Why do I need an account to stop creative cloud from starting itself?!

So my boss used my workstation one day, and felt the need to install Creative Cloud Desktop.

I However, have no need for this software at all. So I wanted to disable it from starting automatically and eating up computer resources every day. Not only is it completely impossible to stop the program from starting itself on windows using normal Task Manager settings, you can't even close the application by right clicking it in the task bar! Absolutely crap design choices here.

But to add even more insult to injury, I've been forced to make this account to even have the possibility of turning it off! What a scam this is. Every single developer that worked on this should be ashamed of themselves.

P.S.: Why are the only topics I can chose from 'File Sync' 'Collaboration' 'Libraries' and  'Cloud storage web assets'. There should be a 'bugs' or 'feature request' section if you guys want to actually provide a modicum of customer service. That is also the reason why the topic for this post makes little to no sense.
