My old version (that worked perfectly) just got disabled (yes, they admitted it) so they could force me to purchase an annual subscription (that used to be called extortion) - had no choice, at tax time. From reading this thread, I would concur that this is not a bug, but a feature.  The objective is to get everyone to store the company files online, for obvious (by now) reasons.  I have disabled all quickbooks executables from services.msc, scoured Task Scheduler (no entries), and have blocked all QB apps at the router. Seeking replacement product. Thanks to all who took the time to document your experiences.
