Disable the Internet connection Wizard

Solution #1:
The next time it appears, click Cancel, and then select the Don’t show the Internet Connection Wizard next time option.
Note that disabling the wizard won’t remove the files from your hard disk (see Solution #2), which means it’s still taking up hard disk space.

Solution #2:
Delete the entire Connection Wizard folder (it’s in \Program Files\Internet Explorer).
Note that this won’t work in Windows Me – try to delete the folder, and it will just come back in a few seconds. This is caused by System File Protection – instructions for disabling SFP are in chapter 6 of Windows Me Annoyances, the book.

Solution #3 (if you’ve deleted it before disabling it):
Run the Registry Editor (REGEDIT.EXE).
Open HKEY_CURRENT_USER\ Software\ Microsoft\ Internet Connection Wizard.
Double-click the Completed value; if it’s not there, create it by selecting New and then DWORD Value from the Edit menu, and type Completed for the name of the new value. Double-click the new value when you’re done.
Enter 1 for the contents of this value, and click Ok when you’re done.
