Microsoft has tried and tried again with some form of "widgets" for Windows. From all the way back to Desktop Gadgets in Windows Vista, the company has been working on various ways to introduce small bits of information in a contained visual style to Windows. They've been trying again with Widgets in Windows 11, so far consisting mostly of News and Weather widgets that provide a quick look at the latest updates (and provide a convenient link to help bolster Bing and Microsoft Ads numbers).
Adaptive Cars are built on a "universal card exchange network," and while the cards currently work on the Windows Timeline, Microsoft Teams, Outlook, Cortana Skills, and Microsoft's Bot Framework Web Chat, they can also be added to other networks, as Cisco has done with WebEx Teams.
So far, details are light on how developers will be able to introduce their apps in to Windows 11 Widgets and have them show up on the desktop, and Microsoft is promising more news "later this year."
