I have been using my mac user id to login to parrallels, but today I decided to use my old microsoft login. didn't much care for it, but when i logged out, the original macintosh user id was not showing as a past user of the parrallels desktop login. i recall it had some sort of slash on the username, and probably the macintosh login ID, but what might have been on the other side of the slash, I would have no recollection. not concerned about the password, just trying to figure out the user i have always used. shouldn't it keep that information as an option for login? what is the proper default format for logging into windows using the mac id?
