first off its a joke
I knew that! my company has some strict rules on computing but we are allowed to change preferences such as resolution on the screen etc since we are the ones looking at the monitor.
As do many companies. However, one of the places I once worked installed lock down software. At least it was only on the machines of a very small group of test users.
The software had various settings that determined what the end user could change without needing the administrative password and key disk. Naturally our anal retentive IS group wanted "maximum security". This meant that the user could not access the control panel, the display properties, or even put stuff on the windows desktop. It was truely evil.
Fortunately sanity prevailed and the software was quickly removed. The outrage of the users as well as the help desk having to dispatch someone whenever a user wanted to make a change to their system both had something to do with the decision.
