Starting in May 2026, Windows update management is changing significantly. Microsoft is enabling hotpatch updates by default for all eligible devices managed through Windows Autopatch. This makes reboot-free security patching not just an option, but the new standard. For organizations, this represents a fundamental shift in how they approach patching, compliance, and continuity.
This blog walks you through the key developments: hotpatching as the default, the impact on security and compliance, the new management controls for admins and the role of Autopatch in modern update management.
Hotpatching becomes the default starting May 2026
Microsoft has announced that hotpatch updates will be automatically enabled starting with the May 2026 Windows security update for all eligible devices managed through Intune or the Graph API. This means security updates will be applied without a restart, making them effective immediately.
Where hotpatching was previously an opt-in feature, it now becomes the default. This fits into Microsoft’s broader strategy to roll out security updates faster, more consistently, and with less disruption.
Note: Hotpatching only works on devices that meet specific prerequisites, which can be found here. Devices that do not meet these requirements will continue to be patched in the traditional way.
An important practical detail: devices must first install the April 2026 security update as a baseline — which still requires a restart. Only after that will they receive hotpatch updates from May 2026 onwards without restarts.
Fewer reboots, faster security
The biggest benefit of hotpatching is clear: security updates are applied without users needing to restart their device. This has a direct impact on the speed of patch compliance.
Microsoft backs this up with data from four companies with 30,000 to 70,000 devices: all of them achieved 90% patch compliance in half the usual time, without making any policy changes. Today, more than 10 million production devices are running hotpatch updates, underscoring the level of trust companies have placed in this technology.
This is possible because:
- updates are active immediately, without depending on user behavior
- the traditional “3–5 day reboot window” is eliminated
- vulnerabilities are patched faster, reducing the risk of zero-day exploits
For organizations struggling with lagging updates, hybrid workplaces, or critical systems that cannot simply be restarted, this is a huge step forward.
New management controls from April 1, 2026
While hotpatching is becoming the default, control remains important. Microsoft is therefore introducing new management controls starting April 1, 2026. These allow you as an admin to decide whether and how quickly your organization transitions to hotpatching.
Since April is a hotpatch baseline month, you effectively have until May 11, 2026 before the first hotpatch updates are deployed. That gives you six weeks to act.
Opt out at the tenant level
Want to disable hotpatching for the entire tenant? You can do so via:
Intune > Tenant administration > Windows Autopatch > Tenant management > Tenant settings
Toggle the “When available, apply updates without restarting the device (hotpatch)” setting to Block.
Opt out for groups of devices
You can also exclude specific groups of devices via a Quality Update Policy. Windows Autopatch respects the policy-level setting over the tenant-level default. This is useful for:
- organizations with complex application landscapes
- environments with strict change management procedures
- situations where additional validation is required
- temporary exceptions or phased adoption
You can also take the reverse approach: disable hotpatching tenant-wide and only enable it for specific groups that are ready.
The message is clear: hotpatching becomes the norm, but organizations retain the ability to set their own pace.
Autopatch as the foundation of modern update management
Hotpatching is not a standalone feature. It fits into a broader movement in which Microsoft positions Windows Autopatch as the modern way to manage updates intelligently, predictably, and automatically.
Autopatch offers:
- ring-based deployments that minimize risk
- automatic rollback in case of issues
- insight into update status and compliance
- integration with Intune and Microsoft 365
- an increasingly autonomous update ecosystem
With hotpatching as the default, Autopatch becomes even more attractive for organizations looking to modernize and automate their update management. The service is shifting from “convenient automation” to “strategic necessity.”
What does this mean for your organization?
The transition to hotpatching as the default has impact on multiple levels:
- Security — faster protection, fewer open vulnerabilities
- Compliance — higher and faster patch percentages
- Continuity — fewer disruptions, fewer reboots, higher uptime
- Management overhead — fewer manual actions, more focus on exceptions
- Governance — new controls require a review of policies and processes
The concrete action for admins: check now whether your devices meet the hotpatch prerequisites using the Hotpatch quality updates report in Intune. That way you won’t be caught off guard in May.
For many organizations, this is the moment to revisit their update strategy — not just technically, but organizationally as well.
Conclusion
With hotpatching as the default, Microsoft is taking a major step toward a future where security updates are applied immediately, silently, and without disruption. The combination of faster compliance, fewer reboots, and new management controls makes this one of the most significant changes in Windows update management in recent years.
Autopatch plays a central role in this: it is increasingly becoming the foundation of modern, autonomous, and intelligent update management.
The exact impact of this change depends on your environment, processes, and application landscape. What is certain: April 1, 2026 is the date to act — that’s when the opt-out goes live, and you have until May 11 to determine your position.
