For starters, if you're not sure what a program does, search
the web to get a quick overview before you delete it. Some programs don't allow
you to uninstall them. For those that do, on a PC go to the Start menu >
select Control Panel > select Add or Remove Programs. You'll be supplied
with a list of all the programs you can safely remove from your computer in one
click. On a Mac, you can simply drag and drop the program folder into the
trash.
