A. The DISM tool is a great way to manipulate offline images and online OSs. Using the command

                              dism /online /get-features                              

you can get a list of all the features that are available in the OS and their installation status. Your output will look like this:

                              Deployment Image Servicing and Management tool                              Version: 6.1.7600.16385                              Image Version: 6.1.7600.16385                              Features listing for package : Microsoft-Windows-Foundation-Package                              ~31bf3856ad36                              4e35~amd64~~6.1.7600.16385                              Feature Name : OEMHelpCustomization                              State : Disabled                              Feature Name : CorporationHelpCustomization                              State : Disabled                              Feature Name : BitLocker                              State : Enabled                              Feature Name : MicrosoftWindowsPowerShellISE                              State : Enabled
