The update affects Active Directory domains that host mobile device management (MDM) providers. They can transition from “Compatibility mode” to the strong certificate mapping “Enforcement mode.” To do this, they can allow an Active Directory Key Distribution Center (KDC) to read user security identifiers (SID) from the Subject Alternative Name (SAN). Then, the providers can populate those values. To learn more, see:

Windows 10 servicing stack update - 17763.5568
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 |
|---|---|
|
Following installation of this update, Local Security Authority Subsystem Service (LSASS) may experience a memory leak on domain controllers (DCs). This is observed when on-premises and cloud-based Active Directory Domain Controllers service Kerberos authentication requests. Extreme memory leaks may cause LSASS to crash, which triggers an unscheduled reboot of underlying domain controllers (DCs). |
This issue is addressed in KB5037425. |
How to get this update
Before installing this update
Microsoft now combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.
Prerequisite:
You must install the August 10, 2021 SSU (KB5005112) before installing the LCU.
