As a developer, I found the new Internet Explorer version to be a complete nightmare. I turned the windows feature off, but I wasn't able to install Internet Explorer 10. It says that it's already installed which it is not. Is there a file or a registry entry I should delete as well?
Go to Control Panel -> Programs -> Programs and features
Go to Windows Features and disable Internet Explorer 11
Then click on Display installed updates
Search for Internet explorer
Right-click on Internet Explorer 11 -> Uninstall
Do the same with Internet Explorer 10
I think it will be okay.
