotpatching is in preview and is being tested exclusively on Azure. At this time, the functionality is not available for non‑Azure (on-premises or other cloud) deployments.

• Because this feature is in preview, there is no public hotpatch binary available through Windows Update or other standard channels. It is only distributed as part of the preview builds to organizations enrolled in the appropriate insider or preview programs.

Hi @Anonymous ,
Thank you for the Answer
But I have another follow up Question :
I checked the February 11, 2025 Hotpatch (KB5052105) page. Could you confirm if my understanding is correct?

Is Windows Server 2025 Hotpatching generally available for public for environments running in Azure?

Is Windows Server 2025 Hotpatching still in preview only for Azure Arc deployments?

Based on the latest updates (including KB5052105 from February 11, 2025), your understanding is correct:

• For environments running directly in Azure, Windows Server 2025 Hotpatching has reached general availability and is now supported in production.

• For environments managed via Azure Arc (or other non‑Azure deployments), Hotpatching remains in preview. That means if you’re running Windows Server 2025 outside of Azure (for example, on‑premises or in other clouds using Azure Arc), the feature is still under test and not yet generally available.

Keep in mind that because these statuses can change over time, it’s always a good idea to check the most up‑to‑date Microsoft documentation or announcements for the latest details.
