As I understand, you review products based on a number of aspects, a set number of challenges so to speak, in which they must pass to attain a positive score.
Regarding Behaviour Monitoring (Non-interactive) -
I cannot say for MSE, but in WD the Behaviour Monitor is enabled by default in Windows 8.1, although there are no visible settings from the GUI. However, considering the similarities between the two, I'd say it would apply to MSE too.
Regarding Windows Firewall -
Multiple Services will use the same svchost.exe process, so remember to check the PID in Task Manager and then exclude the usage amount. (See example below). Despite that, RAM usage of this component in Windows is negligible.
Overall, I've been using Windows Defender (Windows 8/8.1) for the past 2 years, which is essentially identical to MSE and haven't come across a threat that has bypassed it's protection. So while I do utilise UAC and SmartScreen, even without them (ie. Vista, 7), MSE/WD is still a suitable AV that I would rate from a 'Good 3 stars' or above.
