When I try to open a html file on my local c: drive, IE8 ask for the trusted site security. I try to add this file as a trusted site but I am unable to do so. Can you help me?

Hi, thank you for posting here. There are two test you can try: Test 1: 1. Open the Control Panel 2. Open Internet Options 3. Click the Security Tab 4. Click on Local Intranet 5. Click on Sties 6. Click Advanced 7. Type 127.0.0.1 in the “Add this website to this zone” box. 8. Click Add 9. Click Close 10. Click OK 11. Close Internet Options by clicking OK 12. Close the Control Panel Test 2: Create a new string value at: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Interne t Explorer\AboutURLs" and set the value to point to a local HTML file. Next go to the Internet Options Security tab and go into the trusted sites menu. Now add "about:stringname" without the quotes (where 'stringname' is the name of the registry value you entered). Note: You’d better backup your registry before you want to change it.
