Creating batch files.

I'm pretty clueless at this sort of thing. Is there any place where I can find a ready made (or the text for a) batch file that will run an internet clean up for me? ie. delete cookies, temp internet files, history, url auto-complete (I wonder why? :rolleyes: ) , etc.

Also, I have two Yahoo account - one for my e-mail and one for a Geocities web url. How would I make a batch file that would delete one cookie and copy a replacement into the directory so I didn't have to enter a new username and p/w each time?

Cheers.
