Summary: Microsoft released an emergency out-of-band update, KB5085516, on March 21, 2026, to fix a sign-in breakage introduced by the March Patch Tuesday cumulative update KB5079473. The bug caused Microsoft account sign-ins to fail across Teams, OneDrive, Edge, Excel, Word, and Microsoft 365 Copilot — even on devices with a working internet connection.

What happened: After installing KB5079473 (released March 10, 2026 as part of Patch Tuesday), affected Windows 11 devices entered a broken network connectivity state that caused any Microsoft account authentication attempt to fail with the misleading error: “You’ll need the Internet for this. It doesn’t look like you’re connected to the Internet.”

Today Canonical announced the release of Ubuntu 24.04 LTS, codenamed “Noble Numbat”, available to download and install from https://ubuntu.com/download.
