Windows 10: Device Manager > Scan for hardware changes?

Since the first time I saw it in Windows (can't remember which version), long ago, I never had anything I could see as a result of clicking on the "Scan for hardware changes" option in the Device Manager.

What does it do exactly and is there any kind of file it generates? TIA.

Must scan device after each startup


I installed a dual serial port card in a PCIe slot in my Acer i7 desktop, Win 10 Home. It works until the computer is restarted, then device manager lists the ports as hidden and says they are not physically connected. If I right click the device and scan for hardware changes, they will work until the next time the machine is shut down and restarted. The manufacturer suggests putting them in a different slot, but that is not helpful as there is only one PCIe slot. Can anyone suggest a way of fixing this or, alternately, is rhere a way to force windows to scan devices for hardware changes at each startup? Thanks for any help.

Hi there, modernhistorian. Welcome to Windows TenForums.

Sounds to me like it may have not physically seated correctly in the slot, Try reseating it. Or Windows isn't retaining the settings in the Registry. Did you install, boot it up, and did Windows install a driver? It should have configured all that. Try uninstalling the device in Device Manager and reboot to see if that does it. Look in System Information to see if you can see any conflicts hardware wise.
