    How to Show and Access Hidden and Ghost Devices and Drivers in Device Manager

    This will show you the devices and drivers from programs you no longer use, it will free up some disk space, not to mention help resolve potential conflicts between drivers that are no longer needed.

       Warning
    You do not want delete any Generic Volume Shadow Copy Drivers or Non-Plug and Play Devices before you make sure of their functions as you could disable the PC entirely or at the least some programs / apps will fail to function.

    Let's get started!


    1) In the Windows 7 start menu right click computer and select properties, in the "System" window that opens in the upper left pane select Advanced System Settings.

    Hi, yes of course!

    That's pretty handy when many devices had been plugged onto the computer...then, if you do not need them anymore, it free the place for other one!:)
