A few years ago, when it comes to installing windows 10 on a computer/laptop the first thing that peeps on everyone’s mind was a disc, CD- or DVD-ROM, or the floppy disc. But at present, all these things are gradually disappearing from the tech industry. At present, most of the time the operating system is preinstalled on the system partition of a new computer/laptop or the user acquires Windows directly from online.

There are many reasons to have a bootable USB device. You can not even imagine, this small piece of hardware will become your ultimate lifesaver in the most critical situation of your computer. For example, suppose your pc no longer starts itself because of a virus, defective hard drive, serious system failure, or partition problems. In that situation, you can easily recover the windows through this portable USB drive and successfully reboot and repair the computer.
If your pc becomes slow because of auto-installing malware, key-logger, or other suspicious viruses you may need to install software to remove malware from your pc. But sometimes it is not possible to remove fully all these malware/viruses. Then you need to make a clean install of windows. As a portable USB is handy and easy to use, it will definitely become your lifesaver.
