This came up in the comments to one of my other posts, so I though Iâ€™d share.
Note: The Host Update Utility was depreciated with 4.1, so if you came here looking for thatâ€¦ my apologies.
The vSphere Host Update Utility, as far as I can tell is not actually offered as a separate download, but is rather bundled with the vSphere client and is a selectable option during installation. As admins most of us are trained to ignore these extra screens (after-all, who wants yet another Friendster toolbar installed?). This one is safe however, promise!
