  2. Error: "You require permission from SYSTEM to make changes" while deleteing files and folders in Windows 10

    Please try the takeown.exe and icacls.exe command-line method to assign permissions.

    Run:

    • takeown /f "C:\ProgramData\Microsoft\Windows Defender\scans\History\Service\DetectionHistory" /a /r /d y
    • icacls "C:\ProgramData\Microsoft\Windows Defender\scans\History\Service\DetectionHistory" /grant %username%:F /T
    • rd /s /q "C:\ProgramData\Microsoft\Windows Defender\scans\History\Service\DetectionHistory"

    Clearing Windows Defender history

    Hey, what you need to do is so simple, just follow the steps below exactly in order:
    1. Turn OFF Real-time Protection
    2. Turn OFF Cloud-delivered Protection
    3. Go to this folder C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service
    4. Delete the contents in the folder
    5. Turn ON Real-time Protection
    6. Turn ON Cloud-delivered Protection
    That's it... Now check protection History, it's empty.
    Done!
