    Windows defender custom scan does not scan external drives

    I have Defender Windows 10. I tried using custom scan to select and scan external drives. The screen listing the drives comes up, but the "OK" button remains grayed out so unable to scan any of the drives listed. Any suggestions would be appreciated.

    Unable to run a scan in Windows Defender

    Defender not Running Regular Scan


    I've never understood the need some people feel to set up a scheduled task to run a Defender scan. For the past year the automatic maintenance has run Defender scans for me.

    That is, until the Anniversary Upgrade - it broke something and Defender never ran another scan. It finally alerted me that a scan was long overdue. I followed the suggestion on another thread...
    Windows Defender No Longer Performs AutoScan
    ...and the automatic maintenance scans are back to running regularly again.
