"There is, however, a key difference that it appears many Windows users don't get. In Windows, every program has its own installation routine. Usually, but not always, it requires you to click on some variety or the other of individualized setup program. In mainstream Linux distributions you use one program, often called a package manager, to install all your programs.
"Personally, I find the Linux method easier because not only do package managers install the programs, they also enable you to search for a program. Say you want a program to display Adobe PDF (Portable Document Format) files. In Windows, you need to find out what program you'll need-Adobe Acrobat Reader, then download it, and then install it. Easy enough, but it could be easier."
