Sometimes the device manager just won’t open for whatever reason. This happened to me before and I don’t know why. Either way, this is how to do it without going to the control panel. This how-to involves the use of the Microsoft Management Console. I have no idea what it does, I just know that it will let me into the device manager.
- Start > Run (or winkey + r)
- Type “mmc” and click OK
- Click File > Add/Remove Snap-in…
- Select Device Manager from the left menu and click the Add button.
- Click OK
The device manager should now be visible in the left pane of the mmc window.
