Easiest way to make a bootable Windows 7 USB Drive : techirsh

I would like to share the easiest method to make a bootable USB Drive for Windows 7, Windows XP and Windows 8 OS. I tried this method and it worked smoothly. I will say boot from USB is much better than booting from a CD or DVD just because this may reduce the installation time by 50% or even more.

Requirement:

.iso file of Windows 7 Boot Disk. (You can make use of applications like Nero to make an iso)
wintoflash Application, Download wintoflash
8GB USB Drive

Steps:

Extract the .iso file to a folder ( You can use winrar to extract .iso files)
Run wintoflash Application
Switch to Advanced Mode
In Task Drop down Box select Transfer Windows Vista/2008/7/8 setup to USB drive. Then Click Run Button
Now in Windows setup files path you have to Select the folder where you extracted the .iso file.
In Second box Select the USB Drive which you want to make bootable. (The USB Drive should be of 8GB or more)
Click the Run Button. You are done.

Safe Remove the USB Drive and insert it again to confirm that the process is completed successfully. You can see the USB Drive icon changed to Windows Setup icon.
