Windows 10 servicing stack update - 20348.610
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
|
Symptom |
Workaround |
|---|---|
|
After installing updates released January 11, 2022 or later, apps that use the Microsoft .NET Framework to acquire or set Active Directory Forest Trust Information might have issues. The apps might fail or close or you might receive an error from the app or Windows. You might also receive an access violation (0xc0000005) error. Note for developers Affected apps use the System.DirectoryServices API. |
To resolve this issue manually, apply the out-of-band updates for the version of the .NET Framework used by the app. Note These out-of-band updates are not available from Windows Update and will not install automatically. To get the standalone package, search for the KB number for your version of Windows and .NET Framework in the Microsoft Update Catalog. You can manually import these updates into Windows Server Update Services (WSUS) and Microsoft Endpoint Configuration Manager. For WSUS instructions, see WSUS and the Catalog Site. For Configuration Manger instructions, see Import updates from the Microsoft Update Catalog. For instructions on how to install this update for your operating system, see the KB articles listed below:
