About Patching Hosts with vSphere Host Update Utility
With vSphere Host Update Utility, you can download and install maintenance and patch releases, which
provide security, stability, and feature enhancements for ESXi 4.0 hosts.
You can use vSphere Host Update Utility to check for new release updates and patches that are applicable to
the ESXi hosts registered in the vSphere Host Update Utility. vSphere Host Update Utility builds the host list
by tracking the hosts that you connect to directly through the vSphere Client. You can also add hosts to the
list manually.
