Device Manager is a component of the Microsoft Windows operating system.

On Windows 9x, Device Manager is part of the System applet in Control Panel.

If Windows recognizes a problem with a device, it is denoted by a black exclamation point (!)

This is useful for note-taking and for reporting problems to remote third parties such as technical support personnel.

The program has switches to control the output detail and format, including an /fo switch with csv parameter to generate output in comma-separated values format, suitable for importing into a spreadsheet application such as Microsoft Excel.
