Windows7 And Windows Server 2008 R2 Not getting Booted in Normal Mode.

This will happen after the windows update is performed. To resolve this please follow the below steps.

Open your windows 7/Windows Server 2008 R2 in Safe Mode.
Now click on Control Panel.
In Control Panel click on Programs.
Now you will find Programs & Features.
Now you will find all the programs installed in your machine.
Filter the softwares based on Installed on date.
Now you see the software with Today date.
Select respective software and uninstall it.

Note:-
I think the name of the s/w would be Intel HD Accelerated Graphics Driver.
