There’s nothing quite as frustrating as opening Device Manager to troubleshoot a driver issue, only to watch the window flicker and refresh every few seconds. You can’t click on a device, you can’t read the error codes, and you certainly can’t uninstall a driver.

If your Windows Device Manager is stuck in a constant refresh loop, you aren’t alone. This is a surprisingly common glitch. Here is why it happens and, more importantly, how to stop it. Device Manager refreshes automatically when Windows detects a hardware change . It is designed to do this so you can see new devices appear or disappear in real-time.
