You need to design a recovery solution to ensure that you can restore the initial state of the locally installed LOB desktop applications if an application is misconfigured

You have 100 client computers that run Windows 8 Pro. Each computer has a single local
hard disk drive, a DVD drive, and an external USB drive.
Each computer has a different set of line-of-business (LOB) desktop applications that are
installed locally. All of the applications store their configurations in the
HKEY_Local_Machine\Software registry hive.
You need to design a recovery solution to ensure that you can restore the initial state of the
locally installed LOB desktop applications if an application is misconfigured. The solution
must preserve the existing locally stored user data.
What should you do?

A.
Enable File History. Restore files by using File History.

B.
Create a Microsoft Diagnostics and Recovery Toolset (DaRT) recovery image. Start the
computer from the DaRT image and perform a file restore.

C.
Run recimg.exe. Perform a system refresh.

D.
Create a system repair disk by using Windows 7 File Recovery. Start the computer from
the Windows 8 Enterprise installation media and perform an automatic repair,

Explanation:
Reinstalling all of your Desktop apps can be time consuming, so Windows 8 offers a
command called recimg.exe to make this easier. recimg creates an image which is used by
the refresh facility when restoring Windows. Not only will your personal data and Metro style
apps be saved, but so will Desktop apps you have installed at the time you create the image.
This can save you a lot of time.
