Windows 8.1 is available for download via USB drive, but it hasn't been officially released on CD yet.
I checked how it might actually work and I believe most people who have shared it agree. I found several videos explaining the process: 1, 2, 3, 4, which suggests there’s a clear method for doing it via USB. However, I still have a question—if I purchase a downloadable version of 8.1, such as this one, would it allow me to obtain the full ISO file and the key? I imagine it might be sent via email, and then I could transfer that information onto my Windows XP system. It sounds like a very specific process, so I was wondering if anyone has experience with this.
I think purchasing the download-only versions only provides a link to an ISO file and a product key. You’ll also need a tool to install the ISO onto your USB drive. Some Microsoft utilities might work, but I’m not certain they support mounting Windows 8 from XP. I’d recommend using Rufus (https://rufus.akeo.ie/). It’s a standalone app that’s straightforward. It should automatically detect your USB drive, though double-check you’ve selected the right one. Be sure nothing critical is stored on the drive before proceeding. Check the box labeled “Create a bootable disk using.” Click the CD-ROM icon to the right, go to the saved location, open the file. The default settings are acceptable; just click ‘Start.’ It may take a few minutes, but that’s all you need to do. This method applies to any ISO you require.
The only mistake you can make is aligning the ISO correctly on the USB drive. This won’t cost you money because you won’t have entered a product key. You’ll just need to erase the USB and retry. In the worst case, you might harm the drive and lose it—though that would require a serious error. Still, you should get the ISO and related files; using a CD might be better for large installations. People rarely give USBs, and I’m not confident my ISP will keep the connection steady when downloading big files. For example, I once downloaded Borderlands 2 (around 9GB) and my speed dropped so low I couldn’t stream anything smoothly.
