The change started to come over the SK Telecom's corporate culture. The company distributed desktops with Windows 7 and Office 2010 installed for users. This path for upgrade is not different from any other companies. However, SK Telecom differentiated it from others! That is, SK Telecom initiated another challenge called desktop virtualization in the second half of 2011. It started the desktop enhancement, because it thought that not only improving business convenience. It selected Windows 7 and Office 2010 as a virtual machine-based standard business environment to provide consistent user experience to users regardless of devices they use such as notebook, tablet, PC, etc. and allow them to work productively.
