Windows 11 KB5127648 & KB5126653 cumulative updates released

Microsoft has released the Patch Tuesday Windows 11 KB5127648 and KB5126653 cumulative updates for versions 26H2/25H2/24H2 and 23H2 to fix security vulnerabilities and bugs, and add new features.

Today's updates are mandatory as they contain the October 2026 Patch Tuesday security patches for hundreds of 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 tenth 'Patch Tuesday' release in 2026, and it's based on 24H2, which means 25H2 or 26H2 get the same update. There are no exclusive or special changes. You'll get the same fixes across the two versions of Windows 11.

With today's update, Microsoft is adding new emojis to Windows 11 and fixing minor issues with File Explorer.
