Have a Windows 8.1 system with IE11. When you open any page using IE11 you get only a blank page with no URL in the address line. When you type a good URL in the address line you still only get a blank page. There are no error message or other indications of this problem. Have scanned the system with Malwarebyte several times to remove malware and have also used ESET to remove any virus infections. Cleaned up the file and registry systems with Ccleaner but still IE11 refuses to display any web page. When we try to open the TOOLS option in IE11 nearly all options are grayed out and not accessible. We have reset/restored the IE11 options through Control Panel/Internet Options/Advanced without any change. Since it doesn't appear to be possible to downgrade to IE10 and IE11 won't reload because it already exists does anybody have any suggestions?
