SharePoint 2013 Pre requisites install fail, Error: The tool was unable to install Application Server Role, Web Server (IIS) Role.

While installing SharePoint 2013 in a Windows 2012 Server I was getting the following error right after the prerequisites installation begins:

SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired
Error: The tool was unable to install Application Server Role, Web Server (IIS) Role.

To solve the issue I set the following Local Policy:

1. – Windows Start

2. – run MMC

3. – Click File, Add/Remove Snap-in…

4. – Select Group Policy Object Editor and ADD it

5. – Navigate to Administrative templates / System

6. – Select and edit “Specify Settings for optional component installation and component repair”

7. – Enable and select “Contract Windows Update directly to download repair content instead of Windows Server Update Services (WSUS)”

9.- Re run the prerequisite installation
