The easiest way that I found was to just delete it's reference from your registry.

All the usual forewarnings apply; make sure you export the key before deleting it so you can restore it if needed or wanted, etc. etc.

• Press Windows Key + R to open the "Run" dialog
• Type in "Regedit" and press Enter
• Once RegEdit is open, navigate to the following key: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace
• There will probably be more than one "folder" (technically called 'keys', but since they look like folders, we'll just call them folders here); click into each one and look for the "Creative Cloud Files" key.
• Once you're positive that's the right key, delete it (the entire folder under the "Namespace" parent folder).
• Restart Explorer, and the "Creative Cloud Files" folder should now be CAPUT.
• Raise your hand high in the air and give Adobe the bird for making us have to go to this extreme manually, instead of simply adding an option in it's settings to turn it off.
