Microsoft has released the KB5082200 extended security update for Windows 10 to address vulnerabilities identified during the April 2026 Patch Tuesday cycle, according to BleepingComputer.
The update resolves 167 vulnerabilities, including two zero-day flaws. Users running Windows 10 Enterprise LTSC or those enrolled in the Extended Security Update (ESU) program can install the patch via the Windows Update settings menu.
One of the primary focus areas of the patch is Remote Desktop Protocol (RDP) security. The update implements new protections against phishing attacks that utilize .rdp files. When a user opens such a file, the system will now display all requested connection settings before establishing a connection, with these settings disabled by then by default.
Secure Boot and BitLocker fixes
Microsoft is also using this release to manage the transition of Secure Boot certificates. The update enables dynamic status reporting within the Windows Security App, allowing users to monitor the rollout of new certificates. This follows Microsoft's ongoing effort to replace older 2011 certificates that are set to expire in June 2026.
Additionally, the patch fixes a bug that previously caused certain Intel-based devices to enter a BitLocker recovery screen after a restart. This issue specifically affected devices supporting Connected Standby.
Beyond security, the update addresses a sign-in bug affecting Microsoft accounts. Users who installed updates on or after March 10, 2026, may have encountered "no Internet" errors when attempting to access services like Microsoft Teams, even with active connections. The KB5082200 update resolves this error.
Microsoft reports that there are no known issues associated with this latest deployment. After installation, Windows 10 systems will move to build 19045.7184, while Windows 10 Enterprise LTSC 2021 will update to build 19044.7184.
