Thanks for answer.
The article ask to install SP1 to solve the problem.

I hear you, but did you try method 2?

Similar to:

Running Scheduled Tasks without a password:

For Pro: Start/Control Panel/Administrative Tools/Local Security
Policy/Local Policies/Security options. In the right hand pane (third down).

Accounts: Limit local account use of blank passwords to console logon only.
This is enabled by default, disable it.

For Home: Run Scheduled Task without a Password (Line 68)
