How to enable .NET Framework 3.5 on Windows 8 without downloading

During the installation of some programs and drivers it shows  warning that .NET Framework 3.5 is needed. 

There is an easy way to install .NET 3.5 on Windows 8 without having to download the entire Framework from Microsoft.

You must have installation media for Windows 8 (could be a DVD or even a mounted .ISO with a Windows 8 installation) and make sure the media is for the correct version of Windows (32 bit or 64 bit). Copy the folder  "DVDdrive:\sources\sxs" to "C:\temp"

• Run a command prompt (cmd) as Administrator.

• Run the following command:

dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:C:\temp\sxs /LimitAccess

ENJOY....!!
