Somebody has taken a version of Word from 1990 and created a fully functional port for Windows 11 — and as you might imagine, this is a word processor with an incredibly light footprint.

Tom's Hardware noticed this feat, which was achieved by Justin Marshall, who's the developer behind the 'Microsoft Word for Windows 1.1a' project on GitHub.

As Marshall explains, this is not an emulator or some kind of fudge, rather it's a "fully working native Windows x64 port" of Word for Windows 1.1a which was codenamed 'Opus' back in the day.

This port was possible because Microsoft released the source code for the app (over 10 years ago), and Marshall took that code and ran with it. (As Tom's notes, it's available from the Computer History Museum).

Marshall explains that the project builds on that original Word source code (and complementary resources) with "modern replacements for the 16-bit assembly, segmented-memory, and Win16 platform boundaries".

The result is a very simple word processor that takes the idea of a streamlined app to new levels. Indeed, this modern take on Word for Windows 1.1a can fit in less than 1MB of RAM in Windows 11. How's that for lean? And there's not a drop of AI in sight…

Analysis: Word up

Can those fed up with Microsoft's feature-creep in Notepad, or other bloat, go and pick up this spin on Word from 1990 for a breath of fresh air in terms of a lightweight word processor? No, unfortunately, as there's no installation package to simply download and fire up.

That's because, as Marshall points out, the "historical source files retain their original Microsoft and third-party copyright notices", which means that commercial use or even sharing copies on the web isn't permitted.

This is why if you want to use Word for Windows 1.1a on your modern PC, you'll need to get it up and running by following the instructions on GitHub. This isn't for the technically faint-of-heart, as you might guess, and you'll need Visual Studio 2022 with Desktop development with C++, a Windows 11 (or 10) SDK installed through Visual Studio, as well as CMake 3.25 (or newer) and PowerShell.

In short, it's unlikely that many people will go to the effort, but it's not surprising that a fair bit of interest has been stoked in this project simply because of not just the novelty — although that's obviously the driving factor — but also as it's an illustration of how far Word can be stripped back, running with such a tiny footprint and resource usage.

One Redditor commenting on this simply said: "Not all heroes wear capes."

Another observed: "For the curious, Microsoft Office 97 will install and run on Windows 11 with no hassle. I've been using it for years now just for the fun of it."

Bear in mind, of course, that should you take that approach, you'll be lagging behind considerably for supported file formats, and also in the security stakes (that's the main drawback with using apps that haven't been updated in a long time, and lack patches against exploits that have since popped up).

If you are keen on a lightweight alternative to Notepad, then take a look at TinyRetroPad, which is built very much in the same vein as the original Microsoft text editor, and is just as tiny as the name suggests.
