@echo off
:::  Leave the "echo off" command on the first line!
:::  This causes Windows 9x to close a DOS window when finished


:::  NOTE:  If you run this batchfile exactly as it is, it will place some 
:::  harmless entries in your Registry and win.ini, then delete itself.

:::  This batchfile installs a value in any or all of 3 different locations
:::  in the Windows Registry, which will then cause Windows to run the
:::  specified application(s) at startup.
:::  It places comparable commands in either of two lines in the win.ini
:::  file with the same basic result.
:::  It shows no visible feedback to the user, aside from a DOS
:::  window that opens briefly then closes.

:::  All filenames and descriptions in this file are for example only.
:::  You'll want to change all instances of "infname.inf", 
:::  "Description of Your Choice" and "appname.ext" to whatever
:::  is appropriate, and of course delete the lines you don't need.

:::  I wrote this using several INF files as examples.  I also looked up
:::  Microsoft's page http://www.microsoft.com/hwdev/devdes/printerinf.htm
:::  to find out how the UpdateIniFields syntax works.
