SharePoint Feature Administration and Clean Up Tool

FeatureAdmin is a tool for SharePoint administrators and developers to manage SP features. It finds and cleans faulty FeatureDefinitions and orphaned reminders.

The Feature Admin Tool finds faulty FeatureDefinitions and cleanly uninstalls them.
It finds feature remainders in sites, SiteCollections, WebApps and in the Farm, caused e.g. by forcefully uninstalled Features from a farm without deactivating them before. These faulty features, never visible, cause errors.
The Feature Admin Tool is able to identify them and remove them.
Very useful for major version upgrades e.g. to 2010 or 2013, or for downgrades from Enterprise to Standard.

Also, uninstall, (bulk) deactivate or (bulk) activate features with any scope farm wide.
Ideal, for activating or deactivating features in large farms with many sites and/or SiteCollections.
