Background activity moderator (BAM)
The Background Activity Moderator (BAM) key seems to have been introduced in Windows 10 after version 1709.
The BAM keys can be found in the following Registry paths:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\bam\UserSettings\
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\bam\State\UserSettings\
Within the UserSettings key, there is a key for each user SID containing a value for each tracked executable.
