Hi, when using unatteneded access, the username required doesn't change when the actual user of the PC has renamed it. Even if unattended is set up with the current ( but different to the original ) username, we still require the original. If there something you can do about this as it involves going to a command prompt or similar to check the actual name. It has always been this way.
Also on Winows 10 if a user has a microsoft account, it is unlikely we'll be given that password for unattended access, any way around this e.g. using PIN entry ?
