[Windows] Private Key file as a Temporary file is accessible by every user by default

Note: SYSTEM is the highest privileged user on Windows. You seem to have it mixed up with Everyone?

Not at all, I was just kind of miffed that one of my private key file was accessible to every user on my system (Which is me and my brother) in some temp folder.

It's not that it's an actually issue, but shouldn't private key files be only accessible to its owner?

Your screenshot does not show which privileges each of those users has, though. What do the privileges for Arian and Willy look like?
I recommend looking in the advanced settings.

I tried reproducing this. I created an additional local user and turned on that option to save the attachment to a temporary file.
The "KeeAgent" folder in my %temp% folder, as well as the temporary file within it, exclusively have inherited permissions, no explicit ones:

No sign of the other user I created.

Most likely, you granted access to the other user at some point in the past.
