Channel 10 - Microsoft's Official USB/DVD Download Tool Helps you Upgrade Netbooks to Windows
I haven’t tried this yet, but I’m pretty happy to see it up there. The help file is available on the Microsoft Store site here.
One of the best new products in Microsoft’s newly revamped online store (store.microsoft.com) is the USB/DVD Download Tool. When you purchase a copy of Windows 7 from the store, you have the option to download an ISO file. With this tool, you can create a copy of that ISO file on a USB flash drive or DVD.
