How does hotpatching work?

Hotpatching is a new way to install updates in Windows Server 2025 that does not require a reboot after installation, by patching in-memory code of running processes without the need to restart the process, the application, or operating system.

Some of the benefits of hotpatching include the following:

• Greater uptime with fewer reboots, instead of rebooting monthly (12 times a year) rebooting is reduced to quarterly (4 times a year).
• Faster deployment of updates as the packages are smaller, install faster, and have easier patch orchestration with Azure Update Manager (optional).
• Hotpatch packages install without the need to schedule a reboot, so they can happen sooner. This decreases the “window of vulnerability” which can result if an administrator might normally delay an update and restart after a Windows security update is released.

Azure Arc-enabled Hotpatching for Windows Server 2025 is available for a subscription of $1.50 USD per CPU core per month. 

With hotpatching, you will still need to restart your Windows Servers about four times yearly for baseline updates, but hotpatching can save significant time and ease the inconvenience of a traditional “patch Tuesday.” 

Hotpatching for Windows Server Datacenter: Azure Edition has been available for years. In fact, our own Xbox team has used it to reduce processes that used to take the team weeks down to just a couple of days. With Windows Server 2025, we have been able to deliver these efficiencies to on-premises and non-Azure servers through connection with Azure Arc.

What are the requirements?

To use hotpatching outside of Azure such as, on-premises or in multicloud environments, you must be using Windows Server 2025 Standard or Datacenter, and your server must be connected to Azure Arc. You will also need to subscribe to the Hotpatch service.

Important reminder: If you are currently using Windows Server 2025 and opted in to try the hotpatching service through Azure Arc in preview, you will need to disenroll if you wish to end your preview and not subscribe to the service. Otherwise, your subscription starts automatically in July 2025.

If you’re running on Azure IaaS, or Azure Local you can still use hotpatching as part of functionality of Windows Server Datacenter: Azure Edition. This feature is included both with Windows Server 2022 Datacenter: Azure Edition and Windows Server 2025 Datacenter: Azure Edition. There are no new requirements in this case, i.e. you don’t need to Arc-enable those machines, and there’s no additional cost for it. 

How do I enable hotpatching?

First, if your server is not yet connected to Azure Arc, you can do so by following these steps. Azure Arc is available at no extra cost and lets you manage physical servers, and virtual machines hosted outside of Azure, on your corporate network, or other cloud providers. In addition to hotpatching, there are several paid Azure services you can access through Azure Arc, including Microsoft Defender for Cloud, Azure Monitor, and many others. For full details, refer to this documentation.

Once you are connected with Azure Arc, you will sign into the Azure Portal, go to Azure Update Manager, select your Azure Arc-enabled server, and select the hotpatching option as outlined in this documentation.

You can also manage your subscription to hotpatching through the Azure Portal as well.

What is the difference between hotpatches and traditional patches/LCUs? 

At Microsoft we have traditionally shipped patches known as Latest Cumulative Updates (LCU). An LCU can have a few different types of fixes in its payload such as: 

1. Security fixes 
2. Bug fixes that are not security fixes 
3. New feature payload 

In contrast, a hotpatch only includes security fixes which makes the patch smaller and scoped to security only. We still need to deliver on #2 and #3 above, so we synchronize these payloads once a quarter in the Hotpatching schedule. 

What is the hotpatching schedule?

The hotpatch service provides up to eight hotpatches in a year. It follows a three-month cycle with the first month as a baseline month (monthly cumulative update) followed by two months of hotpatches. During baseline months the machines will need a reboot. The four planned baseline months are January, April, July and October.

On rare occasions, for security reasons we may have to ship a non-hotpatch update during a hotpatch month which will also need a reboot. But the goal will be to provide up to eight hotpatches in a year. 

The Windows Server hotpatching subscription is billed monthly, so your cost will be consistent throughout the year in both hotpatch and non-hotpatch months.

Today is a big day for Windows Server! On behalf of the entire Windows Server team, I am delighted to announce Windows Server 2019 will be generally available in the second half of calendar year 2018. Starting now, you can access the preview build through our Insiders program.

What’s new in Windows Server 2019

Windows Server 2019 is built on the strong foundation of Windows Server 2016 – which continues to see great momentum in customer adoption. Windows Server 2016 is the fastest adopted version of Windows Server, ever! We’ve been busy since its launch at Ignite 2016 drawing insights from your feedback and product telemetry to make this release even better.

We also spent a lot of time with customers to understand the future challenges and where the industry is going. Four themes were consistent – Hybrid, Security, Application Platform, and Hyper-converged infrastructure. We bring numerous innovations on these four themes in Windows Server 2019.

Hybrid cloud scenarios:

We know that the move to the cloud is a journey and often, a hybrid approach, one that combines on-premises and cloud environments working together, is what makes sense to our customers. Extending Active Directory, synchronizing file servers, and backup in the cloud are just a few examples of what customers are already doing today to extend their datacenters to the public cloud. In addition, a hybrid approach also allows for apps running on-premises to take advantage of innovation in the cloud such as Artificial Intelligence and IoT. Hybrid cloud enables a future-proof, long-term approach – which is exactly why we see it playing a central role in cloud strategies for the foreseeable future.

