Microsoft has released the cumulative update KB5094127 for Windows 10 version 22H2 as part of the June 2026 Patch Tuesday. This package is intended exclusively for devices enrolled in the Extended Security Updates (ESU) program. The cumulative update package KB5094127 (build 19045.7417) is designed for Windows 10 version 22H2 (2022 Update) on x86, x64 (amd64), and ARM64 processors.
- Search in File Explorer. Search in File Explorer has been improved, including support for Chinese text and UTF-8 encoded files without a byte order mark (BOM). Text now appears more clearly and consistently in search results, the Contents view, and tooltips.
- Dynamic Secure Boot Reporting. This update includes dynamic reporting of the Secure Boot status in the Windows Security app.
- LimitSecureBootRequiredServiceData Group Policy. A group policy and mobile device management (MDM) setting named LimitSecureBootRequiredServiceData has been added under Computer Configuration > Administrative Templates > Windows Components > Secure Boot. When enabled, Windows limits the amount of Secure Boot service data transmitted, suppressing an event that is typically sent to Microsoft. This policy is included in the Windows Restricted Traffic Limited Functionality Baseline. More details about the policy can be found in the document Manage connections from Windows 10 and Windows 11 operating system components to Microsoft services.
- Secure Boot Certificate Update. Additional high-confidence targeting data is now included in Windows quality updates, expanding the coverage of devices that automatically receive new Secure Boot certificates. Certificates are delivered only after a sufficient number of successful installation signals are received, ensuring a controlled, phased rollout.
The cumulative update KB5094127 for PCs installs automatically via Windows Update. To check for it, go to Settings > Update & Security and click Check for updates. A system restart is required to complete the installation. After the update, the Windows 10 (version 22H2) build number will change to 19045.7417.
