Q. How do I enable or disable a feature in the OS from the command line using the Deployment Image Servicing and Management (DISM) tool?

A. Windows 7 has all the files for features copied onto the system when the OS is installed. They're just enabled during the feature install process when they're needed, without any file copy operations from media being required. You can enable or disable features for your online OS or an offline-mounted image (WIM or VHD) using the /disable-feature and /enable-feature switches.

I'm going to disable Purble Place for my online OS. Tf it was an offline-mounted image, you'd would replace /online with /image:.

C:>dism /online /get-featureinfo /featurename:PurblePlace

To enable the feature instead, just replace /disable-feature with /enable-feature.
