Might want to be careful doing this on your work computer. Your admin(s), if they are worth anything, will know youve been mucking around which would be grounds for termination and or criminal charges. I would suggest you either ask to have the programs installed or try to make friends with the admins, they may give you local power user rights.
You might want to ask yourself "is my job worth it". Unfortunately for many people in my company im the anal retentive asshole called the “security and compliance officer”. I spend my days looking for employees like you, building a case and pursuing criminal charges. I’m not trying to sound like a dick, just trying to give you fair warning. It's far better to get the rights in a legit manner.
