    Q: re Windows Defender\mpcmdrun.exe


    Hello Ten,
    I run third party AV. So, Windows Defender is off and Windows Defender Service is Manual -- not running.
    I'm wondering why I see > C:\Program Files\Windows Defender\mpcmdrun.exe called.
    I found > MpCmdRun.exe running, but I use a different antivirus, why? - Anti-Virus, Anti-Malware, and Privacy Software
    and I found > It's the Windows Defender Command Line Utility.
    Wondering, why does > Windows Defender\mpcmdrun.exe want to run. I've blocked thru blacklist.
    Curious, why the heck is mpcmdrun so persistent with Windows Defender not running.

    Most likely it's due to a scheduled task. Check your task scheduler (Windows>Windows Defender).

    No scheduled task for Windows Defender. And I have C:\Program Files\Windows Defender\mpcmdrun.exe blacklisted. I see stuff like dstokenclean, compattelrunner, dmclient and mpcmdrun called in my anti-executable event log. NoVirusThanks EXE Radar Pro is great fun. And at least one Bleeping member wanted to know too. Thanks

    By default, there are 4, unless you have Insider version. Also make sure to disable all its services (Wdfilter particulary).


    • schtasks /Change /TN "Microsoft\Windows\Windows Defender\Windows Defender Cache Maintenance" /Disable
    • schtasks /Change /TN "Microsoft\Windows\Windows Defender\Windows Defender Cleanup" /Disable
    • schtasks /Change /TN "Microsoft\Windows\Windows Defender\Windows Defender Scheduled Scan" /Disable
    • schtasks /Change /TN "Microsoft\Windows\Windows Defender\Windows Defender Verification" /Disable

      reg add "HKLM\System\CurrentControlSet\Services\Sense" /v "Start" /t REG_DWORD /d "4" /f (this one is in Insider)
      reg add "HKLM\System\CurrentControlSet\Services\WdFilter" /v "Start" /t REG_DWORD /d "4" /f
      reg add "HKLM\System\CurrentControlSet\Services\WdNisSvc" /v "Start" /t REG_DWORD /d "4" /f
      reg add "HKLM\System\CurrentControlSet\Services\WinDefend" /v "Start" /t REG_DWORD /d "4" /f
