Close Pop Up Window at Log In

Hi everybody

I've just started to use KM. Maybe you can help me with a following issue. I use a Canon printer and everytime I log in I see a following messagebox:

It's caused by Canon CAPT BackGrounder - a printer's background application. I want KM to click automatically on Deny. I managed to make a following macros and want to know if its the best way to do it.

Thank You for Your help!
