Just want to share my experience after W10 november update (build 1511).
It uninstalled : HWMonitor, CPU-Z, CCCleaner and my USB drivers
As of today, I've not been able to get my front USB 3.0 ports play nice with my stuff. These ports now randomly disconnects.
I'm not really surprised about compatibility issues but the fact that it uninstalled software without my permission is very creepy and disturbing. I know that they have the "right" to do it, but still, it's a very weird feeling to hand over this level of control over to MS.
I'm very uncomfortable with this update and will definitely look for alternatives.
