Using Windows 10 64-bit Version 10.0.17134 Build 17134 and CCleaner Pro v5.52.6967. I noticed a new program, AppleMobileDeviceProcess.exe, running after a reboot and could not determine what was starting it. I didn't see anything new in CCleaner's startup list, so I looked in the Windows Task Manager's startup tab where I saw a new entry "iTunes Mobile Device Helper". It runs under the Windows explorer. This may have something to do with iTunes being changed to a Windows Store app.
I should also mention that "iTunes Helper," which used to appear on CCleaner's startup list, no longer does, but does show up in the startup tab of the Windows Task Manager.
