Almost every piece of hardware attached to your Windows computer will show up in Device Manager as an installed device. This includes s, CPUs, USB devices, disk drives, network adapters and just about anything else. When the device is first connected to the computer, Windows will pick it up and either automatically or you install it yourself from CD or the internet.

After that, it’s not a problem while the device remains connected but can potentially become a problem. The driver that was installed when the new hardware was connected does not get uninstalled when the hardware is removed. Over time this can leave dozens of driver entries on the system for devices which have long since been removed. Some applications also do the same and install a software driver but don’t remove it when you.

Even if the hardware or software is no longer available, Windows will still look for it on boot. This can and potentially cause future driver conflicts so it makes sense to remove what is no longer required.

Nirsoft DevManView DevManView is an alternative tool to the Windows Device Manager, but it displays a whole lot more useful information. Like all Nirsoft tools, DevManView is small, portable and packs a lot into its small size. Before viewing and removing any devices it’s a good idea to first change a couple of settings so things are easier to see. Go into the Options menu and enable Mark Connected Devices and Show Non Plug and Play Drivers, then click on the Connected column header to sort the list by which devices are connected and which aren’t.

Then click, Shift+click or Ctrl+click to select the required devices and go to File > Uninstall Selected Devices. Devices can be disabled instead of removed for troubleshooting purposes. Command line options are also available, /uninstall and /use_wildcard being the most useful for the purpose of removing unused and hidden devices. Device Remover In terms of a third party device management application, Device Remover is probably the most advanced and feature rich free program available.

Sadly for some reason the program is no longer developed and the official website has disappeared. The last available version is from 2014 so is new enough to work fine for most people. Both portable and installer versions can be downloaded.

During first run you will be asked if you want to let the program run an optimize routine, allowing it should speed up the device detection and enumeration process. Once loaded, devices can be viewed in a tree or list style, selectable from the tabs. To switch to showing only hidden devices click Display Mode on the toolbar and select Show only hidden/detached devices. From there it’s a simple process of looking through the devices and checking the boxes of any to remove, then click Remove all checked when ready. A device removal warning and confirmation window will appear to give you one last opportunity to back out of the changes.
