windows 8.1 amds and ipod services

Hello,

with the latest versions of Windows 8.1 and itunes 11.1.4 we encounter the following problem:

Using my account, the amds and ipod services are running, but the ipod does not show up in itunes.

With the account of my girlfriend (both local accounts on Windows 8.1) the services do not start (grayed out).

Thanks for any help in advance!

Best regards,

Uli
