Hello schiba,

No it is NOT possible with KiXtart or any other application that is not attempting to circumvent the built-in security of NT.

As an Administrator you can remotely install applications via Task Scheduler or WMI remote execute. But a normal user will not be able to logon and install software.

You could install some MSI with Active Directory that will install with Admin rights, but not under the credentials of a normal user without modifications to the registry.
