- From the Objects tab, select an Update Manager instance.
The Objects tab also displays all the vCenter Server system to which an Update Manager instance is connected.
- Click the Manage tab.
- Click the ESXi Images tab.
- Under Imported ESXi Images, select the file you want to delete and click Delete.
- Click Yes to confirm the deletion.
The ESXi image is deleted and no longer available.
