"Broadband connection with required username and password" When the computer creates a broadband connection what about the gray?

Open the registry first, we "start"-"run" then in the pop-up box type "regedit" and then back to the headlights

1, delete

Hkey_current_user\\software\\microsoft\\windows\\currentversion\\telephony\\cards\\nextid, reboot the computer and see if the problem is solved.

2, delete

Hkey_current_user\\software\\microsoft\\windows\\currentversion\\telephony, restart the computer to solve the problem.

Registry deletion be careful to see clearly oh, do not accidentally delete other things cause other functions can not be used properly.
