Windows 7 USB/DVD Download Tool (WUDT) helps customers who have PCs without optical disk drives (such as small notebook PCs) to upgrade to Windows 7. (See http://www.microsoftstore.com/win7usb)
The WUDT is a free downloadable from Microsoft Store and the Microsoft Download Center. Windows 7 customers who purchase an electronic software distribution (ESD) edition of Windows from the Microsoft Store can create bootable USB devices (thumb drives or external hard drives) or DVD backup media by downloading the ESD edition (an ISO image) and then running the WUDT.
