You are responsible for maintaining Windows workstation operating systems in your organization. Recently, an update from Microsoft was automatically installed on your workstations that caused an in-house application to stop working.
To keep this from happening again, you decide to test all updates on a virtual machine before allowing them to be installed on production workstations.
Currently, none of your testing virtual machines have a network connection. However, they need to be able to connect to the update servers at Microsoft to download and install updates.
