KB5082200

Microsoft released cumulative update KB5082200 for Windows 10, version 22H2 as part of the April 2026 Patch Tuesday for devices enrolled in the Extended Security Updates (ESU) program. The cumulative update package KB5026435 (Build 19045.7184) is intended for Windows 10 version 22H2 (2022 Update) on x86, x64 (amd64), and ARM64 processors. Support for Windows 10 has ended: as of October 14, 2025, the system only receives updates under the Extended Security Updates (ESU) program.

• Security improvements for internal OS functions. The update includes various security improvements for internal OS functions from April 2026. Patch Tuesday, April 2026: Microsoft fixed 167 security issues, including two zero-day vulnerabilities.
• Protection against phishing via RDP. Enhanced protection against phishing attacks using Remote Desktop (.rdp) files. When opening an .rdp file, all connection parameters are now displayed before the connection is established, and they are disabled by default. When opening such a file for the first time, a security warning also appears.
• Secure Boot certificate update status. In Windows Security (Settings > Privacy & Security > Windows Security), the status of Secure Boot certificate updates may now be displayed. The system shows notifications and status icons. On commercial devices, this feature is disabled by default.
• Precise detection of compatible devices for Secure Boot. As part of the Windows quality update, additional data has been added to precisely identify compatible devices. This expands the list of devices that can automatically receive new Secure Boot certificates. Certificates are installed gradually — only on devices where successful updates have been recorded, ensuring controlled rollout.
• Fix for BitLocker recovery issue. Fixed an issue that could cause the device to enter BitLocker recovery mode after Secure Boot updates.
