Microsoft customers who download Windows 7 installation files through Microsoft Store, MSDN, TechNet, MAPS (Microsoft Partner Action Packs Subscription) Software on Demand Digital Distribution, or Volume License Service Center (VLSC), will get an ISO image file which is an archive file or disc image of an DVD optical disc.

Most people will choose to burn (or write) the Windows 7 ISO to DVD disc media to start the installation. Some people may also opt to make or create a bootable Windows 7 USB flash drive to install Windows 7 on PC systems that support booting up from a USB drive (changing of boot order or boot sequence in BIOS may be required), especially on computers (e.g. netbooks) that does not have a DVD drive. Furthermore, install operating system from USB hard drive or flash stick is also faster comparing to old-fashioned DVD.

To let customers have an easier way to burn and write the Windows 7 ISO image to a physical DVD media, USB flash drive (or USB stick), or external and portable USB hard disk drive, Microsoft Store has released a Windows 7 USB/DVD Download Tool (WUDT), which also known simply as ISO Tool published at Windows 7 USB/DVD Download tool allows users to create a copy of Windows 7 ISO file on a USB flash drive, USB hard disk or a DVD, by transferring the installation from the ISO image to the medium, and ensuring the DVD or USB drive is bootable. Been bootable mean the media allows users to install Windows 7 after starting up computer directly without having to first run an existing operating system on the machine.

Although burning an ISO to a DVD disc is easy, but converting Windows 7 ISO to a USB drive is much more complex, because ISO cannot be directly ‘burned’ or ‘wrote’ to USB drive. Copying all the content inside the ISO to USB drive also does not work, as the USB drive is not bootable. Hence, WUDT is very useful for Windows 7 users who want to port and transfer Windows 7 setup installation files to USB flash drive or external hard disk, which is also bootable.

    Tip: Do make sure that no important data is stored on the USB flash drive as it will be formatted (deleted).

  9. Once bootable USB device or DVD created successfully, user can install Windows 7 by navigating to the root of DVD or USB flash drive and double-clicking Setup.exe. It’s also possible to install Windows 7 directly from the USB key or DVD by booting from the USB key or DVD, where Windows 7 installer will be automatically launched.

    Windows 7 USB/DVD Download Tool (WUDT)

In order to copy Windows 7 setup files to a bootable USB key or USB flash drive, at least 4 GB of storage space capacity is required. WUDT runs on Windows XP, Windows Vista and Windows 7, and supports localized language versions of Windows 7, such as German, English, French, Italian, Simplified Chinese, Hebrew, Arab, Czech, Danish, Traditional Chinese, Norwegian, Japanese, Korean, Dutch and Spanish.

    I have tried many times to use it (physically in Germany) with a .iso of Windows 7 that I am pretty sure is in English. But everytime when I start the install everything is still in German (while I want it in English)

    I have made all the system locale, language etc to English right from the download of this program, then killing the internet connection before installing the program and making the usb, and the problem is still there.

    Any ideas?

    What is going on ?

  • Ryan

    This utility cannot use USB hard disk, it can only be used with USB flash drive!

    An alternative to this software is "a bootable USB", it can also only be used with USB flash drive though… (weird… why not USB hard disk?)

  • Geo

    Oh, shure it work installing an win7 from stick! Use Windows7-USB-DVD-tool program. It will take some time,so is good to be be patient. After that you need to tape fast F12 before loading windows. The screen will show 3 options. Choose the one witch say about USB. ALL the driver you need f. win 7/32bit you can finde at:

  • Cherimoya Eihn

    I have no boot menu on my laptop.
    And installation Windows 7 DVD was scratched.
    What i did was:
    1) download windows 7 installation ISO;
    2) unpack it on flash drive;
    3) boot from any installation CD/DVD (just to get close
    to command promt);
    4) format c:;
    5) copy contents of flash drive to c:;
    (xcopy f:*.* c:);
    6) reboot.
    The PC will boot from c: as it was some DVD and will actually install Windows on itself.

    Hey i got this error when I clicked "run".

    Installation of IMAPI v2 requires Service Pack 2 or higher.

    So does that mean I just need SP2 or higher or what?

    • Rusafie

      same problem 🙁 what to do?

  • Virtual World

    It will not work with Windows XP. Use WinToFlash instead.

    Remember to save your data from the USB pendrive.

  • hunt978

    Bro, can i apply this tool to create bootable usb flashdisk with other OS like XP, vista or linux? How bout burn any software still in iso image then usb can install them to computer? Does DVD/USB TOOL perform it? Thanks. . .

  • StuartB

    Does'nt work. I have a 160 Gig portable usb hard drive in perfect working order, empty and which is found by windows every time it's plugged in, whether it's my pc or anyone elses.

    I have tried this USB/DVD tool and it does'nt even find the drive.

    It says "No compatible USB Devices Detected"

    Funny how it's compatible with everything else I throw at it.

    It has booted up and installed Windows 7 previously without any problems. Since then it has been wiped and used just for storage. Any ideas for a fix would be welcome. Thanks.

  • Avijit_KG
