LOW
The severity is rated low due to the nature of the issue being more of a functionality glitch rather than a security vulnerability. However, it can disrupt user productivity and trust in Windows updates. Real-world exploitability is minimal as this does not provide an entry point for attackers. Patches are expected soon, reducing the window of exposure.

Microsoft has introduced a glitch in its recent updates for Windows 11 versions 25H2 and 24H2, affecting the sign-in functionality for Microsoft accounts across various applications such as OneDrive, Office, and Teams Free. The issue manifests as an erroneous message indicating that there is no internet connection when attempting to sign in, even if the device is actually connected. This error occurs due to a specific network connectivity state triggered by the update. For users experiencing this problem, Microsoft suggests restarting their devices while ensuring they are online, which may temporarily resolve the issue. However, if restarted offline, the problem might recur. The broader security implication here includes potential disruptions in user access and productivity, as well as trust issues with the reliability of Windows updates.
