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.

To change this, follow the next steps:

1. Open the Registry Editor click on the Start button on your taskbar, then click on Run and type "regedit" and click on OK to start the regedit utility.
    
2. 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 (see picture 1).

3. Under the sub-key create a new DWORD value called "*" and set it to equal "4".
    
4. Then create a new sub-key called HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion \Policies\Explorer\DisallowRun and define the applications the are to be restricted.
    
5. Creating a new string value for each application, named as consecutive numbers, and setting the value to the filename to be restriced (e.g. "regedit.exe").
   
   
6. The modifications you made will be in effect after you restart the Internet Explorer.
