How to roll back from internet explorer 8 to 7

I updated to Internet explorer 8 and it caused some big  problems on my computer system  and i can't access some of the sites.And if you have a save file of your old windows internet explorer so it is good for you and if you don't have so you haveto use a cd of it.

Here are the steps I did to roll back to my old internet explorer 7 :

Open up your Control Panel

step-1:Click on "Programs and Features" (may be called "Add/Remove programs" if you are using an older version of Windows)

Step-2:Click on "View Installed Updates" in the left pane

Step-3:Right-click on "Windows Internet Explorer 9"

Step-4:Select "Uninstall"

Restart your computer when prompted and then it will boot back up and it will be working your old windows internet explorer8.

If u have another any internet explorer(6 , 7 , 8 , 9 ,10)u just have to follow same steps if u get some problem leave a comment........
