Everything used to be done at the command line. "Windows busted out the crib." Out the box there are rules and conventions to which the Normal people must abide. Windows is very customizable. I can remember the computer command line was an amazing place where if you knew what to type you could make it do most anything. You can still write your own .com file from the CMD or create any file just type 'copy con testfile.txt' then type what you want then CTRL-Z and poof you made a file. There are so many programs running now on a pc that seems to be doing nothing but they are all like alligators laying around for something to step into the pool. Click a link on a web page and you might download install and run a base36 string of characters if your antivirus or settings do not protect you. When you power up a PC your no longer alone but subject to the will of anyone in the world who managed to contribute.
