when you uninstall ie9, the system reverts to ie8 without updates, first update ie8, then go back into installed updates and find a kb update with no description and uninstall it, then install ie9, it worked for me, after ie9 installs and you reboot, you will need to reinstall adobe flash ... to clear out the clutter, the mrus, activeX and such i use ccleaner, wise registry cleaner, and wise disk cleaner. i just uninstalled ie9 and reinstalled it yesterday to make it new again
