What’s New in Windows 10 Build 19045.7291?

The latest build introduces some notable improvements, particularly in File Explorer:

• Search bar performance has been enhanced, making it faster and more responsive, even with non-English system languages.
• Text in search results, content view, and tooltips now displays more clearly and consistently.

Additionally, Microsoft is expanding the rollout of the Secure Boot update to more devices. To verify the status of Secure Boot on your PC, follow these steps:

1. Open the Windows Security app.
2. Navigate to Device Security.
3. Locate the Secure Boot section and check the status.

The Secure Boot status will display one of the following:

• Green: Certificates are fully updated.
• Yellow: Secure Boot is not updated and requires attention.
• Red: Device will no longer update the boot loader.

If updates are required, you may need to contact your OEM for an updated UEFI/BIOS. Microsoft has also introduced a new group policy, LimitSecureBootRequiredServiceData, giving enterprises more control over Secure Boot certificates.

Known Issues with KB5094127

Microsoft has not reported any new issues with this update. However, an existing issue may cause some users to encounter the BitLocker recovery screen, which requires entering a recovery key to proceed. This issue only affects devices with a specific Group Policy enabled, which is not turned on by default.

For most users, the update applies smoothly, as Windows 10 is now in its extended support phase, with Microsoft focusing more on Windows 11 development.

Windows 10 Support is Ending Soon

Microsoft ended mainstream support for Windows 10 in October 2025. However, the Extended Security Updates (ESU) program has been made available at no extra cost to consumers, while enterprises are charged for continued support. This program will end on October 13, 2026, less than four months from now.

After this date, further extensions will only be available to enterprises willing to pay for additional licensing. To ensure continued support and security, users are advised to upgrade to Windows 11 as soon as possible.
