I'm a control freak. So I need to know - how can I have more control over my computer? I want to place restrictions on what users can do on the computer. For example, is it possible to make certain programs inaccessible without an override password? The only reason I ask is because once I was on a school computer and tried to load Windows Explorer to fix a problem and the computer wouldn't let me. How can I do things like that? ______ Entirely unrelated question - sorry - but it didn't deserve its own thread. Are computer companies purposely screwing me over when they claim that 1GB=1 billion bytes? I thought 1GB=230bytes!
