A clean installation and upgrade of Windows® 7
What is the difference between a clean installation and an upgrade of Windows 7?
A clean installation or what Microsoft calls a custom installation is when we boot our PC with Windows 7 Setup media which is typically a setup DVD, but with this version it can also be a specially created, bootable USB memory device containing the setup bits with the intention of just installing Windows 7 on the PC. If there was a previous version of Windows XP or Windows Vista installed on the PC already, you can either install Windows 7 to a separate partition or can wipe out the previous Windows version during the setup. If it is the latter, ensure that backing up of all the data is done first. The upgrading installation normally does not require any backing up of data and these data are automatically getting stored safely in the new operating system.

It is important to backup all necessary data in a clean installation while it is not required in the upgrade installation.
