Those schools with a good IT background (has FTP for students e.g.) would usually set Software Restriction Policies
on the computers to limit students (in forms of Games, malicious software or hacking). The main thing that students get irritated at is the inability to play games on the school computers. Of course, when you are supposed to do work, you'd better do so. There is also the frustration of not being able to run productivity applications (e.g. notepad++). Then there are also offices which have them. I shall not elaborate, as I am a mere student. The troubles are, however, still similar.
I will demonstrate a generic method to get past the SRP, and some short cuts and tips to improve speed and efficiency. I AM NOT LIABLE FOR YOUR USE OF THIS INSTRUCTABLE
UPDATE: For speedy tips, go to step 4.
