I had an issue with my IE 8, it kept crashing by just clicking on it to launch it, till the point I had to use Task Manager to kill the process.
I found Microsoft KB article 957700 to uninstall IE 8. So, I ran the following command:
dism /online /Disable-Feature /FeatureName:Internet-Explorer-Optional-amd64
Then you need to reboot your system. The previous KB only guide you on how to remove IE 8 and doesn't tell you how to re-install it.
Looking back at the previus command, I was intrigued by dism command and after searching the web I found an MSDN article that describes this tool.
To re-install IE8 back, I ran the following command:
dism /online /Enable-Feature /FeatureName:Internet-Explorer-Optional-amd64
Then rebooted the machine and got IE 8 installed again on the machine.
Now, the re-install did not do it for me I had to do the following steps to fix it in my scenario:
1. Launch IE 8 in safe mode: From the command prompt type the following:
2. Reset IE settings:
Tools > Internet Options: click on Advances tab and click on Reset button.
And that fixed the issue.

Note: The previous steps also applies to windows 7.
