  • Addresses an issue that prevents some machines from automatically going into Sleep mode under certain circumstances because of Microsoft Defender Advanced Threat Protection (ATP) Auto Incident Response (IR).
  • Addresses an issue that prevents some machines from running Microsoft Defender ATP Threat & Vulnerability Management successfully.

Microsoft is working on a resolution and will provide an update in an upcoming release.

Devices using a manual or auto-configured proxy, especially with a virtual private network (VPN), might show limited or no internet connection status in the Network Connectivity Status Indicator (NCSI) in the notification area. This might happen when connected to or disconnected from a VPN or after changing the state between the two. Devices with this issue might also have issues reaching the internet using applications that use WinHTTP or WinInet. Examples of apps that might be affected on devices in this state include, but are not limited to, Microsoft Teams, Microsoft Office, Microsoft Office 365, Microsoft Outlook, Internet Explorer 11, and some versions of Microsoft Edge.

This issue is resolved in KB4554354.

Devices on a domain might be unable to install apps published using a Group Policy Object (GPO). This issue only affects app installations that use .msi files. It does not affect any other installation methods, such as from the Microsoft Store.

This issue is resolved in KB4549949.
