If you are trying to install .NET Framework 3.5 from the  Server Manager  GUI, you will see this when installing the feature: “Do you want to specify an alternate source path? One or more installation selections are missing source files…” To solve this, you can either: 1.

By default a Windows Server 2012 Hyper-V virtual machine is configured to automatically save the state of the virtual machines when the physical computer is turned off without shutting down the guest operating systems. With this configuration, if the corresponding service was running during the shutting down of the physical computer, the virtual machines automatically boot up from the saved state after the physical computer powers on again. With this kind of default configuration, the overall boot time of the physical Windows Server 2012 becomes quite slow. In order to use the virtual machines efficiently, you can configure the Hyper-V VMs to automatically shut down before the physical computer is finally shut down. Here is how you can configure the Windows Server 2012 Hyper-V virtual machine settings in order to get the optimum results: Using the appropriate account that has the required privileges, log on to the Windows Server 2012 computer on which the Hyper-V r
