Microsoft has released an update for an issue with USB devices that occurred after the release of a security update for Windows 10. During the Patch Tuesday of February several cumulative updates were released, of which KB4074588 caused issues.
The update was released to fix several vulnerabilities in the Microsoft Scripting Engine, Edge, Internet Explorer, Windows Search, Windows Kernel, Windows Authentication, Device Guard and several other components. However, after the update was installed on Windows 10 systems, some USB and onboard devices, like a built-in webcam, keyboard or mouse, no longer worked.
The issue, which only occurred on Windows 10 systems with the Fall Creators Update (build 1709) applied, was caused by the installation of new drivers that were part of the update. Windows Update would in some cases skip the installation of new drivers and while it deleted the already installed drivers.
