How to create a copy of Windows software

Today, CDs (compact disc) and DVDs (digital versatile disc) are used far less due to faster and smaller storage media with more significant capacities, like USB (universal serial bus) flash drives. Consequently, many users don't have (or never had) a Windows installation disc. However, it's possible to create an ISO image file and load it on a USB drive or DVD-R (digital versatile disc recordable) using the steps below.

After doing so, use the disc or USB drive to reinstall Windows to your computer, which is needed to format your computer's hard drive and start over. Likewise, if you're installing a new hard drive on your computer or laptop, you need this bootable disc or USB drive to install a fresh copy of Windows.
