Microsoft's decision to have a common operating system blueprint that can run from an internet-of-thing device to a (super) computer means that Windows 10 has been built from the ground up to run comfortably on low-performance parts.

The fact that it shares the same minimum hardware requirements as Windows Vista (at least for the Premium experience) is a fantastic achievement but that's only part of the story; Windows 10 actually runs better than its beleaguered ancestor. Much better.

We tried an experiment at TechRadar to see how low Windows 10 could go. I sourced the most ancient (but probably not the slowest) processor that could run it. Microsoft says that it needs to have at least a 1GHz clock rate with IA-32 or x64 architecture as well as support for NX bit, PAE, and SSE2.

The oldest processor that fits the bill is the AMD Athlon 64 3200+, a part first introduced to the market in September 2003, 11 and a half year ago. It's slow (about half the Passmark score of the Baytrail-based Intel Atom Z3735G found in many entry level, sub-100 tablets) but I chose not to underclock it.

The computer that housed it is a Mesh computer, one that comes with an Nvidia-powered Asus motherboard with onboard graphics, four 256MB DDR memory modules, a 40GB hard disk drive, a DVD ROM drive and even a floppy disk drive.

An antiquated Mesh PC computer is the host.

Installing Windows 10 TP proved to be a straight-forward task. Load it on a USB drive containing Windows 10 (you can use this Windows 7 USB drive tool) and voila! The whole process didn't take longer than on any other recent machine we loaded with Windows 10. Well done to Microsoft for maintaining compatibility with hardware that's more than a decade old.

Once in, I wired the computer and downloaded the latest drivers, still no hiccups. Even with less than 1GB of RAM (64MB of it is shared with the video subsystem), Windows 10 is surprisingly nice to use, which bodes well for anyone looking to get it running on an old computer.
