Note: Windows 10 19H2 users get quick access to an integrated feed of dynamic content such as Weather, Sports, News, and more directly on the Windows taskbar.

  • Users won’t get the Microsoft Edge Legacy application anymore installed by default on their devices. Instead, they will get the new Chromium-based Edge when they update their operating systems. 
  • Works upon a bug that fails to remove mandatory profiles when users sign out of their PCs after enabling the policy – “Delete cached copies of roaming profiles”.
  • No more Windows 10 activation issues even if you remove an owned operating system.
  • Improves an operation that evaluates the compatibility status of the Windows ecosystem. This is to ensure that all applications get proper updates and remain compatible. 
  • Works upon a race condition that usually occurs between Task Scheduler and the Workstation Service. Users may now join a hybrid Azure Active Directory (AAD) domain without getting into an error 0x80070490.
  • Improves the partial Service Connection Point (SCP) configuration so that dsregcmd.exe works normally. 

Other Fixes and Improvements

  • Earlier, when you disable the policy- “Register domain-joined computers as devices”, an issue appears from nowhere and triggers hybrid AAD joining automatically.

  • Addresses an anomaly that causes Azure Active Directory (AAD) Work Accounts to disappear unexpectedly from apps like Microsoft Teams or Microsoft Office.
  • Works upon an issue that results in a blue-screen error when Docker containers run with process isolation.
  • Corrects the issue that makes the automatic enrollment and certificate retrieval fail on error “The parameter is incorrect”.
  • Improves Task Scheduler so that it doesn’t cause monthly tasks and tasks scheduled for 0:00 UTC to occur at the wrong time.
  • Resolves a bug with Windows Virtual Desktop sessions. In this, a blank list of output devices appears when users plug in a new audio device during a session. 
  • Configures the speaker wizard so that it doesn’t behave mischievously. 
  • Users may now turn on the flashlight utility when the Camera application is in use.
