Disabling pop up window

[gpsman]

I know this has probley been covered before but I can't seem to find it in the search area.  How do I disable that pop up window that says " Extended Warranty" giving you the three options to choose from. I have an extended warranty already and have selected the "not interested" and also the I already have one, button. It just keeps coming back HELP............

Remove an automatic action from Task Scheduler

To prevent automated tasks from starting multiple times, remove the entry from the Task Scheduler by performing the following actions:

Click Start , type Scheduler in the search field, and select Task Scheduler when it appears.
If prompted for permission, click Continue .
In the left column, click Task Scheduler Library .
In the center column, select the task you want to stop. (HP Extented warranty)
In the right column, click Delete , and then click Yes to confirm deletion.
Close the Task Scheduler window.

The task or reminder will no longer begin automatically.
