For those who tired to press the cancel and select the open with list when they insert any CD/DVD and this popup comes everytime.
Here its solution to Permanently block this Autorun service:
Right Click on Mycomputer > select 'Manage' > select category 'Services and Applications' and Click 'Services' and check for the service named 'Shell Hardware Detection' then Right click on it and select its Properties and in Startup type option select Disable and Press Ok...Restart your system to take effect.
After you insert any Optical Media Windows does not Popup's and it directly opens Windows Explorer.
