Improvements
This security update includes quality improvements. Below is a summary of the key issues that this update addresses when you install this KB. If there are new features, it lists them as well. The bold text within the brackets indicates the item or area of the change we are documenting.

• [Microsoft Defender for Endpoint] Fixed: Work Folders files fail to sync when Defender for Endpoint is on.
• [Input Method Editor (IME)] Fixed: When a combo box has input focus, a memory leak might occur when you close that window.
• [AppLocker] Fixed: The rule collection enforcement mode is not overwritten when rules merge with a collection that has no rules. This occurs when the enforcement mode is set to “Not Configured.”
• [Remote Desktop Gateway Service] Fixed: The service stops responding. This occurs when a service uses remote procedure calls (RPC) over HTTP. Because of this, the clients that are using the service disconnect.
