hmmmm no multi browser support. ok.
Actually the link works in any browser, but Firefox, Opera, Chrome, Safari, and all others render .reg and .bat files as plain text rather than treating them as a file download (in their default settings). In support, when trying to solve someone's problem, the path of least resistance is usually best. We don't want to have to start explaining how to right click on the link and select "Save link as.." or "Save page as" or whatever browser X calls it when someone just needs to get a file and get things working. We simply don't want to have to start supporting people through their browsers as well.
