Microsoft is set to release Windows 11 version 26H2, an enablement package based on version 25H2, without introducing new features at launch. The update will require only a single restart for devices on versions 25H2 or 24H2, while users on older versions, such as 23H2 or Windows 10, will need a full feature update. Both versions share identical features and are built on the same platform, with version 26H2 using build numbers in the 26300 series. The update process will vary depending on the current version, and version 26H2 will not change hardware requirements. Microsoft plans a gradual rollout of the update, initially as an optional install. Version 26H2 aims to extend support, adding approximately a year to the support timeline, with version 25H2 support continuing until October 2027. Users should verify their current version and back up important files before upgrading.

Secure Boot certificates are automatically updated through Windows updates, ensuring boot security across various hardware. KB5101650 installs primarily through the Windows Update interface, requiring a restart to activate changes. Enterprise environments can use the Microsoft Update Catalog for manual distribution. A temporary restriction affects certain Dell devices with Intel Innovation Platform Framework drivers, which Microsoft plans to address in a future update. The cumulative update resolves a total of 622 Microsoft CVEs, including 416 affecting Windows components. Users are advised to verify and install the update promptly to secure the full suite of improvements.

Microsoft has released a guide on the Windows servicing model, detailing monthly security updates, optional preview releases, hotpatch updates, and feature rollout mechanisms. Patch Tuesday occurs every second Tuesday of the month, delivering cumulative security updates to supported Windows versions. For consumers and small businesses, updates are managed through Windows Update, while enterprises can use various tools like Windows Autopatch and WSUS. Hotpatch updates, which focus on security fixes, can be installed without a restart, unlike quarterly baseline updates that require one. Optional non-security preview updates are released in the fourth week of each month for testing upcoming fixes and new features, available only for the latest supported Windows versions. Unmanaged devices can access these updates through Windows Update settings, while IT-managed devices depend on organizational policies. Microsoft also issues out-of-band updates to address urgent issues, which can be deployed through enterprise management tools. New features for Windows 11 are rolled out throughout the year via various channels, with a gradual rollout strategy to monitor quality and compatibility, using the Controlled Feature Rollout approach.

Microsoft has extended the availability of Windows Server 2022 hotpatching until 2027, specifically for the Windows Server 2022 Datacenter: Azure Edition. Mainstream support for Windows Server 2022 will end on October 13, 2026, while extended support will last until October 14, 2031. Hotpatching allows administrators to apply security updates without server downtime, although quarterly cumulative updates requiring a reboot will still occur. This feature is exclusive to Azure Edition users, with no similar support for on-premises users of Windows Server 2022. Additionally, hotpatch updates are being introduced for Windows 11 24H2 Enterprise clients and are now the default for Windows Autopatch.

Microsoft has confirmed the upcoming Windows 11 26H2 feature update, set to roll out in fall 2026, likely in October. This update will not be a major overhaul and will utilize an enablement package (eKB) for installation, similar to the previous Windows 11 25H2 version. The last major update was the 24H2 version, released on October 1, 2024, while 25H2 launched in 2025 and reset the OS life cycle, extending support by an additional year. Support for Windows 11 24H2 ends on October 13, 2026, and for 25H2 until October 12, 2027. Windows 11 26H2 will be supported until October 2028 for Home, Pro, Pro EDU, and Pro for Workstations editions, and until October 2029 for Enterprise, Education, or IoT Enterprise editions. Devices running Windows 11 24H2 or 25H2 will transition to 26H2 without new hardware requirements, maintaining specifications of 4GB RAM, 64GB storage, and a 1GHz or faster 64-bit dual-core processor. Windows 11 26H1, another update, requires new silicon but does not introduce exclusive features. Major changes will be delivered through monthly cumulative updates rather than annual feature updates.

Microsoft resolved an issue affecting the installation of Windows updates released since May 2025, which primarily impacted users using the Windows Update Standalone Installer (WUSA) from a network share, especially in enterprise environments. The problem was significant for devices running Windows 11 24H2/25H2 and Windows Server 2025, but did not occur when handling a single .msu file or when files were stored locally. In August 2025, Microsoft acknowledged that updates installed using WUSA might fail with error ERRORBADPATHNAME when multiple .msu files were involved. A Known Issue Rollback Group Policy was implemented in September 2025 to mitigate the impact on home and non-managed business devices. The issue was ultimately resolved with cumulative updates released in June 2026 for Windows 11 (KB5079391) and Windows Server 2025 (KB5094125). Microsoft provided a workaround for users experiencing difficulties with prior updates by suggesting they save .msu files locally for installation. Users were also advised to wait at least 15 minutes after installing an .msu file via WUSA before checking the Update History page. Additionally, Microsoft had previously addressed another issue in April 2025 that affected enterprise customers installing security updates via WSUS, which recurred in the August 2025 updates. Microsoft warned customers about potential issues with installing the latest monthly updates on devices upgraded to Windows 11 24H2 or 25H2.

Microsoft has resolved an issue affecting certain Windows Server 2025 devices that were booting into BitLocker recovery mode after the April 2026 security update. This issue was linked to specific BitLocker Group Policy configurations and required users to input their BitLocker recovery key upon the first restart after the update. However, this key would only need to be entered once for subsequent restarts, provided the group policy configuration remained unchanged. The problem primarily affected enterprise systems rather than personal devices. The issue arose under specific conditions: BitLocker was enabled on the operating system drive, a particular Group Policy was set, the Secure Boot State PCR7 Binding was "Not Possible," the Windows UEFI CA 2023 certificate was present, and the device was not already using the 2023-signed Windows Boot Manager. Microsoft released fixes in the KB5094125 and KB5093998 updates to address this problem, preventing devices with incompatible group policy configurations from installing the 2023-signed Windows Boot Manager. Event ID 1032 in the System event log indicates the issue when Windows updates are installed. For IT administrators unable to deploy the latest updates, it is recommended to remove the Group Policy configuration before installing updates or to implement a Known Issue Rollback (KIR) on affected devices. Additionally, Microsoft had previously addressed similar BitLocker recovery issues in August 2024 and May 2025.
