Windows 10: How can I check if the windows defender hasn't been tampered with?

I've noticed that after pausing updates and resuming them, the security intelligence update for defender managed to "downgrade?" itself from version 1.375.596.0 to 1.375.581.0 and today it updated itself to version 1.375.639.0 which is presumably the latest. This is a brand new Windows install. I've also noticed that the browsers sometimes redirects me to the linkhttps://www.microsoft.com/en-us/wdsi/defenderupdates that lists 1.375.633.0 as the latest update and one page lists 1.375.639.0 as the latest update, even if I refresh them. App & Browser control seems to be turned off for

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.
