Hi Brian,
i would like to share my observations.
1. If I monitor a registry value of type String, then I'm able to get the logs.
2. If I monitor a registrey value of type DWORD, then I'm not getting any logs.
So when i checked the help document, it has following line written in the desciption,
"The data is treated as a string and not a number. For example, you might create a registry key condition with the name AAA and a registry key value of 111. If you configure the rule to block, then the rule only blocks AAA when it is created as a string."
So it seems that it only monitors the key value of a type string and not a number....
