This document provides the steps to perform a Clean Install of the Microsoft® Windows® 7 operating system on applicable VAIO® computer models which originally shipped with Windows 8. This process will take 1 - 2 hours to complete.

What is a Clean Install?

A Clean Install formats the hard drive before installing the operating system. All user data, files, and settings are erased and a new copy of the operating system is installed. A data backup (to an external drive or media, such as a flash drive or DVD) will be required to save desired files, such as documents, music and pictures. Existing software on your computer will also be lost and need to be reinstalled. A Clean Install is necessary when downgrading from Microsoft® Windows® 8 to the Windows 7 operating system.
