This actually easy encrypt there network connection and there credentials Cardspace, and then change to chinese or langauge that can't be translated easy and then when it shows up they will be checking langauge setting to see what the " heck" just happened,
But to undo this is not that easy.
The secondary thing about Admin is not to do this to admin less you know language and then french 1 which is first way french was spoken and if they can't since they don't teach french one here, it comes up incorrect, but to undo just un encrypt the language in Encryption but it's a prevenative if you don't have security program or antivirus which most people only know one or 3 languages.
In experimenting with computers if you have a travel computer often this was done on business laps is to use language they speak and then second language learn it would be encrypted to so lets say spainish verses french, normal is spainish and the encryption override on computer library of terms would be reset to another langauge as french, thus if they don't know how to speak the langauge then they can't read what your typeing do's require a change in keyboard language perfernces from spainish to english and sometimes hacker will go after the keyboard mod program to mess ya up, in computer, some will change what you did to Arabic to Norweign language to make ya made so make sure if you do it's complex.
I shouldn't be so bad but if you want to trick up a credental already in use,
Add credential and then add import ADM creditail, what happen is they will think there doing a credential swap were it request the rest of there credentials and setting, believe it or not nasty trick, but if you behave your self on secondary account you can see everything that person doing, and even down load the program off there computer when there not there,
Far as snag and run i wouldn't advise it cause it will show in history log were it got sent too.
But in the fact of things they can if not done write encrypt you out of your own OS, and then you get into trouble or they may add your admin to there computer of Quota's and then secondary your system.
Anyway just a thought for people who are nosey.
