A question came in about activating Nintex Forms 2010/2013 via PowerShell. It is fairly easy to do assuming you have the FeatureDefinitionID (0cdf436f-61b0-43d2-b250-4360f0353b63). Below you will find an example for how to activate/deactivate the feature via PowerShell.
Note: To deactivate the feature, uncomment the 5th line and comment the 3rd line.
