Windows 10: Unknown Drives in Device Manager

  1.    20 Jul 2017 #1

    Unknown Drives in Device Manager recently noticed that ALL of my computers drives are listed as "Unknown" in Device Manager. I've checked in Properties to upgrade drivers only to be informed that the "best drivers for this device is already installed" against all the drives including HDD's, SSD's and USB drives. the machine runs fine and in Disk Management they are all listed as they should be. Has anyone experienced a similar problem? All hard drives appear in the BIOS as they should.
