Good to know, I'll just stick with my older install media, lol.
oh, it probably did and possibly. you should enter the key next time and see what happens. you may be triggering it by not using a key so it wants you to go online to try and find a key or sell you one.
Of course the media used or the method of media creation as well as whether a key is entered is irrelevant, as the account creation portion of the Windows installer is called the OOBE and is cloud based - So chances are you're not going to have the option to create a local account if you're connected to the internet during install no matter what you do.
