The video pairs PowerISO with Rufus as if they were the same kind of free tool. They are not, and this page says so plainly - while also giving PowerISO its due, because for image work beyond bootable USBs it does things Rufus cannot.
Honesty first, because this is where most write-ups fudge it: Rufus is free; PowerISO is a trial of a paid product. That does not make PowerISO bad - it makes the comparison worth doing properly. Below: what the trial actually restricts, the jobs where PowerISO is the strongest tool on the desk, and the one job - installer USBs - where the free tool wins outright.
PowerISO is not really a bootable-USB tool that grew extras - it is a complete disk image workshop that happens to include one. It opens, creates, edits, extracts, converts, encrypts and burns image files in almost every format in circulation: ISO, BIN, NRG, CDI and its own compressed DAA format. It mounts images as a virtual drive so you can browse them without burning anything, and it burns real CDs, DVDs and Blu-rays too. The bootable USB writer lives under Tools > Create Bootable USB Drive.
PowerISO is shareware. The unregistered version is a trial with two honest limits: a registration reminder dialog appears when the program starts, and it cannot create or edit image files larger than 300 MB. The maker states that all other functions work the same as the registered version - and that includes writing a bootable USB from an existing ISO. So yes, the trial can follow the video's method. But if the program becomes a permanent resident of your PC, the right move is a paid licence from the official site. Anyone offering you a cracked full version is offering you the single most common way this software gets bundled with malware.
There are jobs where PowerISO is honestly the better tool on the desk. Editing an ISO - adding a driver folder or a licence file into an image before burning - is something Rufus simply does not do. Odd formats like BIN, NRG or DAA open here when other tools shrug. Mounting an image as a virtual drive to grab one file takes seconds. And if you still burn optical discs, PowerISO handles the whole workflow in one program. If your work is images in general, not just installer USBs, that breadth is the product.
For the specific job of this video - an installer USB - the comparison tilts. Rufus is free with no limits, a portable file of a few megabytes that needs no installation, and it exposes the partition scheme, the setting that decides whether a given PC boots the stick at all. PowerISO's USB dialog chooses everything itself. When it works, that simplicity is pleasant. When a particular PC will not boot the result, you have no controls to adjust - your only move is to switch to the tool that has them. Rufus is that tool.
Download PowerISO only from poweriso.com. During setup, choose the custom path when offered and decline any extra bundled software - like many long-lived shareware installers, the setup may present optional offers, and clicking through blindly is how toolbars and trials of unrelated products land on a machine. It takes ten extra seconds to read each screen. Needless to say, a so-called free full version from a crack site is worse than any bundle: that route is a documented malware delivery channel.
Own PowerISO already, or need an image editor that also writes bootable USBs? Use it with a clear conscience - its USB writer does the job. Starting from zero for a Windows installer? Download Rufus. It costs nothing, asks the right questions, and gives you the one control - partition scheme - that decides success. The video shows both tools because a technician's desk accumulates both; your first tool should be the free, precise one.
Both tools are shown live in the video - every click, every setting, and the first boot from the finished USB.
▶️ Watch Full VideoIt is free to download and try, but it is not free software. PowerISO is shareware: the unregistered version shows a registration reminder at startup and cannot create or edit image files over 300 MB. A licence is a one-time purchase from the official site - check poweriso.com for the current price rather than trusting figures quoted elsewhere, as prices change.
Yes. The 300 MB trial limit is about creating and editing image files inside PowerISO, not about writing an existing ISO to USB. The manufacturer states that all other functions are the same in the unregistered version, and the bootable USB writer is one of those functions. Expect the startup reminder dialog, and expect to need administrator rights.
The program itself, downloaded from poweriso.com, is a long-established legitimate product. The danger lives in the copies: cracked and repacked versions from download portals are a well-known malware route. Download from the official site, read the installer screens, decline bundled extras, and the tool is as safe as any mainstream utility.
