Hey chcooper, did you get a solution ?
I have a Sony VAIO SVF14N25CXB running Windows 10 (ver. 1511).
I have a similar error, in administrative events everytime I start the PC:
Task Scheduler service found a misconfiguration in the NT TASK\Sony Corporation\VAIO Care\DeployVAIOManual definition. Additional Data: Error Value: %ProgramData%\Sony Corporation\VAIO Care\VAIOUserGuideUpdate.exe.
How / where are those VAIO Care task configured ? The VAIOUserGuideUpdate.exe is nowhere to be found, so I just need to disable the faulty task.
