Hi ,
VMware Tools is a collection of drivers and utilities that admins install inside the guest operating system of every VM in order to optimize performance and manageability of workloads running on vSphere infrastructure. We regularly hear customers ask if there is a way to avoid rebooting VMs after executing VMware Tools updates. Although there is a technique that can be used to postpone restarting the guest OS, the reality is that when replacing certain critical drivers on Windows, especially for storage devices, a reboot is necessary for the update to take effect.
The VMware Tools engineering group has been working hard to reduce the reboot requirements through various means and have delivered a breakthrough recently that really improves the situation for VMs running Windows Server 2016.
Steps :
In the vSphere client, click VM in the virtual machine menu, then click Guest > Install/Upgrade VMware Tools and click OK. Choose Automatic Tools Upgrade for an unattended upgrade. After some time the VMware tools are updated the latest version without a reboot!
