Patching a Standalone ESXi host using the shell
Overview As with any system running software, you are going to have to apply patches to it at some point and VMware is no different. VMware recommends customers install all security patches to maximize the protection that VMware provides. For a list of all security patches, you can go here https://my.vmware.com/group/vmware/patch#search. Login with your myvmware credentials.
Once it has been determined patches are available for ESXi, download the offline bundle so they can be pushed out to each VMware host as needed.
