AutoCAD Architecture :: How To Set A Font To Default

We just upgraded from '12 to '13, I am trying to find ways to set a font to default, but am unable to find a way that fits how we operate here.  My boss likes to do things a certain way, so I have to make sure whatever I do falls within his parameters.

Anyway: I have read a number of articles about people saying to just change your template settings and save it.  We don't, however, use a template.  I guess we could start (if he let me), but all we do now is copy another x-ref or architecture page or what-have-you, save it in a new file, and go from there. 

I also think I may have messed up my computer by trying to use fontalt.  Now every time I start my machine up, it asks me to specify the fontalt. How to turn that off?

But the main thing: is there a way to get a default font setting to affect all of our files at once?  If I go to "style" I can change every page at a time, but that gets lengthy.  Was assuming there should be one change that does everything.
