  • Thread Author
On December 10, 2024, Microsoft rolled out the KB5048667 update for Windows 11, specifically targeting users with the 24H2 version. With the release of OS Build 26100.2605, this update primarily addresses various security issues vital for maintaining a robust operating system. Let's delve deeply into what this release entails and how it impacts your computing experience.

Key Highlights of the KB5048667 Update​

1. Security Improvements​

The primary focus of the KB5048667 update is enhancing your system's security. It incorporates improvements that were initially part of the prior update, KB5046740, released on November 21, 2024. Microsoft emphasizes that these enhancements aim to bolster the internal functionality of Windows without introducing any new features.
  • Security Vulnerabilities: The update addresses critical vulnerabilities that could be exploited in real-world attacks, aligning with Microsoft's ongoing efforts to mitigate risks posed by cyber threats.

2. Importance of Servicing Stack Updates (SSU)​

Alongside KB5048667, the update package also includes a servicing stack update (KB5049685), which is crucial for ensuring that your Windows updates are installed reliably. The servicing stack is effectively the backbone of your update system, responsible for the installation of both cumulative updates and individual patches.
  • Why SSU Matters: A well-maintained servicing stack improves the update process's efficiency and reliability. Microsoft advises users to always ensure that their servicing stack is up to date before applying broader updates.

3. Known Issues​

As with many updates, there are certain known issues that users should be aware of:
  • Roblox on Arm Devices: Players using Arm devices might find themselves unable to download and launch Roblox via the Microsoft Store. Fortunately, an alternative exists: users can still access and play Roblox by downloading it directly from Roblox.com.

Installation Process​

How to Get This Update​

This update will download and install automatically via Windows Update. However, for those who prefer a more hands-on approach, you can also opt for manual installations using the following methods:
  • Windows Update: Simply navigate to Settings > Update & Security > Windows Update and check for updates.
  • Microsoft Update Catalog: For users seeking standalone packages, head to the Microsoft Update Catalog and download the required MSU files. It’s advisable to store all files in a single folder to facilitate smoother installation using Deployment Image Servicing and Management (DISM).

Command Line Installation​

For advanced users, you can utilize the command line to install updates directly. Here are the commands:
  • For a Running PC:
    Code:
    bash DISM /Online /Add-Package /PackagePath:c:\packages\Windows11.0-KB5048667-x64.msu
  • For Windows Installation Media:
    Code:
    bash DISM /Image:mountdir /Add-Package /PackagePath:Windows11.0-KB5048667-x64.msu

What's Next?​

While December’s update has a concentrated focus on security improvements, Microsoft has pointed out that normal monthly servicing will resume in January 2025, alongside the expected non-security updates. Users should stay tuned for any announcements on upcoming updates, bringing new features or enhancements.
