This has been really helpful and convenient to many of us who would need to install or reinstall their operating system on their laptops and computers. It just has gotten way easier for us, without having to install it using the traditional CD drives or DVD drives.

Windows 10 has been the common go-to operating system as it has stood the test of time. You might notice that most laptops or computers comes with the default operating system which is Windows. If you have a look at your office’s computers, many businesses as well has the Windows operating system installed on their computers. I myself, from my childhood up to now, am using the Windows operating system and I think it’s just easier to stick with what you are used to.

It is pretty straight forward, as you just need to select the Windows 10 image file from your computer and the device which is the USB flash drive that we are going to use, and voila! You have your Windows 10 bootable USB flash drive.
