This is an excellent suggestion and one that I would recommend to all Quickbooks Desktop users. It means that you're stuck with the annoying login popup every so often, but it prevents Intuit from further messing with your software. If, like me, you want to disable automatic updates after doing this and before rebooting you can open taskmanager click on the task names column, scroll down to where you'll find 2 tasks starting with "QB..." and just end those.
