Thought I was bad, I'm using 2013 on an XP machine. I'm going to bite the bullet and replace my windows 7 machine with a 10 one of these days. I'll probably upgrade to the latest version of Quickbooks and put it on there mainly because I can't figure out how to port the old version over. Besides, I notice that they do fix some of the quirky things with each new version.I'm still using a 2007 version of Quickbooks. Runs fine on windows 10.
