Using Device Manager

To start Device Manager, in File explorer, right-click This PC, click Manage, and then select Device Manager from the System Tools that are listed in the resulting dialog.

Device Manager displays information about each device. This includes the device type, device status, manufacturer, device-specific properties, and information about the driver for the device.

If your device is required to start the computer, a problem with your device installation can prevent the computer from starting. In these cases, you have to use the kernel debugger to troubleshoot your device installation. For more info, see Getting Started with WinDbg (Kernel-Mode).

If your device is not required to start the computer, Device Manager places a yellow exclamation point next that device's name in the Device Manager dialog. Device Manager also provides an error message describing the problem. For more information about the error messages, see Device Manager Error Messages.

Device manager can show hidden devices. This is helpful when you are testing the installation of a new PnP device. For more information, see Viewing Hidden Devices.

Device Manager provides detailed information in the Properties dialog for each device. Right-click the name of the device, and then click Properties. The General, Driver, Details, and Events tabs contain information that can be useful when you debug errors. For more information, see Device Manager Details Tab.
