Program Manager - Can I use it to only monitor select installations?

Hello!

First off, thanks for making software, I’ve liked your other products (AV, firewall).

Quick question about Program Manager:

I’d like to use this software to manage installations, but only select installations. I don’t like to have too many processes running in the background, and I don’t need information stored about every program/update I install. I would like to occasionally monitor suspect software so that I can remove it entirely if it does anything creepy. I’m especially concerned about my registry, although come to think of it, does Program Manager also monitor all files created/modified by an installation? Would be useful if software suspiciously drops or modifies files outside its installation directory/user directories.

In the case that Program Manager must always be running, what kind of storage/memory footprint does it have?

Thanks for reading!
