| VMware ESX 4.0 and vCenter Server 4.0 Edition |
Before you can uninstall an update or patch from an ESX/ESXi host from the command line, you must have access to a machine on which you can run the VMware vSphere Command-Line Interface (vSphere CLI). You can install the vSphere CLI on your Microsoft Windows or Linux system or import the VMware vSphere Management Assistant (vMA) virtual appliance onto your ESX/ESXi host. For information about deploying or installing the vSphere CLI, see the VMware vSphere Command-Line Interface Installation and Reference Guide.vihostupdate.pl --server <server> --queryvihostupdate can remove only one bulletin at a time.
