Windows 10 KB5094127 Patch Tuesday improves File Explorer search and more

This month's security update for Windows 10 enhances search in File Explorer, brings Secure Boot updates and more.

The June 2026 Patch Tuesday updates are here, bringing mandatory patches to users with PCs enrolled in the Extended Security Update program for Windows 10. Microsoft is rolling out KB5094127, with build numbers 19045.7417 and 19044.7417. Changelog includes the following:

[File Explorer] This update improves File Explorer search, including support for Chinese text, and UTF 8–encoded files without a byte order mark (BOM). Text now displays more clearly and consistently across search results, Content view, and tooltips.

[Secure Boot]

This update enables dynamic status reporting for Secure Boot states in Windows Security App.
This update adds a new policy setting, LimitSecureBootRequiredServiceData, under Computer Configuration > Administrative Templates > Windows Components > Secure Boot. When this setting is enabled, Windows limits the Secure Boot service data it sends by suppressing the event normally sent to Microsoft. This policy is also included in the Windows Restricted Traffic Limited Functionality Baseline package. For information about the policy, see Manage connections from Windows 10 and Windows 11 operating system components to Microsoft services.
With this update, Windows quality updates include additional high confidence device targeting data, increasing coverage of devices eligible to automatically receive new Secure Boot certificates. Devices receive the new certificates only after demonstrating sufficient successful update signals, maintaining a controlled and phased rollout.

As for known bugs, Microsoft has the following to say:

Some devices with an unrecommended BitLocker Group Policy configuration might be required to enter their BitLocker recovery key on the first restart after installing this update.

This issue only affects a limited number of systems in which ALL the following conditions are true. These conditions are unlikely to be found on personal devices not managed by IT departments.

A workaround is available in the official documentation.

Today's updates are available for PCs enrolled in the Extended Security Updates program only. If your PC is eligible, you can download the update from Settings > Windows Update or from the Microsoft Update Catalog here.
