Windows 10: Should I Turn on Tamper Protection in Windows Security?

I just noticed in my Windows Security that everything was automatically on except tamper protection. Should I turn it on and will it do a lot of changes to my computer?

Tamper protection in 1903?

No. Tamper protection means you can only make changes from within the Windows Security app. You can still turn off real time protection in the Windows Security app while tamper protection is in force.

 

Tamper Protection missing from Windows Security in Windows 10 Pro

Hey there,

Tamper Protection is a security feature that was introduced in Windows 10 version 1903, otherwise known as the May 2019 Update. When enabled, Tamper Protection prevents Windows Security and Windows Defender settings from being changed by programs, Windows command
line tools, Registry changes, or group policies.

This is a good feature so it doesn't allow malware to override Windows Security and Defender.

To enable Tamper Protection do the following:

Are you using third-party anti-virus software?

 

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.
