• Support for the Microsoft Edge Legacy desktop application ended on March 9, 2021.
• When you apply this update to your devices, the new Microsoft Edge will be installed and the out-of-support Microsoft Edge Legacy will be removed.
  • Please review which Windows 10 versions are affected.

When this will happen

The April Windows 10 Update Tuesday release will be available starting April 13, 2021.

How this will affect your organization

When you apply this update, the out-of-support Microsoft Edge Legacy desktop application will be removed, and the new Microsoft Edge will be installed.
