A portable app that can close other running portable apps upon ejection?

I have many apps on my flash drive. Oh, who am I kidding? I practically live off of it. Anyways I have the PA Platform and have set a few apps to run on start-up of the platform (AquaSnap, AIMP, WinPenguins, etc.)So I plugged my flash drive into a school computer that has Windows 7 installed and has no Quick Start Menu and has task manager restricted. I forgot at the time and thus opened WinPenguins. A few minutes later, my Web Design class started. I tried every possible way I could think of to try and exit the program, but to no avail. In the end, I had to restart the computer. Penguin infestation may seem unimportant to you, but if you have AD-HD and a bunch of penguins are running around your desktop and exploding and making sount effects, it gets hard to concentrate. So, I just need a way to close programs like this without using task manager when I need to eject my flash drive automatically. If someone could suggest a portable app that would help, please do. I AM DESPERATE! Thank you in advance!
