Ok, I've seen a bazillion online complaints about this. Somewhere at Adobe something is broken. Repeatedly pushing out background services like Creative Cloud, Synchronization Manager, Genuine Check, etc. is at this point seemingly the same as pushing malware onto people's machines.
I'm sorry if this sounds heavy, but it's essentially the functional outcome, every single time. What I mean is that when my Windows machines, plural, slow down because of these apps. I only need kill Adobe processes to reduce my CPU usage by like 80%.
What could these apps possibly be doing that requires 80% of "any" CPU? Downloading updates? 80%, really? Browsers don't do this. I can't think of any other software that does this. Using Adobe > Preferences to disable these apps from running on startup seems to always have one net result, they run anyway.
I would really LOVE IT if Team Adobe would INVESTIGATE, IDENTIFY, and RESOLVE these matters in a lasting and meaningful way.
