Determine zone setting and restriction in Internet Explorer (IE) through programming
The Zone settings are saved in the registry. You can write a local program to read/write the settings from registry. The same can also be done via javascript; but for that the IE security settings should be low enough to allow you the same.
Following is the key, where setting for specific zone is saved.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\
Where is defined as
Value Setting
------------------------------
0 My Computer
1 Local Intranet Zone
2 Trusted sites Zone
3 Internet Zone
4 Restricted Sites Zone
-------------------------------
If you wish to determine, whether a particular setting is enabled or not in a zone; then you can look for the value for the following keys in the respective zone section:
