    Before removing IE8 due to compatibility in viewing some websites, consider enabling Compatibility View in Internet Explorer. If the reason you want to remove IE8 is because of compatibility issues with programs & add-ons, check the program vendor’s website for any updates or fixes to support IE8. You should also note the following prior removing IE8:

    • IE8 is part of Windows 7, disabling or removing access to IE8 means you will not have a browser anymore. Make sure to download or install an alternative browser before removing IE8. If IE8 has been removed, you will need another computer to download your new browser or any software installer that is bundled to install or download another browser. Example: Avast anti-virus and Ad-Aware anti-malware is offering Google Chrome browser free.
    • Removing IE8 in Vista and earlier operating systems means you are reverting back to the prior version – IE7 or IE6.
