Windows 10 servicing stack update - 17763.4840

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

Using the FixedDrivesEncryptionType or SystemDrivesEncryptionType policy settings in the BitLocker configuration service provider (CSP) node in mobile device management (MDM) apps might incorrectly show a 65000 error in the "Require Device Encryption" setting for some devices in your environment. Affected environments are those with the “Enforce drive encryption type on operating system drives” or "Enforce drive encryption on fixed drives" policies set to enabled and selecting either "full encryption" or "used space only". Microsoft Intune is affected by this issue but third-party MDMs might also pe affected.

Important This issue is a reporting issue only and does not affect drive encryption or the reporting of other issues on the device, including other BitLocker issues.

This issue is addressed in KB5034127.

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.
