Hi. Just purchased a pc. It came with ie8 installed and I updated to ie9. But a site I frequent (and which uses java virtual machine) is crashing my system. I uninstalled and reinstalled java. I uninstalled ie 9. I want to uninstall ie8 and revert to 7. But when I click "view updates" internet explorer 8 is not listed. It is also not listed as a program. How do I revert to ie7 in windows 7?
