Something that I have always had to work with, and always found a work-around for, was getting my downloaded .ISO file of Windows 7 or Windows Server 2008 R2 onto a USB key and use that as the installation source.
Well, this new tool is going to make that process much more simple.
Introducing the Windows 7 USB/DVD Download Tool.
From the link above:
The ISO file contains all the Windows 7 installation files combined into a single uncompressed file. When you download the ISO file, you need to copy it to some medium in order to install Windows 7. This tool allows you to create a copy of the ISO file to a USB flash drive or a DVD. To install Windows 7 from your USB flash drive or DVD, all you need to do is insert the USB flash drive into your USB port or insert your DVD into your DVD drive and run Setup.exe from the root folder on the drive.
