Windows 11 release information toolbox from Microsoft

Keeping up with Windows doesn't mean constantly checking a single website. This guide maps the Windows release information resources available to you in 2026, so you can find the right information at the right time, whether you're checking what's new, investigating an issue, planning an update, or simply trying to stay informed. We'll talk about each resource individually below, but here's a quick decision guide you can reference.

Start with Windows release health​

Windows release health is a good place to start when you need authoritative information about the status of a Windows release. Here you can find the rollout status of each release, known and resolved issues, safeguard holds, servicing milestones, and other information that can help you manage your Windows device estate.

Use Windows release health when you need to answer questions such as:

• What are the latest Windows updates and servicing milestones?
• What is the current status of a Windows feature update rollout?
• Where can I find information about a specific version of Windows?
• Is there a known issue affecting this Windows version?
• Has an issue been resolved?
• Is a safeguard hold preventing certain devices from receiving a feature update?

Tip: Bookmark Windows release health so it's easy to find when you need to investigate an issue or check the status of a release.

Understanding each Windows release​

Sometimes you don't need to troubleshoot an issue. You simply need to know which Windows releases are currently supported, which build you're running, or when a version is going to reach the end of updates or end of support. Windows release information pages can help you understand the servicing status and update history for supported versions of Windows.

For information about an individual monthly update, turn to Windows release notes. Release notes provide details about a specific update, so you can understand what's included and review information relevant to that release.

Each in-market version of Windows client and Windows Server has its own update history page with a convenient list of all release notes published to date. For example:


If your organization uses hotpatch updates, there are two additional resources you should know about.

• You'll find the Windows 11 hotpatch calendar on the Windows 11 release information page, providing a dedicated place to check the hotpatch release schedule.
• Then you can reference the dedicated hotpatch release notes for information about hotpatch updates.

Together, these resources help you know when hotpatch updates are scheduled and where to find details about the releases themselves.

Both release information pages and release notes help you understand "Which version or build am I looking at?" and "What changed in this particular update?"

Checking for known issues​

When something isn't working as expected, Windows release health provides information about known issues that might have a broader impact on devices, functionality, or deployments across supported versions of Windows client and Windows Server.

Known issue information can help you determine whether Microsoft is already investigating an issue, whether a resolution or workaround is available, and whether an issue has been resolved. You can also find information about safeguard holds that might affect the availability of a feature update for some devices.

Consider checking known issues both when you're investigating unexpected behavior and as part of your planning for a Windows feature or monthly update.

Tip: Windows release health is also integrated into the Microsoft 365 admin center, making it easier for IT admins to manage Windows alongside Microsoft 365 products and services. You can proactively view information or sign up for email notifications to have information delivered straight to your inbox.

Keep up with timely announcements​

Not every Windows announcement or advisory warrants a long-form article. That's where the Windows message center comes in.

The public Windows message center provides concise announcements about Windows servicing, lifecycle milestones, known issues, upcoming changes, events, and other information that might require your awareness.

Think of it as a way to quickly answer:

Is there anything happening with Windows that I should know about right now?
For IT admins that have access to the Microsoft 365 admin center, you can find Windows announcements alongside updates on other Microsoft 365 products in the Microsoft 365 message center there. Windows items in the Microsoft 365 message center often contain more technical details on rollout schedules, impact, recommendations, and compliance considerations.

Want to opt in to receive a weekly digest that includes Windows-related updates posted to the Microsoft 365 message center?

1. In the Message center, select Preferences.
2. On the Custom View tab, select the services you want to monitor, including Windows.
3. On the Email tab, select or add the email address that will receive the notifications.
4. Select the box for Send me a weekly digest about services I select and select Windows.

You can also choose to receive same-day email messages for major updates. This is especially useful if you manage Windows across an organization and need to keep track of changes that could affect deployment or support.

Note: You can enter up to two additional email addresses to receive Microsoft 365 message center notifications. Message center weekly digests emails are currently sent in English only.

Go deeper with the Windows IT Pro Blog and Microsoft Learn​

Announcements tell you what's happening. Sometimes you need to understand why it matters, what to do next, and where to find guidance you can return to over time.

That's where the Windows IT Pro Blog and Windows documentation on Microsoft Learn work together. Look to the Windows IT Pro Blog when you need context around a change, including why it matters, how to plan or prepare, and what your IT team should consider as you manage Windows in your organizations.

For authoritative technical guidance, turn to Microsoft Learn. Technical documentation on Learn reflects the comprehensive product description, prerequisites, and guidance you should use to deploy, configure, manage, and troubleshoot Windows. It's updated as that information evolves. While a blog post captures information and recommendations at the time of publication, the corresponding technical documentation should be your ongoing reference.

Watch and learn​

Prefer to see what's changed rather than read about it? Each month, you can watch a short Windows 11 release notes companion video. Get a quick overview of what's in that month's update and a short tip to help you get the most from your Windows experience. For IT admins, Ctrl + Manage offers a closer look at what's changed, why it matters, where it fits, and what you should do next when it comes to the latest and upcoming capabilities in Windows management.

Ask the experts​

Sometimes documentation isn't enough because your question depends on your organization's environment, deployment strategy, or management scenario. Community events add an important dimension to your Windows information toolbox: the opportunity to engage directly with the experts.

Community events like Windows Office Hours, Tech Community Live, Technical Takeoff, and Ask Microsoft Anything (AMA) turn Windows communications into a two-way conversation. They give you opportunities not only to learn, but to ask questions, share your scenarios, and get answers. It's your chance to interact with the engineering and product teams building and supporting Windows, Windows 365, Microsoft Intune, and security capabilities.

Sign in to the Tech Community and follow the Windows events page to be notified when new events are announced.

Put your Windows information toolbox to work​

With the right resources at your fingertips, you can stay ahead of changes, make informed decisions, and better prepare your organization for what's next. The key is knowing where to look and choosing the resources that best fit how you work.
