This code will create menus for you to update Advanced Settings (or edit it to do other things… it’s the menus that are most important) for your ESXi hosts. It connects to vCenter, creates a menu of clusters to select from, creates a menu of hosts to select from and then executes the change. It puts the host in maintenance mode, updates the value and reboots the host.
The code runs past the edge of the page, but there are controls on the below widget to expand it so you can see all of it. 🙂
