RealPlayer and/or WMP

I had read somewhere on the forums here that it is not possible to create a portable app for Windows Media Player, as it is connected too closely to the operating system. I had also heard that if I wanted a media player so badly that I should just use VLC. I need a media player that I can distribute widespread throughout my high school on flash drives - my classmates and I exchange much forbidden content and get away with whatever we can hack. My school has a large network of computers, somewhere around 600. They have all been stripped of all but the most basic programs, such as calculator, ms paint, Google chrome, etc. This is incredibly annoying when it comes to projects that involve editing pictures or displaying videos. I have photo editing software, now, anyway, VLC is fine, but makes multitasking impossible, as the music glitches out for a few seconds with every click or push of keys: it's hard to explain. Also, all of the different versions of VLC that I have tried (I have tried all of them) are incapable of playing videos. I was hoping that somebody could produce a portable app for RealPlayer or WMP, my two favorite media players, for me. if not either then some similar program. If there is something wrong with my request or if you are unsure of something, please, do not hesitate to speak up. I primarily browse on Chrome. Thanks!
