Restrict Web Sites from Installing Software for Internet Explorer

Restrict Web Sites from Installing Software (All Windows)

These restrictions allow you to block unwanted web sites from downloading software onto your system. This can be useful in disabling the installation of some common "cursor" programs.



Open your registry and find the key below.



Create a new sub-key for each site you want to block, naming it based on the top-level domain for the site. For example to block www.restricted.com you would create a new sub-key called:



[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\restricted.com]



Under the sub-key create a new DWORD value called "*" and set it to equal "4".



Restart Internet Explorer for the change to take effect.



Note: This setting can also be applied on a user-by-user basis by modifing the same key under the HKEY_CURRENT_USER hive.
