Microsoft Paul Trow specifically instructs users on how to install Windows 7 RTM:

The Windows 7 Interactive Settings Wizard provides users with three ways to install: Install only a net installation of Windows 7 single systems, upgrade the installation of Windows 7 from an existing system, and install a dual-system installation of Windows 7 while retaining the old system.
If you purchased a copy of Windows 7 DVD from a retailer or online, you can install Windows 7 by following the Microsoft New Interactive Setup Wizard (Interactive setup Wizard). 　　Before you start and run Windows 7, the Windows 7 Interactive Setup Wizard can guide users through the steps required to perform a series of needs. A clean installation is the preferred method for installing Windows 7 systems. Although users can upgrade from Windows Vista to Windows 7, there is a certain risk that this approach can cause some programs in the system to not function correctly. 　　In my experience, the best way is to completely upgrade to a new version of the operating system, especially an important version like Windows 7. The following screenshots are the instructions provided by the Microsoft Interactive Setup Wizard for the entire Windows 7 installation process. The Windows 7 Interactive Setup Wizard has a significant improvement over Windows Vista Wizard programs. 　　The Windows 7 Interactive Setup Wizard is simpler and faster than Windows XP.
