Windows 11 Update Fix Restores Network and Device Functions

21 Oct 2025

Microsoft is rolling out a patch to fix issues from a recent Windows 11 update that disrupted network and device operations. Users reported broken HTTP/2 connections, non-functional Logitech devices, and problems with File Explorer.

Network and Device Disruptions

The update pushed in October caused local applications relying on HTTP/2 to lose network connectivity. Additionally, some Logitech peripherals stopped working, and File Explorer's Preview pane failed to display documents due to a security error.

  • The update affected 127.0.0.1 HTTP/2 connections.
  • Logitech devices experienced failures in WinRE (Windows Recovery Environment).
  • File Explorer's Preview pane was rendered dysfunctional.

Patch Release Timeline

Microsoft assures users that the patch is being distributed, though it may take up to 48 hours to be widely available. The issues arose shortly after Microsoft concluded support for Windows 10, leaving many users reliant on Windows 11.

Impacted Software and Devices

The update affected locally hosted apps, various Logitech devices, and elements of File Explorer. Microsoft has emphasized the importance of checking for updates to ensure these functionalities are restored.

The sudden timing of these issues, concurrent with the end of Windows 10 support, posed challenges for users; however, Microsoft is addressing the problems promptly.
