What you need to know:
Microsoft Edge Legacy (the rubbish one) support will end on March 9, 2021. It will not receive new security updates.
What you need to do:
To continue using a supported browser, transition to the new Microsoft Edge (personally, I use Edge for work and Chrome for play). If you don’t do this, an optional Windows update will take care of the upgrade for you, learn more about that here: New Microsoft Edge to replace Microsoft Edge Legacy with April’s Windows 10 Update Tuesday release.
Availability
Support will end on March 9, 2021.
