    Defender Tamper Protection/1903

    Moderators: This thread deals with Defender Tamper Protection setting and 1903. If this would be better served in a different location, please feel free to move the post.

    Just wondering if anyone who installed 1903 is having any unusual issue with Defender's Tamper Protection.
    Here's the blow-by-blow.....

    1. Friend and I were running 1809 and installed 1903 via Update Assistant on Tuesday, May 21st. No issues and Defender Tamper Protection was on (default setting).
    2. Two days later, the 23rd, friend gets alert that Tamper Protection is off. She turned it on and it seems to be holding.
    3. Today, I get the alert Tamper Protection is off and I turned it on. So far, it's holding.

    I have no idea why Tamper Protection would turn off. Both computers are clean -- no viruses, trojans, malware or adware. We do not mess around in the registry and there is absolutely no third-party antivirus on either machine.

    For now, I'm taking a wait-and-see if Tamper Protection turns off again. I don't know if it's a 1903 bug or not. Any ideas or suggestions would be appreciated.

    Hello Pauly, *Smile

    It is recommended to leave tamper protection turned on to help prevent Windows Defender from being turned off from anything or anywhere other than directly from Windows Security.

    Defender Tamper Protection/1903

    Friend and I updated to 1903 May 21st and the tamper protection alert (for her and me) happened before we got KB4497935 and KB4497165. She also got the antimalware platform update and tamper protection alert a few days before I did. According to an MS blog, antimalware platform updates are monthly. Could it be possible that it went in on your system behind-the-scenes while updating? -- presuming it's the cause of the alert. After turning tamper protection on, it has stayed on and the other two KB's haven't affected it.
