M365 Changelog: REMINDER: Microsoft Edge to replace Microsoft Edge Legacy with the April Windows 10 Update Tuesday (or B) release

Petri Staff


MC250338 – As announced in MC237900 (February 2021), Microsoft is replacing the out-of-support Microsoft Edge Legacy application with the new Microsoft Edge as part of the April Windows 10 cumulative monthly security update, also known as the Update Tuesday (or “B”) release.

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.

If you do not set up kiosk mode in the new Microsoft Edge prior to applying the April Windows 10 Update Tuesday release, you will experience a disruption in your kiosk scenarios because Microsoft Edge Legacy and its kiosk mode will no longer be available.

What you need to do to prepare

If you already have the new Microsoft Edge on your device(s), and have set up any needed kiosk scenarios, no action is needed.
