Hello Microsoft Support Team,

I would like to confirm the official End of Life (EOL) and End of Support date for Windows 11 Enterprise, version 23H2.

According to the Windows lifecycle information, Windows 11 Enterprise 23H2 support is scheduled to end on May 11, 2027.

Could you please confirm:

  1. Is May 11, 2027, the final date for security updates and monthly cumulative updates?
  2. Will Windows 11 Enterprise 23H2 receive security updates until this date?
  3. After May 11, 2027, will devices stop receiving regular security updates?
  4. Is upgrading to Windows 11 Enterprise 24H2 or a later supported version required before this deadline?

Please share the official Microsoft documentation confirming the lifecycle details.

Thank you.

    Welcome to Microsoft Q&A!

    Thank you for reaching out and for taking the time to verify the lifecycle information before planning your Windows upgrade.

    Based on Microsoft’s currently published lifecycle documentation, Windows 11 Enterprise, version 23H2 reaches end of updates on November 10, 2026, not May 11, 2027.

    Microsoft’s Windows 11 release information lists November 10, 2026 as the end-of-updates date for Windows 11 version 23H2 Enterprise and Education editions. Microsoft’s Windows release health page for version 23H2 also states that Enterprise and Education editions will reach end of updates on this date and, afterward, will no longer receive monthly security updates containing protections from the latest security threats.

    Therefore, based on the information currently published by Microsoft:

    • Windows 11 Enterprise 23H2 remains serviced until November 10, 2026.
    • It will continue receiving applicable monthly security and cumulative quality updates while the version remains in support.
    • After the end-of-updates date, devices can continue to run Windows 11 Enterprise 23H2, but the release will no longer receive its regular monthly security updates.
    • To continue receiving regular monthly security updates, affected devices should be moved to a supported Windows 11 version before Windows 11 Enterprise 23H2 reaches end of servicing.

    The May 11, 2027 date may have come from an older or different lifecycle reference. Windows lifecycle dates can vary depending on the Windows version and edition, so I would recommend using the current Microsoft lifecycle and Windows release-health pages as the authoritative references rather than planning around the May 2027 date.

    I recommend planning the upgrade of the affected Windows 11 Enterprise 23H2 devices to a currently supported Windows 11 release before November 10, 2026.

    Before deploying the feature update broadly, validate the target Windows version against your organization’s applications, drivers, security products, and device-management policies.

    As a next validation step, you can run winver on a representative device and confirm that it is running Windows 11 Enterprise, version 23H2.

    You can then review your Windows Update for Business, Microsoft Intune, Configuration Manager, or WSUS deployment policy to make sure those devices have an upgrade path to a supported Windows release before the end-of-updates date.

    Moreover, I want to clarify with you about the limitation of what we can confirm through Microsoft Q&A.

    Microsoft Q&A is a community-based technical support forum. From here, I can help interpret and point you to Microsoft’s currently published official lifecycle documentation, but I cannot provide a separate official or contractual confirmation on Microsoft’s behalf, guarantee that a lifecycle date will never change, or confirm an exception or extended servicing arrangement that is not documented in Microsoft’s public lifecycle information.

    In other words, I can confirm that the currently published Microsoft documentation identifies November 10, 2026 as the end-of-updates date for Windows 11 Enterprise 23H2. However, if by “official confirmation” you require a formal statement from Microsoft Support for contractual, compliance, audit, or organization-specific purposes, that is beyond what can be provided through the Microsoft Q&A forum.

    For lifecycle and deployment planning, please refer to these official Microsoft sources:

    These Microsoft pages should be treated as the authoritative sources for the currently published lifecycle dates.

    I hope this helps clarify both the Windows 11 Enterprise 23H2 lifecycle and what can be confirmed through the Microsoft Q&A forum.

    May 11, 2027 is not the currently published end-of-support date for Windows 11 Enterprise, version 23H2; Microsoft lists November 10, 2026 as its end-of-updates date. ^1^

    Confirmed lifecycle details

    • Final security update: The November 2026 Windows security update is the last update for Windows 11 Enterprise 23H2. ^2^
    • Updates until then: Enterprise 23H2 continues receiving monthly cumulative security updates through its servicing period. Windows monthly security releases are cumulative, so each includes preceding updates. ^1^
    • After November 10, 2026: Devices remain operational, but they no longer receive regular monthly security updates containing protection against newly addressed threats. ^3^
    • Microsoft also states that fixes for known issues, time-zone updates, technical support, and monthly preview updates end for this version. ^4^

    The lifecycle page displays the retirement boundary as November 11, 2026 at 6:59:59 AM Pacific Time, while release-health documentation describes November 10, 2026 as the end-of-updates date. These represent the published lifecycle boundary and the servicing/update date respectively; use November 10, 2026 as the operational deadline for deployment planning. ^5^

    Upgrade requirement

    Upgrade devices to a Windows 11 release that remains supported before the November 10, 2026 deadline if they must continue receiving monthly security and quality updates.

    As of the published lifecycle table:

    Enterprise release End of updates
    23H2 November 10, 2026
    24H2 October 12, 2027
    25H2 October 10, 2028
    26H2 October 9, 2029

    These dates are listed on Microsoft’s Windows 11 release-information page. ^1^

    Although 24H2 is still supported, it provides a shorter remaining servicing window than 25H2 or 26H2. Select the newest supported release that is compatible with your devices and approved by your organization rather than upgrading only to 24H2.

    For an eligible device, check availability under:

    1. Settings → Windows Update
    2. Select Check for updates.
    3. If a supported feature update is offered, select Download and install. ^3^

    For managed Enterprise devices, schedule deployment through the organization’s normal Windows update-management platform and allow time for application, driver, security-baseline, and rollback testing before the deadline.
