Connect to ad-hoc wireless automatically on restart

Today i want my computer to prepare ad-hoc connection every time starting windows vista. It's not a problem in windows XP but in Vista automatic connect for ad-hoc connection is not available. So, after google some solution i've found this:

netsh.exe wlan connect name=Profile2

where Profile2 is connection name.

Read solution 1: http://www.vistaheads.com/forums/microsoft-public-windows-vista-networking-sharing/124426-auto-connect-ad-hoc-wireless-network-vista.html

Solution 2: http://www.online-tech-tips.com/computer-tips/ad-hoc-networks-routing/

i've used solution 2 because it will start in 2 minutes after finishing loading all windows components. so the popup menu will appear in just second.
