Device Manager usually lists COM ports for desktops. However, those COM ports can sometimes disappear from the Device Manager window after users upgrade their Windows platforms. Users then wonder where their COM ports have gone. Thus, some users need to restore missing COM ports so they can configure them via Device Manager.
How can Users Restore Missing COM Ports?
1. Select the Show Hidden Devices Option
- First, try selecting the Show hidden devices option. Open the Win + X menu with the Windows key + X keyboard shortcut.
- Click the Device Manager option on that menu.
- Then click the View menu in Device Manager.
- Select the Show hidden devices option.
2. Add COM Ports
- Some users have restored missing COM ports by selecting the Add legacy hardware option to add COM ports. To do that, open Device Manager in Windows.
- Click the Action menu.
- Select Add legacy hardware to open the window shown directly below.
- Press the Next button on that window.
- Select the Install the hardware that I manually select from a list radio button.

3. Update Motherboard Drivers
Some users might need to update antiquated motherboard drivers to restore missing COM ports in Device Manager. Users can do that manually or with Driver Booster 7, which will scan for devices and components that need driver updates. To add DB 7 to Windows, click Free Download on the Driver Booster 7’s page.
After installing and opening Driver Booster 7, it will scan when launched. The software will then display a list of antiquated device drivers that it can update. Click the Update Now button if the scan shows that motherboard drivers need updating.
