Known Issues and Workarounds​

Even meticulously crafted updates may come with a hitch or two, and Microsoft is transparent about a couple of known issues affecting specific user groups.

Roblox Functionality on Arm Devices​

• Issue: Users on Arm devices are encountering difficulties downloading and playing Roblox from the Microsoft Store.
• Workaround: Roblox recommends that affected users bypass the store by downloading the application directly from the official Roblox website until a permanent fix is provided. This clear workaround ensures that even under unexpected circumstances, users can continue enjoying their games without disruption.

Citrix Compatibility Concerns​

• Issue: A subset of devices with certain Citrix components—specifically those with Citrix Session Recording Agent (SRA) version 2411—might experience incomplete installation of the January 2025 security update. The update process might initially appear to succeed, only to trigger an error upon restart that reverts changes.
• Workaround: Citrix has provided documented guidance, advising IT administrators to perform a pre-update workaround to mitigate this issue. Although this problem appears limited to organizations using the specified Citrix component, it serves as a reminder of the complexities encountered when integrating third-party applications with Windows updates.

These scenarios underscore a broader challenge: while cumulative updates provide broad compatibility and improved security, third-party integration and specialized hardware configurations sometimes require tailored solutions. Microsoft’s proactive stance—issuing transparent documentation and collaborating with partners like Citrix—ensures that users are never left stranded when issues arise.

Installation Methods​

1. Automatic Update Channels:
   • Windows Update and Microsoft Update provide the easiest route for most users. The update downloads and installs automatically, synchronizing with your configured policies.
   • WSUS (Windows Server Update Services): Organizations can automate the process across devices using WSUS, ensuring that the correct update classifications (Product: Windows 11; Classification: Security Updates) are applied.
2. Manual Installation:
   For more controlled environments or offline updates, you can download the standalone package(s) from the Microsoft Update Catalog. The package typically contains one or more MSU files that you can install using the Deployment Image Servicing and Management (DISM) tool.
   • For a Running Windows PC:
     • Open an elevated Command Prompt and run:
       DISM /Online /Add-Package /PackagePath:c:\packages\Windows11.0-KB5053598-x64.msu
     • Alternatively, from Windows PowerShell:
       Add-WindowsPackage -Online -PackagePath "c:\packages\Windows11.0-KB5053598-x64.msu"
   • For Offline Installation or Mounted Images:
     • Mount your Windows image and apply the update using DISM:
       DISM /Image:mountdir /Add-Package /PackagePath:Windows11.0-KB5053598-x64.msu
     • Or via PowerShell:
       Add-WindowsPackage -Path "c:\offline" -PackagePath "Windows11.0-KB5053598-x64.msu" -PreventPending
