How to Install VMware Tools in CentOS 6.4

VMware Tools is an optional, free set of drivers and utilities that enhances both the performance of a virtual machine’s guest operating system and interaction between the guest and the host. From time to time I find clients have not installed the VMware tools in their virtual machine’s (VM) operating system. Although the guest operating system can run without VMware Tools, you lose important functionality and convenience. Related Video: https://www.youtube.com/watch?v=pO7iZbuTYJU

What is CentOS? CentOS, which stands for the Community Enterprise Operating System, is a distribution of the Linux operating system based on Red Hat Enterprise Linux (RHEL).
