So, basically I want to install some software (splashtop streamer) on a school computer so i can remotely control it through a mobile device but when i go to actually install the program it says something about me needing admin privilges to do so.....

that's a given. Time to play ninja and find out the secret code

Welcome to the wonderful world of Windows UAC (User account control)
Your only real option is to get Someones Admin Credentials. Or luck out if somebody with admin privileges forgets to log off or lock the computer before leaving.

>>3 The school would have set up user restrictions no matter the operating system, and all the more on Unix systems since sudoer pupils will wreck it in 5 seconds.

>>1 If the security at your school is loose enough, try to install the software on your own pc, copy the installation folder to an external drive (f***, I almost wrote floppy disk), and execute the client from the external drive.

But that's no stuff for school. Why do you want to use it ? You will just prevent some students who want to really work to use the PCs, and you will congest your school's network.

I know it sounds silly but try 0000 it worked fine for me. Especially if the admins in your school are older or bad with computers.

On some of the computers in my high school there wasn't even a password for one of the local admin account.

So, I regularly logged in as an admin to update most of the stuff. However, I once without meaning to do so allowed half the PCs of my high school to update their OS, and they had been installing them at the beginning and the ending of the practical works for weeks.
Should have one teacher learn it was because of me, I would have die. (^-^#)>

Also, a senpai had the admin credentials for an other area, and he also maintained this area secretly. The year he was gone, half the PCs in the library went out of order. (I'm not exaggerating on the ratio).

I have a great idea download vm(virtual machine) for the computer and open wit window and if u need permission for that I have a version from compute science class that overrides and runs unintuitive but if u find a way to put window in that tell me

If u want the virtual machine send email through mskkm.dollars@gmail.com
