Windows 10 servicing stack update - 20348.1066​

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​

SymptomWorkaround
After installing this update, file copies using Group Policy Preferences might fail or might create empty shortcuts or files using 0 (zero) bytes. Known affected Group Policy Objects are related to files and shortcuts in User Configuration > Preferences > Windows Settings in Group Policy Editor.
To mitigate this issue, you can do ONE of the following:
  • Uncheck the "Run in logged-on user's security context (user policy option)". Note: This might not mitigate the issue for items using a wildcard (*).
  • Within the affected Group Policy, change "Action" from "Replace" to "Update".
  • If a wildcard (*) is used in the location or destination, deleting the trailing "\" (backslash, without quotes) from the destination might allow the copy to be successful.
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 now 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.

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.
