I installed IE7 RC1 and basically I couldn't access any webpage. I used the connection diagnostic tool and it says many of my connections failed. However, other browsers work fine for me like this one. With this IE error I couldn't even use many of the download managers like the one for installing IE6 (it says connection failed or so). I'm very troubled and hope to reverse back to IE6. But when I uninstall IE7 RC1 from control panel, even though it seems that it was uninstalled, my IE7 still remains there. I tried many ways, even like trying to install a standalone IE and downloaded Microsoft's IE6SP2 registry, but still has the same problem. Is there any way I could revert back to like when I freshly installed Windows? Thanks a lot.
