Windows 11 servicing stack update - 22000.345​

• 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​

Applies to	Symptom	Workaround
All users	After installing Windows 11, some image editing programs might not render colors correctly on certain high dynamic range (HDR) displays. This is frequently observed with white colors, which could display in bright yellow or other colors. This issue occurs when certain color-rendering Win32 APIs return unexpected information or errors under specific conditions. Not all color profile management programs are affected, and color profile options available in the Windows 11 Settings page, including Microsoft Color Control Panel, are expected to function correctly.	We are working on a resolution and estimate a solution will be available in late January.
IT admins	After installing this update, IP Security (IPSEC) connections that contain a Vendor ID might fail. VPN connections using Layer 2 Tunneling Protocol (L2TP) or IP security Internet Key Exchange (IPSEC IKE) might also be affected.	To mitigate the issue for some VPNs, you can disable Vendor ID within the server-side settings. Note Not all VPN servers have the option to disable Vendor ID from being used. We are presently investigating and will provide an update in an upcoming release.

How to get this update​

If you want to remove the LCU

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.
