The tool is available from the two locations below:
Here are the steps to use this tool…
That is the process – you are finished and you have a USB key ready to boot off of and install Windows 7. Compare it to the manual process I have listed below and you can see this is much easier to use the Windows 7 USB/DVD Download tool.

The 11 steps for manually preparing a USB Disk to be a bootable Win 7 Install.
1. Diskpart (Run from a CMD prompt)
2. List Disk
3. Select Disk # (Where # is the number of your USB disk)
4. Clean (removes any partitions on the USB disk, including any hidden sectors)
5. Create Partition Primary (Creates a new primary partition with default parameters)
6. Select Partition 1 (Focus on the newly created partition)
7. Active (Sets the selected partition to an active valid system partition state)
8. Format FS=NTFS (Formats the partition with the NTFS file system. This may take several minutes to complete, depending on the size of your USB key.)
9. Assign (Assigns the USB drive a drive letter)
11. Copy all the files from the Windows 7 DVD to the USB Stick.
