After updating CC I see there's an update to Addictive Drums. Maybe in response to to re-authorization issue after the last Windows update?
Once installed, do not use the Command Center for Addictive Drums or Melodyne. Use the manufacturer supplied update routines. After install, it is best to hide them in the Command Center. Right-click on them to get the hide option. To speed up the update check, consider hiding DPro, Rapture and any thing else which is unlikely to be updated.
