It is not recommended to use above registry key since it breaks the "zone elevation" security fix. Please use this tweak only if you have a valid reason to do so. The above is a per-user setting. |
In Windows XP Service Pack 2, no site from any Zone can open files in local machine zone, whereas in pre-SP2, only Internet Zone sites were restricted to open local files, while Trusted/Intranet can.

Disabling this restriction still breaks the "Zone Elevation" security fix. Use only for valid reasons.
Open Registry Editor and navigate to:
HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Lockdown_Zones\0
Backup the key to a REG file and in the right-pane, set the value 2101 to 0
