Formerly known as the "news and interests" feed, the Windows 11 Widgets Board has undergone a "less is more" redesign.
This is usually a cache issue.
Do you want a clean sidebar without the noisy news articles?
Pro tip: If you miss the old "desktop gadgets," download – it restores classic CPU/RAM meters to Windows 11.
The "Windows 11 sidebar" is no longer just one static panel; it has evolved into a dynamic system of AI assistants, glanceable information, and productivity tools. As of mid-2026, Microsoft has significantly overhauled these side-mounted interfaces to prioritize AI integration through Copilot while streamlining the often-criticized Widgets board.
Microsoft is currently testing – third-party widgets from apps like Spotify, WhatsApp, and Discord that will live directly in the sidebar. Expect this update in late 2025.
