| Going on a bit of tangent (due to nostalgia) AUTOEXEC.BAT is a relic from the days of DOS. After the bootstrap calls the COMMAND.COM the AUTOEXEC.BAT gets called. It is like any other batch file, but you could instruct some basic setups that you want to do every time you switch on the PC.
MicroSoft kept this handy even when they shifted to Windows. Even when Windows has its own method for invoking tasks at start up, it can still be used. (I am not sure in Vista, what the case is). |
