Microsoft has a quality control problem. Right now, Windows 10 updates are a minefield with some updates causing more problems than they fix. And now new warnings suggest Microsoft’s latest Window 10 updates might be one of the worst, Forbes reported.

The September KB4515384 update is already a menace. Introduced to fix CPU spiking, reports state it has broken Windows 10 search, the Start Menu, Action Centre, USB connections and caused audio problems. And now it is gunning for your Internet access.

Windows Latest has spotted that users are reporting on Microsoft’s community forum, Windows 10’s Feedback Hub and social networks that network adapters have stopped working after applying this update. Impacted users primarily appear to have Intel chipsets (Asus, MSI and Gigabyte motherboards are mentioned) and both their Ethernet and WiFi connections are affected.

“Cumulative update (KB4515384) causes the NIC to fail to enable with a code 10 error,” warns one user on the Windows 10 Feedback Hub. “Reinstalling network drivers from Intel or Windows Update sources does not resolve the issue. However removing the update through the ‘Programs & Software’ panel or using a recovery point set *before* the update fully resolves the issue.”

“KB4515384 breaks ethernet and wifi adapters on my PC,” explained another on the Hub. “Appears to create new devices as they’re labelled ‘#2’ and when exposing hidden devices in Device Manager the previously named devices appear. Uninstalling these / new or old drivers do not fix the issues (i.e. ‘ethernet unplugged’ which it is clearly not). Only option was to uninstall this update.”

For its part, Microsoft has confirmed a new bug in Windows 10 1903 which can knock-out WiFI on Intel and Broadcom wireless cards but claims it is limited to NEC devices. So whether it is connected or another new WiFi issue, remains to be seen.

Needless to say, hopes will be high that Microsoft can issue a patch quickly but the bigger issue is whether you will trust that patch given. In the meantime, Microsoft continues to forcibly upgrade users to Windows 10 1903.
