Microsoft also offers a separate tool to create a bootable Windows 7 USB drive, which you can download from CodePlex. You can download the Windows 7 ISO from Microsoft’s software download site by providing a valid product key.

There is no official (legal) way except these two to get a Windows 7 ISO image. Otherwise, you will have to install Windows 7 using a DVD disc, which you can borrow from your friend if they have one. So getting Windows 7 ISO is not a problem if you are already a owner and just want the ISO for future installations. However, it will still let you download the ISO file separately, but only if you already own Windows 7 product key, not for testing purposes. So Microsoft doesn’t offer any easy to download or bootable USB creation tool for it.

Although, Windows 7 is the most used Windows version right now, but Microsoft’s focus is still on Windows 8 and 10 as the represent the future of Windows. Windows 7 is Microsoft’s most used Windows right now, so its quite obvious that many people still want to know how to create a bootable USB drive of it.

In this tutorial, we are going to show you how to get Windows 7, 8 and 10 ISO image (Legal and Free) and create a bootable USB drive out of it to install Windows in any PC (if supported). So it is important to know which tools you require and how to create a bootable Windows USB drive for your particular Windows version (7,8 or 10). The source to get the Windows ISO file is different and the tool required to create a bootable USB drive is also different (or at least the process is). However, the process and tools are actually different for the installation of each version of Windows.
