To remove a virtual machine template:
On the Templates tab, select the template you wish to remove. Click the Remove button.
The Remove Template(s) dialog displays, asking if you wish to remove the selected templates. Click OK to proceed or Cancel to abort the procedure.
Warning
If you have used a template to create a virtual machine, make sure that you do not delete the template as the virtual machine needs it to continue running.
