As far as I know, and the documentation backs this up, an account is required for a scheduled task. If you set the task to run only when a user is logged in that only means a password is not necessary, you still need an account. This account can be set to a group so that the task will be run when it is triggered as long as anyone in the group is logged on. For instance you can set the account to 'Users' so that the task can run when anyone is logged on.

Answer 3

The GoogleUpdateTaskMachine Task uses the "NT AUTHORITY\SYSTEM" to Run the task. You can do this by using schtasks command and the /ru switch with "System" or "" as the parameter. Like this:

schtasks /create /tn "My App" /tr c:\apps\myapp.exe /sc monthly /d 15 /ru "System"

It does not prompt for a password.
