Insufficient memory will cause errors as well. That's why software programs include minimum memory requirements. A program that needs 14MB of memory will generate errors on a computer that only has 4MB of memory if it runs at all. The same goes for disk space, monitor color depth and resolution.

Even though you may use Windows XP or Vista, batch files can save you tons of time by automatically starting multiple programs and performing different tasks at the single click of a button.
