Symptom

When you open Internet Options and click the Advanced tab, none of the options may be displayed. This problem occurs if the following key (or some of it's subkeys) are deleted from the registry:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Internet Explorer \ AdvancedOptions


SOLUTION :

Click Start, Run and type this command

regsvr32 /n /i inetcpl.cpl

The missing options are now restored. This method works in Windows 9x systems as well.
