Windows 11 servicing stack update - 22000.1270
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 |
|---|
| IT admins | After installing this update, apps that use ODBC connections through Microsoft ODBC SQL Server Driver (sqlsrv32.dll) to access databases might not connect. Additionally, you might receive an error in the app, or you might receive an error from the SQL Server. Errors you might receive include the following messages:
- The EMS System encountered a problem. Message: [Microsoft][ODBC SQL Server Driver] Protocol error in TDS Stream.
- The EMS System encountered a problem. Message: [Microsoft][ODBC SQL Server Driver] Unknown token received from SQL Server.
To decide whether you are using an affected app, open the app that connects to a database. Open a Command Prompt window, type the following command and then press Enter:
tasklist /m sqlsrv32.dll
If the command lists a task, then the app might be affected. | We are working on a resolution and will provide an update in an upcoming release. |
How to get this update
Before installing 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

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.
