Microsoft has rolled out the KB5055523 update for Windows 11, introducing a host of fixes aimed at enhancing user experience and addressing various bugs that have plagued the operating system. Among the notable improvements is a resolution to a frustrating flaw in Explorer that rendered the context menu nearly unusable, a relief for many users who rely on this functionality.
Enhancements and New Features
This update is not just about fixes; it also brings exciting new features, particularly for users of Copilot+ PCs. For those who eagerly embrace early updates, the KB5055523 serves as the official security update following last month’s preview version (KB5053656).
In addition to the Explorer fix, the update improves the reliability of ctfmon.exe and addresses a critical issue where Kerberos authentication could become unresponsive under specific conditions when using RC4 encryption.
For Copilot+ PC users, several noteworthy enhancements have been introduced:
- New! The improved Windows Search feature makes it easier to find documents, photos, and settings. With the integration of semantic indexing alongside traditional lexical indexing, users can simply type what they are looking for without needing to remember exact file names or settings. This functionality is available even offline, thanks to the advanced capabilities of the 40+ TOPS NPU in Copilot+ PCs. Currently, this feature is available on Snapdragon-powered devices, with support for AMD and Intel-powered models on the horizon.
- New! Locating cloud-stored photos has become more intuitive. Users can search using natural language, such as “summer picnics,” and results will include both local and cloud-stored images. This feature works seamlessly with OneDrive when users are signed in with their Microsoft accounts.
- New! Enhanced communication capabilities are now available on AMD and Intel-powered Copilot+ PCs, featuring live captions and real-time translation for over 44 languages during video calls and streamed content.
- New! For Snapdragon-powered Copilot+ PCs, real-time translation into Simplified Chinese is now supported, alongside a wide array of other languages, enhancing global communication.
Microsoft has also highlighted several critical updates within this release:
- [Authentication] The update resolves an issue affecting machine password rotation in the Identity Update Manager, particularly when Kerberos is utilized with Credential Guard enabled, which could lead to authentication challenges for users. Consequently, the feature Machine Accounts in Credential Guard has been temporarily disabled until a permanent solution is implemented.
- [Daylight Saving Time (DST)] An update has been made for the Aysen region in Chile to accommodate the government’s DST change order set for 2025. For further details, users can refer to the Daylight Saving Time & Time Zone Blog.
- [PcaUiArm] This update addresses an issue that caused unexpected behavior in the PcaUiArmUpdate feature under certain scenarios.
As a security-focused update, KB5055523 will be automatically installed, ensuring that users benefit from these enhancements and fixes without the need for manual intervention.
