How to uninstall Internet Explorer 9

Some users may have installed the beta of IE9 to just to have a sneak peak of it and want to go back to a previous version of Internet Explorer after testing the beta release on their computer.

The answer to that question was yes: Internet Explorer 9 replaces an older version of Internet Explorer during installation. So you need to uninstall IE9 to go back to stable version of Internet Explorer.
Unlike most other programs on your computer, however, you won't find IE9 listed on the Uninstall or change a program screen. Windows Internet Explorer 9 has been installed as a system update in the operating system.

Here's what you need to do to uninstall IE9 on Windows Vista or Windows 7:

Click Win+R and type appwiz.cpl. click your windows button and type view updates in the search box

Once the results appear, click view installed updates

Don't want to search? Press Win+R and paste in the following:
C:\Windows\explorer.exe shell:::{d450a8a1-9568-45c7-9c0e-b4f9fb4537bd}
then press Enter.

Wait for the Uninstall an update screen to load completely

Scroll through the list until you find Windows Internet Explorer 9 (see fig below)

Click once to highlight IE9, then click the uninstall button (or right-click and uninstall)

Confirm that you want to uninstall (click yes)

Click one of the following:
