As far as I’m aware it may have been early 12.x that this changed, but why you got 17,x installed with the settings still at manual is beyond my understanding of what was meant to have happened.

I’m not experiencing any instability on the one system (in my signature) that I have 17.2.2288 installed on. Though there are going to be may tens of thousands of system permutations and installed software running. On that XP system (and my others) I’m very tight on what I install and more so on what I allow to run in the background.
