If you remove a template from the inventory, it is unregistered from the vCenter Server inventory, but it is not removed from the datastore.
You must be connected to vCenter Server to remove a template from the inventory. You cannot work with templates if you connect directly to an ESXi host.
- Right-click the template, and select Remove from Inventory.
- Click OK to confirm removing the template from the vCenter Server database.
The template is unregistered from the vCenter Server inventory.
