Create the Scheduled Task Item
Open up Task Scheduler through the start menu search box (usually you can just type task), and then on the right-hand side click the "Create Task" link:
The first thing you need to do is give the task a short, simple name, preferably without any spaces in it. Then check the box for "Run with highest privileges" (very important)
Now switch to the Actions tab, click the New button, and then browse down to the application that you are trying to start.
Create the Shortcut to Start the Task
Right-click anywhere on the desktop and choose New \ Shortcut from the menu schtasks /run /tn "TASKNAMEINQUOTES"
Now you can drag and drop (or copy/cut paste) the shortcut into the Startup Menu
