Hi!
I have a problem with my product under Windows Vista Home Premium that can be reproduced with these steps.
Open Task Scheduler.
Start "Create Basic Task".
Create a task on "When the computer starts".
Open the newly created task's properties.
Click "Run whether user is logged on or not".
Click OK.
Being asked for the password, enter one. (The current user must have a password.)
Restart the computer.
Open Task Scheduler.
The "Last Run Result" column for the tasks shows 0x8007052E error code.
What gives
