Remove IE9 and reinstall IE8 on Windows 7

Question

Hi Guys,
We have an issue were we have some Windows 7 running on it. We need to access an old System that doesn't support IE9 or any other bowser except IE8, IE7 or even IE6. Is there a way to uninstall IE9 or even install IE8 Along side IE9?

Answer 1

Niki Han is incorrect in his statement, “if Internet Explorer 9 is pre-installed on Windows 7, it cannot be uninstalled”.
The closer to the correct answer is the one from Little Sheep, “IE8 is a built-in feature in Windows 7. You can turn it on or off from Windows Features.”.
Wayniak… Follow these steps:
Go to
Start, Control Panel,
Programs
Click on
View installed updates under Programs and Features section
Scroll down the list in the Microsoft Windows section and find
Windows Internet Explorer 9
Select this item and click on
Uninstall
When prompted to confirm click on
Yes
Restart your computer
OEM installs of Windows 7 Pro I have seen have some with both IE 8 and IE9. 
In both cases, the OEM install usually comes with updates, hot fixes, service packs, etc. installed just like you and me would do in their factory image. 
They are in a little bit different place… but they are there! 
You will have to run setup wizard for IE 8 when you openthe browser back up the first time. 
And I did have to do this twice on one machine but it did work successfully the second time around.
You do have to remember now, when you run Windows Updates the next time, to make sure you mark the update
Click on
Tools on the menu bar and select Windows Update
(You may have to activate the menu bar or type Windows Update from the Start button)
Click on
Check for updates on the left
When updates are ready click on 
the XX important updates are available in the center of the screen
Uncheck
Windows Internet Explorer 9 for Windows 7
Right click on
Windows Internet Explorer 9 for Windows 7 and select Hide update
Click on
OK
That should do the trick! 
This has worked perfectly for me each time I have come across the issue. 
Good luck!!
