Tip: It can be advantageous to call php.exe (executable) to run scheduled tasks that execute html/php files instead of using the URL function.

Note: The benefits of using php.exe instead of URL: When you run script via URL it will occupy a PHP slot and moreover there is a time limit for maximal script execution duration. Running it using php.exe, you can specify another timeout, memory limits, etc.
