Windows 11 Update KB5079473 Breaks Microsoft Account Logins, Patch Coming in Days

Microsoft expects to patch the issue within days after advising an online restart as a temporary workaround.

Overview

  • After installing KB5079473, affected apps show errors like “You’ll need the Internet for this” even when devices are online.
  • The bug disrupts Microsoft account sign-ins for OneDrive, Edge, Teams Free, Word, Excel, Microsoft 365 Copilot, the Xbox app, and the Microsoft Store.
  • Businesses using Entra ID (formerly Azure Active Directory) are not affected, with impact largely limited to consumer Microsoft accounts.
  • Microsoft’s mitigation is to restart the device while connected to the internet, noting that restarting offline can return the device to the faulty network state.
  • Microsoft says a fix is in development and due within days, and it has separately released out-of-band enterprise updates for Bluetooth visibility and RRAS security issues.
