The drive also serves as a “clean” reinstallation of the operating system if it’s become too slow as a result of accumulated garbage.Įxperienced computer experts and IT professionals also like to use a bootable USB as a “ portable operating system” (the concept is known as “Windows2Go” for Microsoft).
You can also use a bootable USB to upgrade Windows 7 or 8 to Windows 10 if a previously automatic upgrade doesn’t function correctly. Even if no such PC emergency is present, it’s a good idea to have a Windows image for data backup on a USB-capable storage medium (could also be an external hard drive) on hand.
