Hacking with Windows (Hypothetical)

I saw a recent post asking how to hack with windows, to which (no surprise) people instead recommended using kali. I'll admit, Windows is not the optical hacking system, mainly because it was not even designed for that. However, in my current position irl, I cannot exactly shred my (school) OS and replace it, since that is generally frowned upon in that professional establishment.

So what should someone do when their PC has all of its external ports blocked, unable to install a new OS, and are confined to Windows?

(Post any scattered thoughts below. This is merely hypothetical.)

I just use security and permission flaws that come with downloading new programs.
