Press the Windows key on your keyboard, type “Windows Features”, and press Enter. The Turn Windows features on or off dialog box appears.
Below are two different versions, windows 7 on the left and windows 10 on the right. On windows 7 select "Microsoft .NET Framework 3.5.1" and on windows 10 select ".NET Framework 3.5 (Includes .NET 2.0 and 3.0)
You don't need to select the child items for Windows Communication Foundation (WCF) HTTP Activation and Windows Communication Foundation (WCF) Non-HTTP Activation unless you're a developer or server administrator who requires this functionality.
Pending no additional windows related issues with the .NET framework windows should install the appropriate files once you hit the "OK" button and WMDC should open.
