Meet Now is a new icon that you may see in your taskbar if / when you install the Windows 10 20H2 update. Don’t worry, it is suppose to be there.
This little icon is a new Skype feature that Microsoft hopes will take on Zoom for meetings.
Other features include:
Start Menu with theme-aware tiles, which means backgrounds can blend in.
ALT + TAB support and other improvements for Microsoft Edge, Now called Chromium Edge
Changes to notifications to further annoy you
Changes to Settings which means you may not be able to find what you are looking for
And a few other things including someting called Modern Device Management which I may say more on when I understand it.
