Richard, you are logging in to your registered web based copy of system 
access.  When you reboot the computer, system access disappears with out a 
trace.  You log in to download the program and get it running.  In the dos 
days this was called a "tsr" terminate and stay resident" program.
It lives in memory, nothing is saved on the hard drive.
I have no idea about the computer being registered question.  When you run 
window-eyes or jfw from a thumb drive, when you are done, a video intercept 
little piece of software is left behind.  I am very uncomfortable with this.
