Windows 11’s big 2026 update is almost here, and these 10 things you need to know before upgrading could save you time and frustration

Microsoft is set to launch the 2026 Update for Windows 11, known as version 26H2, later this year. This will be the fifth feature update for the operating system. The upgrade from version 25H2 to 26H2 will utilize an Enablement Package (eKB), allowing for a transition similar to a standard monthly cumulative update without requiring a full reinstallation. Users can also upgrade from Windows 10 using an ISO file or Microsoft installation media, which ensures files, applications, and settings remain intact. Upgrading to version 26H2 extends the support lifecycle of devices by an additional year, with Microsoft providing 24 months of support for Home and Pro editions and 36 months for Enterprise and Education editions. Version 25H2 will continue to receive support until October 2027, and users are advised to plan upgrades before this support ends. Windows 11 version 26H2 has the same hardware requirements as version 25H2, which include a 1GHz processor with at least two cores, 4GB of RAM, 64GB of storage, UEFI firmware with Secure Boot, TPM version 2.0, DirectX 12 compatible graphics, and a high-definition display. The rollout of the update will be gradual, following a Controlled Feature Rollout (CFR) strategy, meaning not all devices will receive the update immediately.

Windows Netlogon Flaw CVE-2026-41089: CVSS 9.8 [2026]

CVE-2026-41089 is a critical vulnerability in the Windows Netlogon service, rated 9.8 on the CVSS scale, allowing unauthenticated attackers to execute arbitrary code with SYSTEM-level privileges on domain controllers. It affects all supported versions of Windows Server configured as domain controllers, from Windows Server 2012 R2 to the latest release. Microsoft addressed this vulnerability on May 12, 2026, during a broader update that included 138 fixes, but it went largely unnoticed until early June when active exploitation was confirmed. The vulnerability is characterized as a stack-based buffer overflow and is considered "wormable" due to its ability to self-propagate across systems without user intervention. Organizations are advised to patch all domain controllers and audit network access to mitigate exposure.

This unofficial PowerShell script for improving Windows 11 gets a useful driver feature

This weekend, discussions emerged reflecting user frustration with Windows 11 and Microsoft products, particularly regarding updates. A recent cumulative update introduced a customizable Start menu but also fixed a bug that was consuming users' storage. Microsoft has mandated that users cannot ignore these updates, contributing to dissatisfaction.

Microsoft explains the different types of Windows updates you get

Microsoft provides various types of Windows updates, including Patch Tuesday updates, which occur on the second Tuesday of each month. An example is the KB5094126 update for Windows 11, released on June 9, which includes both security and non-security content. IT administrators can use tools like Autopatch, Intune, and WSUS to deploy these updates. Hotpatching allows security updates to be applied without restarting devices. Optional non-security preview updates are released in the fourth week of each month for testing purposes and can be accessed by users on non-IT-managed devices. Out-of-band (OOB) updates can be issued at any time to address significant issues or vulnerabilities. Microsoft also enhances Windows 11 through annual updates, monthly updates, and Microsoft Store offerings, utilizing Controlled Feature Rollout (CFR) for feature deployment. Users are encouraged to keep their systems updated and can join the Windows Insider Program for early access to new features.

Microsoft Confirms Windows 11 Bug That Can Consume Over 500GB of Storage Through Permission Log File

Microsoft has acknowledged a bug in Windows 11 that causes the Capability Access Manager's write-ahead log file to expand indefinitely, potentially exceeding 500GB of storage on affected devices. This issue is addressed in update KB5095093, which includes builds 26200.8737 and 26100.8737. Users can manually install this update via the optional updates section of Windows Update or wait for its automatic rollout during the July 2026 Patch Tuesday. The Capability Access Manager manages app permissions and logs usage of privacy-sensitive features, but the WAL file continues to grow unchecked on affected systems. The file can reach sizes from 70GB to over 513GB. To check if a system is affected, users can check storage settings or use Robocopy to verify the file size. The update is available through the Optional updates section and will be included in the cumulative update on July 8, 2026. The excessive size of the WAL file can lead to critical storage shortages and related issues, but it does not compromise the security or core functionality of the permission system. Microsoft has not confirmed if Windows 11 26H1 Insider builds are affected.

Microsoft to enable Windows settings backup by default for orgs

Microsoft will enable the Windows settings backup and restore tool by default for enterprise systems joined to Microsoft Entra or operating in a hybrid environment with the upgrade to Windows 11 version 26H2. This tool, previously known as Windows Backup for Organizations, assists users in backing up and restoring Windows settings after events like device resets or upgrades. The tool debuted at the Microsoft Ignite conference in November 2024, became publicly available in August 2025, and requires the September 2025 Windows Monthly Cumulative Update for access. The default-on setting applies only to eligible devices where administrators have not set the policy otherwise, and IT administrators can manage this through mobile device management solutions. Restore functionality will not be enabled by default and requires administrative configuration. The default-on behavior will also be available in the Windows Insider Program Experimental channel starting July 2026.

Microsoft released Windows 11 KB5095189 OOBE (initial OS setup) update for 25H2, 24H2

Microsoft released a preview update designated as C-release under KB5095093, along with dynamic updates KB5102558 and KB5095615, focusing on setup and recovery enhancements for Windows 11. A new Out of Box Experience (OOBE) update has been introduced for Windows 11 versions 25H2 and 24H2. The OOBE is the initial setup phase after Windows installation. The cumulative update KB5095189, dated June 23, 2026, enhances the OOBE process for these versions. OOBE updates are installed automatically for users with an active internet connection. During OOBE, Windows automatically downloads and installs critical driver updates and zero-day patches once connected to a network. If a newer version of Windows is available, it may also be downloaded and installed during the OOBE process, ensuring the device has the latest security measures and features upon completion of the setup.
