DOS is not dead in these operating systems, but Microsoft does not make it accessible like their predecessors. From what I do know of these OS's, here are a few rather vague suggestions. Hopefully, you can apply them with your existing knowledge of your OS and how it handles bat files, and make it come together. Also, we have a great thread going on the subject here. A lot is covered here that I keep seeing in the same emails again and again.

Instead, these files are maintained on the sly by Windows Me for backwards compatible with apps that expect to find them there. But any changes you make to either file will be overwritten each time the system boots. However, I don't know anything about these, or if they actually will load on boot up. You may have to create a bat file that you run manually. 2000 does not have a deltree command, but it does have a rmdir command.
