The list of websites which are added to various security zones in Internet Explorer is stored in one the following registry keys, depending upon the security configuration in the system:
HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Internet Settings \ ZoneMap \ Domains
HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Internet Settings \ ZoneMap \ Domains
When a domain is added to a security zone in Internet Explorer, a key is added to the Domains key in the registry. Subdomains appear as keys under the domain where they belong. Each key that lists a domain contains a DWORD with a value name of the affected protocol. The value of the DWORD is the same as the numeric value of the security zone where the domain is added.
ExportZone utility - Description
Because the Trusted, Intranet and Restricted sites listings are stored under the same registry key (Zonemap\Domains), it is a difficult task to export the list of sites pertaining to one particular zone (for example, Trusted sites). For this reason, I wrote the ExportZone utility, which can export the Trusted and Restricted sites listings to separate .REG (Registration entries) files.
NOTE: This utility assumes that the policy Security Zones: Use only machine settings (Security_HKLM_Only) is not enabled, and therefore it gets the domains list from the HKEY_CURRENT_USER part only. In other words, if the Security_HKLM_Only policy is enabled, this utility does not help. Future versions of this utility may include a check to determine if the Security_HKLM_Only policy is enabled, and if so, get the data from HKEY_LOCAL_MACHINE area.

This utility was originally written and tested under Windows XP Operating System only. I believe ExportZone is pretty straight-forward and needs no detailed instructions on its usage. If you need more help, contact me via this feedback form and I'd be happy to do a write-up for you.
