  • Addresses an issue to allow the use of the previous barrel button and drag functionality and ensure that shim choices have priority over the registry. 
  • Addresses an issue that causes Microsoft Word Immersive Reader to skip the first part of a selected word when using Microsoft Word Online in Microsoft Edge. 
  • Addresses an issue in the Universal CRT that sometimes causes the AMD64-specific implementation of FMOD to return an incorrect result when given very large inputs.

  • Addresses an issue with the Group Policy Object (GPO) "Prohibit connection to non-domain networks when connected to domain authenticated network”. In this scenario, this GPO disconnects the Wi-Fi interface over which a VPN client connection is established. 
  • Addresses a power state transition issue that causes the system to become unresponsive when connecting to eXtensible Host Controller Interface (xHCI) devices. 
  • Addresses an issue that causes the RemoteApp window to always be active and in the foreground after closing a window.
  • Addresses an issue that causes the installation and client activation of Windows Server 2019 and 1809 LTSC Key Management Service (KMS) host keys (CSVLK) to not work as expected. For more information about the original feature, see KB4347075
