Get information about staff and students! Part1

I took it from the beginning .... My plan is NOT to represent, or to communicate essential information about yourself or someone else's data. I am a high school student with a focus in IT, thankfully this year I will finish. In this first post, I wanted to document some mistakes which our schoolmaster committed when we wanted to avoid pupils approach Woknech on disk C: /. Perhaps he wanted to feel importantly (because no one objected, the teacher in case of PC useless to teach can turn off the fuse). However, that does it all began 😀😀😀😀
No I'm not annoyed. The second day was not even enter into the folder you have one on your desktop. Preventing Access explorer can be circumvented quite easily thanks TCMD.

I wanted to change the desktop wallpaper, which unfortunately did not go too classically change, so I found in the registry (which worked so far) parameter "wallpaper" and I changed the value (path) to the one I needed. Also, it occurred to me to look at the names of users who all server is stored. Not good for the professor ... probably he is so forgetful that he must write the password to the user description 😁😁😁😁😁
