  1. Worked for me,m it’s been bugging me for a few months, finally some relief! Thank you so much all the geeks that helped with this problem!

  2. Such a shame MS decided to be mean to its users by not adding an option to do it right away. I get security concerns, but come on, MS! The newer the Windows, the less control the end user has on it.

    Thanks for the instructions! 🙂

  3. At the very beginning, you say:
    Method 1
    1. Open This PC.

    OK, but how do I “open this PC”? Is it a file somewhere? Is there an icon to click on? Where is the “open” command?
    Would help if you said “Open This PC by clicking on…found in…” or whatever. There are guys like me who don’t even know that much.

  4. thanks Dexter. this one works!
    C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service .
