When does Windows 11 support end? Dates and complete guide

If you have any questions about when support for Windows 11 ends , here you'll find everything you need, gathered and explained: official dates by version and edition, how Microsoft's lifecycle policy works, and what to do to stay up-to-date without any surprises.

It's important to distinguish between an operating system being live and a specific version reaching its end of support . Windows 11 as a platform is still supported, but some versions (21H2, 22H2, 23H2, 24H2…) have an expiration date, especially the Home and Pro editions, which have less service life than the Enterprise and Education editions.

Lifecycle Policy: What “End of Support” Really Means

Microsoft manages Windows 11 under the Modern Lifecycle Policy . This involves annual releases with limited support per version and the requirement to upgrade regularly to continue receiving security and quality updates.

When a version reaches its "end of support," the system continues to boot, but security patches , fixes, and non-security-related changes are no longer released. From that point on, each passing month increases the risk: greater exposure to vulnerabilities, incompatibilities with new apps , and potential problems with recent hardware .

Microsoft's website lists, month by month, the products that are being retired or reaching the end of support. In 2025, for example, this includes not only Windows editions, but also components such as Configuration Manager , Dynamics 365 Business Central, and the annual channel version of Windows Server 23H2.

Windows 11 Home and Pro: Affected Editions and Scope

The editions affected by these dates are Home, Pro, Pro Education, Pro for Workstations, and SE . All of them are governed by the modern Directive, with a shorter lifecycle than the enterprise editions.

According to official data, Windows 11 Home/Pro entered full support as a product on October 4, 2021 , and remains under technical support at the platform level. What changes are the support periods for each specific version.

Key dates by version of Windows 11 (Home/Pro)

Microsoft documents the lifecycle of each Home/Pro version on its lifecycle page. These are the most relevant milestones for home and non-enterprise professional users, with the most important end-of-support dates :

• Windows 11 21H2: start 04/10/2021, end 10/10/2023. This first version is no longer patched.
• Windows 11 22H2: Start date: 20/09/2022, end date: 08/10/2024 for Home/Pro. 22H2 Enterprise/Education editions have a different schedule (see below).
• Windows 11 23H2: Start date: 31/10/2023, end date: 11/11/2025 for Home/Pro. If you're in 23H2 and a home or professional user, this is the date to watch.
• Windows 11 24H2: start 01/10/2024, end 13/10/2026 for Home/Pro, according to information gathered from the cited sources.

Beware of notifications in Windows Update : a recent update generated erroneous end-of-support notices for 23H2 . Below we explain the issue and what to do if you see it.

Key release dates for Enterprise, Education, and IoT Enterprise

If you use enterprise editions, support is longer. Published and cited references indicate an additional year of support compared to Home/Pro for each version, with these dates noted:

• Windows 11 22H2 (Enterprise, Education, IoT Enterprise): End of support on 14/10/2025.
• Windows 11 23H2 (Enterprise, Education, IoT Enterprise): end 10/11/2026.
• Windows 11 24H2 (Enterprise, Education, IoT Enterprise): end 12/10/2027.

This confirms that, although Windows 11 does not have a "death date" as a platform, each version does expire and will force you to upgrade to stay supported.

Context: Windows 10 end of support

For reference, Microsoft has set October 14, 2025, as the end of support for Windows 10 22H2 , its latest version. Security updates and technical support will cease on that day. If you want to know what happens if you stay on Windows 10 , consult the related guide.

Intermediate versions have been phased out before: for example, Windows 10 21H2 stopped receiving updates on June 11, 2024. If you still depend on Windows 10, it's time to plan your upgrade to Windows 11 or the latest available version.

Patch History: B, D, and OOB Update Pace

Windows 11 receives monthly "B" patches (the traditional Patch Tuesday), optional "D" patches at the end of the month, and out-of-band (OOB) patches when urgent. The published history for the 22621.x branch (the technical basis for 22H2/23H2) shows an uninterrupted release schedule from 2022 to 2025.

This list includes, for example, KB5046633 (B, 11/12/2024) , KB5044285 (B, 10/08/2024), KB5044380 (D, 10/22/2024), and KB5055528 (B, 04/08/2025), along with out-of-body cumulative updates such as KB5019509 (10/18/2022) and KB5058919 (04/11/2025). The builds range from 22621.674 in 2022 to 22621.5909 (09/09/2025).

This pattern makes it clear that as long as your version remains within its support window, you'll receive security and quality patches at a predictable pace. When support ends, that tap shuts off completely.

End of support notice for 23H2 bug (KB5046633)

Some users recently saw a notification in Windows Update indicating that Windows 11 23H2 was nearing its end of support . This is attributed to update KB5046633, which generated confusing messages even on updated systems.

Microsoft acknowledged the issue as a reporting error and stated they were working on a fix from the cloud. As a temporary solution, some users found that logging out and restarting their PCs worked; otherwise, they had to wait for the official fix.

If you receive a similar notification and you're on version 23H2 within the support period, check Windows Update after a restart. If the problem persists, don't worry: it's a false positive that was already identified and awaiting correction when it occurred.

What it means to be without support and why it should be avoided

Continuing to use an unsupported version exposes you to threats such as ransomware, spyware, and unpatched exploits. Furthermore, newer apps eventually become incompatible, and you may experience bugs and performance issues.

Even if your PC is still working, the lack of security patches makes the system an easier target. In professional environments, it can also impact regulatory compliance and increase operational risk.

How to stay in support: upgrade to a current version

The most direct way to stay protected is to update to the latest version of Windows 11 that is still within its support window . You can do this from Settings or using the Windows 11 Setup Wizard, and it's a good idea to verify compatibility using the "PC Health Check" tool.

For unsupported devices , the cited sources included the method documented by Microsoft to allow the update on devices without supported CPU/TPM, through a change in the Registry. If you need this method, this is the command indicated in those references:

reg add HKLM\SYSTEM\Setup\MoSetup /f /v AllowUpgradesWithUnsupportedTPMorCPU /d 1 /t reg_dword

Keep in mind that while this setting is documented in Microsoft's documentation, enabling it may result in support limitations and additional risks. If your computer is relatively new, check your UEFI/BIOS to see if TPM 2.0 is present but disabled.

Where to check your product's life cycle

Microsoft maintains official pages where you can check the lifecycle of your product and version. There you can see if your edition is still supported and when it will receive further patches.

For Windows 11 Home and Pro, the reference is Microsoft's lifecycle page: Windows 11 Home and Pro – Lifecycle . For the end of support for Windows 10, see Microsoft – End of support for Windows.

Official List 2025: Products Retiring or Ending Support

In 2025, Microsoft's list includes retirements and end-of-support products from both the modern and fixed policy eras . These include Dynamics 365 Business Central (various releases), Configuration Manager (2309, 2403), the Windows Server 23H2 annual channel, and specific editions/branches of Windows 11.

The dates that affect Windows 11 are especially relevant: Enterprise/Education 22H2 and IoT Enterprise 22H2 end on 10/14/2025; Home/Pro 23H2 ends on 11/11/2025. These are the "signals" to watch throughout the year.
