Error code 28 can apply to any hardware device in Device Manager, but seems to primarily affect USB devices and sound cards.

Any Microsoft operating system can experience a Code 28 Device Manager error, including Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and more. These instructions apply to all of those Windows versions.

Restart your computer, if you haven't already done so.

There is always a small chance that the Code 28 error you are seeing in Device Manager was caused by a fluke with Device Manager or your BIOS. If that is the case, a reboot may fix the problem.
