Showing hidden devices

What stays hidden

Two groups are hidden normally: non-present devices, which Windows remembers from earlier connections, and some system components marked as hidden by their drivers. Microsoft documents the menu option that reveals them.

Non-present devices appear with faded icons. A USB adapter you used last month, or a monitor at a previous desk, may still be remembered so that its settings are ready if it returns.

Steps

Turning on this view only changes what is displayed.

1. 01
   Open Device Manager.
2. 02
   Open the View menu.
3. 03
   Select Show hidden devices.
4. 04
   Expand categories and look for faded icons.
5. 05
   Use View and Show hidden devices again to return to the normal view.

Reading what appears

Faded entries are expected and generally harmless. Several faded copies of the same device often mean it was plugged into different ports, because each connection point can create its own device instance.

Removing remembered entries is not necessary for normal use, and doing so without understanding them can remove settings you wanted. This guide stops at viewing; treat the list as a history rather than clutter.

Good to know

The setting applies only to the current Device Manager window. Close and reopen it and the default view returns, so there is no lasting change to undo.

Some hidden system components, such as software-only devices created by Windows itself, appear in categories like System devices or Software devices once revealed. These are part of how Windows organises its own services and are not physical hardware you need to locate.

If you are counting how many times a particular device has been connected in different places, the faded entries offer a rough tally, since each new connection point can add one.
