In this article, I’ll show you how to check a VMware ESXi Host Version and build number using the all-new Sphere Web Client.
With the release of ESXi 6.5 the Windows “Fat Client” Is no longer available and all administration Is now done using the Web Interface.
Note: If you don’t have the Web Client and you are using ESXi 5, 5.5 or 6, you can use the Windows “Fat Client” to check the version using the following article: How To Check VMware ESX or ESXi Version and Build Number
