We cannot install software on the computers at work. Only those with admin privilige can do so. This seems to be a very sensible solution. It is their computer and their choice about what software to install.
I know some think that it is harsh for the employer to restrict their computers but it is thier computer.
However, you would be amazed what you can run from a thumbdrive installation.
