When you’re using Microsoft Windows 2008 R2 Core Edition, you only have an command prompt available within a console session. For some sysadmins it’s a no go. When you know what tools are available by default whitin the command prompt, it’s no big deal to manage some basic things through the command prompt.
For example, when you want to view all the available features in the Core Version, you can use the command:
dism /online /get-features /format:Table
dism /online /get-features /format:List
