    If not, suggests deeper problems. To which uninstall option are you referring? (A picture is worth...)

    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.

    security scan

    Hi,

    It's possible that some corrupted system files are preventing Windows Defender from running a scan on your computer. we'd like to learn more about your concern so that we could provide the proper resolution. We just have a few questions for you:

    • Which build version of Windows 10 is on your computer? To check, click
      Start
      , type winver, and press Enter. For example, 14393.1066.
    • Did you make any changes to your computer before this happened?
    • What troubleshooting steps have you done so far?

    As initial recommendation, we suggest performing a clean boot to find out if this behavior is
    caused by a third-party program. This will load Windows with minimal drivers and programs, preventing software conflicts from occurring. If you can perform a security scan in a clean boot environment, check the section How to determine
    what is causing the problem by performing a clean boot
    for what to do next.

    Note: To return your computer back to normal, check the section How to reset the computer to start normally after clean boot troubleshooting.

    We'll wait for your response and the results of the initial troubleshooting.
