Use Windows installation media
You can use the Windows installation media as the file source when you enable the .NET Framework 3.5 feature. To do this, follow these steps:
- Insert the Windows installation media.
- At an elevated command prompt, run the following command:
Dism /online /enable-feature /featurename:NetFx3 /All /Source:<drive>:\sources\sxs /LimitAccessNote In this command, <drive> is a placeholder for the drive letter for the DVD drive or for the Windows 8 installation media. For example, you run the following command:Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess
