Extra programs and files pop up Connected to Creative Cloud

Hello!

I have Creatiev Cloud installed as well as Illustrator, InDesign and Photoshop. I have experienced that a lot of different Adobe and Creative Cloud applications pop up such as CC Troubleshooter, Core Synch, AdobeIPCBroker, Adobe Creative Cloud Diagnostics, Creative Cloud Account Manager, Adobe GCClient, and AdobeCleanUpUtility. As well as things connected to Illustrator like "Web Gallery", "Make CCCalendar" and "Contact Sheet".

I wonder If all these actually serve a purpose? Together they take up a good amount of diskspace.
