KB5134130: Overview with user sentiment and feedback
Last Updated October 27, 2026
Probability of successful installation and continued operation of the machine
Overview
KB5134130 is an out-of-band, non-security cumulative update for Windows 11, version 23H2 (OS Build 22631.7654), released October 26, 2026. It targets devices that cannot receive current certificate trust list (CTL) updates, such as disconnected environments or systems with automatic CTL updates disabled. It requires the July 8, 2025 or later update to be installed first, and the latest SSU.
General Purpose
- Delivers an updated trusted root certificate payload for devices that cannot reach Microsoft's certificate-update service
- Includes all fixes from the October 13, 2026 update (KB5126653, Build 22631.7652)
- Bundles servicing stack update KB5126652 (22621.7641)
- Requires the latest SSU and a prior update released on or after July 8, 2025
- Dynamic update deployments must include the boot.stl file to avoid error 0xc0430001
General Sentiment
No substantive community discussion was available in the provided sources, so reception is unknown. Microsoft reports no known issues, and the update is aimed at a narrow audience (devices without access to CTL updates), so most standard 23H2 devices have little reason to install it.
