Okay, so the wife's yoga is on 8.1, but my laptop is still on 8. I made a mistake when I upgraded hers in that I didn't know about the local account workaround on the update screen. Happily, it reinstalled her apps.. (happily for me that is) Anyway, I use local accounts on all my computers. My laptop local account is not an administrator, so my question is, will the computer recognise that there is an administrator on the computer, plus a local user account when I 'upgrade' to 8.1? All I can find on the MS website is information inferring it was on a single user computer. Thanks for any help you can offer... Andy P.S. I'm not allowed to have an MS login account or use Skydrive.