At Ignite in September 2017, we announced the Technical Preview of Project Honolulu – our reimagined experience for management of Windows and Windows Server. Project Honolulu is a flexible, lightweight browser-based locally-deployed platform and a solution for management scenarios. One of our goals with Project Honolulu is to make it simpler and easier to connect existing deployments of Windows Server to Azure services. With Windows Server 2019 and Project Honolulu, customers will be able to easily integrate Azure services such as Azure Backup, Azure File Sync, disaster recovery, and much more so they will be able to leverage these Azure services without disrupting their applications and infrastructure.

Security continues to be a top priority for our customers. The number of cyber-security incidents continue to grow, and the impact of these incidents is escalating quickly. A Microsoft study shows that attackers take, on average, just 24-48 hours to penetrate an environment after infecting the first machine. In addition, attackers can stay in the penetrated environment – without being noticed – for up to 99 days on average, according to a report by FireEye/Mandiant. We continue on our journey to help our customers improve their security posture by working on features that bring together learnings from running global-scale datacenters for Microsoft Azure, Office 365, and several other online services.

Our approach to security is three-fold – Protect, Detect and Respond. We bring security features in all three areas in Windows Server 2019.
On the Protect front, we introduced Shielded VMs in Windows Server 2016, which was enthusiastically received by our customers. Shielded VMs protect virtual machines (VM) from compromised or malicious administrators in the fabric so only VM admins can access it on known, healthy, and attested guarded fabric. In Windows Server 2019, Shielded VMs will now support Linux VMs. We are also extending VMConnect to improve troubleshooting of Shielded VMs for Windows Server and Linux. We are adding Encrypted Networks that will let admins encrypt network segments, with a flip of a switch to protect the network layer between servers.

On the Detect and Respond front, in Windows Server 2019, we are embedding Windows Defender Advanced Threat Protection (ATP) that provides preventative protection, detects attacks and zero-day exploits among other capabilities, into the operating system. This gives customers access to deep kernel and memory sensors, improving performance and anti-tampering, and enabling response actions on server machines.

Application Platform:

A key guiding principle for us on the Windows Server team is a relentless focus on the developer experience. Two key aspects to call out for the developer community are improvements to Windows Server containers and Windows Subsystem on Linux (WSL).

Since the introduction of containers in Windows Server 2016, we have seen great momentum in its adoption. Tens of millions of container images have been downloaded from the Docker Hub. The team learned from feedback that a smaller container image size will significantly improve experience of developers and IT Pros who are modernizing their existing applications using containers. In Windows Server 2019, our goal is to reduce the Server Core base container image to a third of its current size of 5 GB. This will reduce download time of the image by 72%, further optimizing the development time and performance.

We are also continuing to improve the choices available when it comes to orchestrating Windows Server container deployments. Kubernetes support is currently in beta, and in Windows Server 2019, we are introducing significant improvements to compute, storage, and networking components of a Kubernetes cluster.

A feedback we constantly hear from developers is the complexity in navigating environments with Linux and Windows deployments. To address that, we previously extended Windows Subsystem on Linux (WSL) into insider builds for Windows Server, so that customers can run Linux containers side-by-side with Windows containers on a Windows Server. In Windows Server 2019, we are continuing on this journey to improve WSL, helping Linux users bring their scripts to Windows while using industry standards like OpenSSH, Curl & Tar.

Hyper-converged infrastructure (HCI): 

Hyper-converged infrastructure (HCI): HCI is one of the latest trends in the server industry today. According to IDC, the HCI market grew 64% in 2016 and Gartner says it will be a $5 billion market by 2019. This trend is primarily because customers understand the value of using x86 servers with high performant local disks to run their compute and storage needs at the same time. In addition, HCI gives the flexibility to easily scale such deployments.

Customers looking for HCI solutions can use Windows Server 2016 and the Windows Server Software Defined program today. We partnered with industry leading hardware vendors to provide an affordable and yet extremely robust HCI solution with validated design. In Windows Server 2019 we are building on this platform by adding scale, performance, and reliability. We are also adding the ability to manage HCI deployments in Project Honolulu, to simplify the management and day-to-day activities on HCI environments.

Frequently asked questions

Q: When will Windows Server 2019 be generally available?

A: Windows Server 2019 will be generally available in the second half of calendar year 2018.

Q: Is Windows Server 2019 a Long-Term Servicing Channel (LTSC) release?

A: Windows Server 2019 will mark the next release in our Long-Term Servicing Channel. LTSC continues to be the recommended version of Windows Server for most of the infrastructure scenarios, including workloads like Microsoft SQL Server, Microsoft SharePoint, and Windows Server Software-defined solutions.

Q: What are the installation options available for Windows Server 2019?

A: As an LTSC release Windows Server 2019 provides the Server with Desktop Experience and Server Core installation options – in contrast to the Semi-Annual Channel that provides only the Server Core installation option and Nano Server as a container image. This will ensure application compatibility for existing workloads.

Q: Will there be a Semi-Annual Channel release at the same time as Windows Server 2019?

A: Yes. The Semi-Annual Channel release scheduled to go at the same time as Windows Server 2019 will bring container innovations and will follow the regular support lifecycle for Semi-Annual Channel releases – 18 months.

Q: Does Windows Server 2019 have the same licensing model as Windows Server 2016?

A: Yes. Check more information on how to license Windows Server 2016 today in the Windows Server Pricing page. It is highly likely we will increase pricing for Windows Server Client Access Licensing (CAL). We will provide more details when available.
