Cyber: Windows 11 Kb5077181 & Kb5075941 Cumulative Updates Released

Microsoft has released Windows 11 KB5077181 and KB5075941 cumulative updates for versions 25H2/24H2 and 23H2 to fix security vulnerabilities, bugs, and add new features.

Today's updates are mandatory as they contain the February 2026 Patch Tuesday security patches for vulnerabilities discovered in previous months.

You can install today's update by going to Start > Settings > Windows Update and clicking on 'Check for Updates.'

You can also manually download and install the update from the Microsoft Update Catalog.

This is the third 'Patch Tuesday' release for version 25H2, but as it's based on version 24H2, there are no exclusive or special changes. You'll get the same fixes across the two versions of Windows 11.

After installing today's security updates, Windows 11 25H2 (KB5077181) will have its build number changed to Build 26200.7840 (or 26100.7840 in case of 24H2), and 23H2 (KB5073455) will be changed to 226x1.6050.

This update mostly contains bug fixes, and here's everything you need to know:

[Gaming] Fixed: This update addresses an issue that determines device eligibility for the full-screen gaming experience.

[Networking] Fixed: This update addresses an issue that prevented some devices from connecting to certain WPA3‑Personal Wi‑Fi networks. The issue might occur after you install KB5074105.

[Secure Boot] With this update, Windows quality updates include a broad set of targeting data that identifies devices and their ability to receive new Secure Boot certificates. Devices will receive the new certificates only after they show sufficient successful update signals, which helps ensures a safe and phased rollout.
