I went in the store the other day...
there were Laptops, and Desktops,
when I went on the laptop, I wanted to see how the keyboard felt, so i tried creating a new text file, it wont let you, you cant create a new folder or anything, they wont even let you open notepad. Or My Computer,
but then I went over to the desktop computers, and I could access everything, RegEdit, MSConfig, etc etc(RegEdit and MSConfig are accessed from the start -> run dialog)
why do they do this to the laptops?????

also,

most of the computers are running some crappy Best Buy program that you cant get out of, I tried Ctrl - Alt - Del 'ing it, but end task dialog would not even come up, then I tried Alt - Tab'ing out of it, I also tried hitting the windows key(to access the start menu), I cant get anything... do you think the store made a shell for windows, so you couldnt get anywhere?
or is it just a single program? if its just a single program, I would very much like to know how its made, because it is Very secure.
