  • Addresses an issue with syncing settings from the Accounts page when the “Continue experiences on this device” Group Policy is disabled.

  • Addresses an issue that prevents the Unified Write Filter (UWF) servicing mode of Windows Update from working with the Windows Server Update Services (WSUS) server.
