Another solution is to use CoreSyncCustomHook.exe located at: C:Program FilesAdobeAdobe Creative CloudCoreSyncExtensioncustomhook. When you run the following command :
C:Program FilesAdobeAdobe Creative CloudCoreSyncExtensioncustomhookCoreSyncCustomHook.exe --uninstall="C:Program FilesAdobeAdobe Creative Cloud" --component="CoreSyncExtension"
Then all registration to the dll is removed from the registry, the dll will be renamed and placed in %TEMP% and with the next reboot the dll is removed from the machine.
