Depending on what you're original version of Internet Explorer was, Uninstalling Internet Explorer 10 in windows 7 will revert the browser back to either IE 8 or 9.
If you're for some reason having problems with IE10, then this is one way of going back to a different browser. It's not suggested (and I'm not suggesting it). I'm just posting it because I have friends who ask me how I can do this. Also, there are better tutorials out there on youtube, so feel free to pick the more popular ones with more hits. I just made this for myself. Thanks.
Internet Explorer is slightly different from Normal programs in that you have to uninstall it using one extra step. At the top left of "Programs and Features" just click on "installed updates" and then try to find the entry for Internet Explorer. That's it. Nothing complicated.
