For those who are not happy with the IE9 Beta version(or for that matter any MS updates on your system) or have a issue/bug with the same can remove it from your WIN-7 with the following easy steps.
1.Go to the control panel and click on add/remove programs or go to run and hit “appwiz.cpl” and your list of programs pops on screen
2.Next you will find “View Installed Updates on your left hand side”.Click on it and you will find all the updates that you have made post your installation of the Windows 7.
3.Search through the updates (hint:it will be under Microsoft Windows separator) and click on uninstall to remove IE9 and you will be reverted to the default IE8.
**Note.You can also find the turn windows feature on/off on your left hand too.Use it sagaciously to install which ever feature turns you on/off!
