Configured Guest Operating System vs vmware tools reported OS

[d1avyt]

Hi everyone,

I am curious regarding the performance gain that you would get when you are matching the Configured Guest Operating System in the VM Options/General options with what VMware tools says that you're running.

We had many servers running Windows 2008R2/2012R2 that we upgraded to 2019 and we never updated the configured VM to match the new OS.

All the VMs are running fine but I was wondering if there is any gains, either on the Hosts or/and on the guest itself in term of performance?

Any thoughts on that?

Currently running ESXi 7.03i and Vcenter 7

Thanks in advance for your input.

Hi,

   It is always recommended to go with the latest VMware tools comes alone with the hypervisor.
Advantage of installing the VMware tool gives you the latest driver for the virtual hardware.

Which has enhanced feature to perform well with the guest OS.
