Improvements​

This non-security update includes quality improvements. Below is a summary of the key issues that this update addresses when you install this KB. If there are new features, it lists them as well. The bold text within the brackets indicates the item or area of the change we are documenting.

Gradual rollout​

These might not be available to all users because they will roll out gradually.

• [Task Manager]
  • New! The Disconnect and Logoff dialogs now support dark mode and text scaling.
  • New! The Performance section now shows the type for each disk.

A process that runs in an LPAC only has access to the resources it needs. The process does not have access to sensitive system components and data. This reduces the potential damage that a compromised process can cause.
• [DISM] Fixed: The StartComponentCleanup task does not work properly. It stops at 71% and shows error 6842.
• [PowerShell] Fixed: The Get-WindowsCapability command sometimes fails. Then you have to restart your PC.

Normal rollout​

• [HTML Applications (HTA)] Fixed: HTA optional components (OC) are now in ARM64 Windows PE.
• [Task Manager] Fixed: The Users page might cause Task Manager to stop responding when you use the keyboard.
• [Graphics Device Interface Plus (GDI+)]

Windows 11 servicing stack update (KB5048295) - 26100.2447​

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.

Known issues in this update​

How to get this update​

Before you install this update

Microsoft combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

Install this update

To install this update, use one of the following Windows and Microsoft release channels.


If you want to remove the LCU

To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.

Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.
