I don't know how to solve the problem that the IE browser is locked to 2345 1125. cc cannot be modified. The browser is locked to 2345.com navigation or 1125. cc. Try to use the tool option of ie to modify the Main Plane and cannot be modified. Search for 1125.ccin the Registry directly and modify the startpage page. A message indicating an error occurred while modifying the page cannot be saved. Later, I found that the Registry permission was tampered. The solution is as follows: 1. open the following registry branch: HKEY_CURRENT_USER \ software \ micorosoft \ Internet explorer \ Main 2. right-click the Main branch, select permissions, and add full control permissions to everyone. 3. modify the startpage entry in the right window of the Registry Editor to be empty. 4. to avoid other program modifications, you can remove the full control permission of the everyone of the Main branch.
