Go to the address https://msdn.microsoft.com/en-us/windows/desktop/bg162891.aspx and download the SDK installer.
After download start sdksetup
Note the default installation path and click Next:

You can copy the files from the virtual machine to use it on another computers, and after copying the files off the VM you can dispose the Virtual machine.
