How to validate the installed version

To verify the current version installed in your Windows virtual machines, do a right-click on the VMware tools icon in the system tray and select “About VMware Tools”. The installed version will be displayed.


This article describes the steps to update existing virtual machines with the latest VMware tools. It assumes that the Performance Cloud VMware organization and virtual machines are already up and running.


You must run the latest version of VMware Tools or use the “open-vm-tools” command distributed with the Linux OS distribution. Although a guest operating system can run without VMware Tools, you must always run the latest version of VMware Tools in your guest operating systems to access the latest features and updates.


It is also possible to contact our Cloud Support team so we can enable the feature named “Check and upgrade VMware Tools before each power on” in the back end on each desired virtual machine(s). The next time the virtual machine is powered on, it checks the host for a newer version of VMware Tools. If one is available, it is installed, and the guest operating system is restarted (if required).

However, please be aware that in requesting the VMware tools auto-upgrade feature, Sherweb will not be responsible if the automatic upgrade fails and/or causes functionality issues to the virtual machines for which this feature is enabled. 

For Linux or other Guest operating system, please refer to the VMware documentation: https://kb.vmware.com/s/article/1014294
