Remove specific plugin from vCenter (use operation 'list' to figure out the key for plugin):

[vi-admin@scofield ~]]$ ./pluginExtensionManager.pl --server reflex.primp-industries.com --username primp --operation remove --key com.vmware.vSphereWebServicesSDK.primp-industries.com

Removing plugin key: "com.vmware.vSphereWebServicesSDK.primp-industries.com"

Alternatively, you can also remove any of the plugins by using the Manager Object Browser. You just need to point your web browser to your vCenter server:https://<your_vc_server>/mob

1. Click on content

2. Locate and click on ExtensionManager

3. Click on the plugin you're interested in removing

4. Record the plugin key id which is required to remove the plugin

5. Go back to the previous page and at the bottom click on the function UnregisterExtension, a new window will pop-up which will ask for the plugin key. Enter the key and then click on Invoke Method to remove the plugin.

6. You can refresh the page and you'll notice the plugin is no longer available and you can restart your vSphere Client to see the plugin has no been removed.
