Windows 3.1 is 30 years old | Custom PC #226

Screensavers, colourful icons and proper fonts. 30 years after its release, Stuart Andrews looks back at the version of Windows that finally put it on the map.

Windows 3.1 is arguably the most crucial Windows ever – the Windows that defined how PC computing looked just as it was beginning to take off. Before version 3.1, Windows was a successful operating system, but one that looked and felt like a GUI shell perched precariously on DOS. 

Cue a sigh of relief when this splash screen showed up. Launching Windows from MS-DOS could be s…l…o…w

With the launch of Windows 3.1 in April 1992, Windows finally looked and felt like the real deal. What’s more, it was a sales phenomenon, shipping over 3 million copies in its first six weeks on the market and 25 million within the first year. Windows was already big, but 3.1 put Windows in the lead. 

How did Windows 3.1 do this? That’s not something you can nail down to any one factor. It was partly a question of stability, partly features and partly look and feel. Believe us – Windows 3.1 looks rough by today’s slick standards, but not half as rough as what came before.

Look and feel

Look and feel certainly played an important part in Windows 3.1’s success. Windows 3.0 has already done some of the hard work of introducing a proper GUI, replacing the horrible, text-based MS-DOS Executive of Windows 1.x and 2.x with the new Program Manager and File Manager components. Instead of clicking on a program or a file in a list, you could double click on an icon to launch it. Yet Windows 3.1 went further, taking advantage of the VGA and SVGA graphics standards to introduce a revamped UI with more colourful icons.

The Program Manager was the heart of Windows 3.1. Double clicking icons launched the applications, or you could drag and drop files onto the icons or open windows

What’s more, those icons could now do more than just get clicked on, as Windows 3.1 introduced drag and drop. You could explore your PC’s file system visually, copying files from one folder to another by clicking on the file, dragging it over and releasing the mouse button. You could drag a file onto the Print Manager icon to print it out, or onto the application’s icon in Program Manager to open it and start work. 

Yet perhaps the most vital enhancement over Windows 3.0 was the introduction of TrueType fonts. At this point, Windows still involved a lot of text and, up until Windows 3.1, this text didn’t look good. It was pixelated, primitive and ugly, with no real provision to vary horizontal or vertical spacing. 

While developing Windows 3.1, Microsoft put a team together to fix this problem, and that team worked with one of the two leading typesetting companies of the era, Monotype, to design a new set of core fonts. Meanwhile, Microsoft worked on the technology to render those fonts on-screen, so they could be scaled upwards and downwards, rotated and respaced, and still look pretty good. 

TrueType fonts were a revelation to Windows users, making the OS look significantly better and opening up more sophisticated WYSIWYG DTP and design applications

Monotype came up with the Times New Roman, Arial and Courier New fonts that Windows still incorporates today, while Microsoft licensed and adapted Apple’s TrueType technology, adapting the font hinting tech that made these fonts clear and legible even on a VGA resolution ( 640 x 480 ) screen. This not only made Windows look a whole lot better, but made it a viable platform for desktop publishing and design. Suddenly, the Mac had competition. 

Fun and games

Other aspects of Windows 3.1 revealed a more playful side to Microsoft. Windows 1.0 includes one game – Reversi, while Windows 3.0 introduced Solitaire, a patience card game originally developed by a Microsoft intern, Wes Cherry, and responsible for so much lost productivity that Microsoft banned its ‘boss key’ feature, which switched from the game to a mocked-up Excel spreadsheet, before release.

Windows 3.1 added Minesweeper, the classic game of grid-based bomb discovery so addictive that, legend has it, Bill Gates had it uninstalled from his PC. Not that this stopped him or anyone else playing it. While Gates was known to sneak onto a colleague’s computer after hours to play it, the rest of the company joked that Minesweeper was the most carefully tested of all Windows 3.1’s new features.

This was also the first version of windows to include a built-in screensaver. As with so many new features, this wasn’t all that new – screen burn-in was an issue for CRT-based VGA monitors, and After Dark’s fish and flying toasters had already appeared on Windows 3.0 and macOS. However, Windows 3.1 made screensavers a standard component, introducing long-time favourites, such as the classic flying Windows logo, the Star Trek-style Starfield, and the psychedelic Mystify and Swirl. Seriously. After few too many shandies, they blew our primitive, PC-loving minds.

Architectural improvements

Yet the most important features that Windows 3.1 introduced were those you couldn’t see. Windows 3.0 had introduced protected memory – a way of using the protect mode of the 80286 CPU to allow Windows and Windows apps to use up to 16MB of RAM rather than just the first 640KB. 

Coded by ex-physicists David Weise and Murray Sargent, this feature had been crucial, making Windows a viable alternative for Microsoft to working with IBM on what would become OS/2. Running in protected mode gave Windows programs more stability, and enabled MS-DOS applications to run under Windows and still access all the available RAM. This in turn meant that Windows spent less time crashing, which made it a lot more attractive to people trying to get some actual work done.

Windows 3.1 gave us new ways to customise our desktops, although not much of any value with which to customise them

Windows 3.1 built on this foundation by taking the new memory management features built into the newer 386 processors and using them in a 386 Enhanced mode. Where Windows 3.0 was limited to a maximum of 16MB, Windows 3.1 upped that limit to 256MB (or, in theory, up to 4GB) and enabled programs to use virtual memory above and beyond the physical memory installed. 

It also enabled most DOS programs to be run inside a Window with mouse support, and multiple DOS programs to be run simultaneously. What’s more, all these enhancements meant Windows 3.1 only worked on an Intel 80286 CPU or later. Rocking an old-school 8086? Tough.

These changes improved not just Windows’ overall stability, but its multi-tasking capabilities as well. Applications mostly got the resources they needed, and a central messaging system alerted them to hand over resources as and when they were needed, although not all Windows programs behaved as well as others. A Task List enabled you to see all the currently running programs and halt any that were gumming up the system, although the more likely outcome was that they would crash Windows first.

What’s more, all of this went hand in hand with another major Windows feature. Windows already had the Dynamic Data Exchange (DDE) protocol, which allowed you to take messages and/or data from one Windows program to another. Windows 3.1 went one better with Object Linking and Embedding (OLE), which enabled you to embed an object created by one application into a document created by another, with both apps updating seamlessly when you made any changes. 

This was as exciting and intuitive as file management got in Windows 3.1. Notice those old-school 8.3 character filenames

Suddenly, you could create a chart in Microsoft Excel and stick it in your Microsoft Word report, then update the data in Excel and see the changes rolled out in Word. I know. It doesn’t sound that thrilling, but at the time, this rocked the computing world. 

Last, but not least, Windows 3.1 gave the world the Windows registry. At the time, this central database of settings wasn’t all that well known or understood, and we never felt the need to edit it directly as we would in the Windows 95 years. Still, it showed a willingness to gather vital system information and preferences in one place, rather than in a horde of SYS, INF and INI files, as had been the Windows way until this point. 

Confounding issues

Let’s not heap too much praise on Windows 3.1; it still had its fair share of issues. One was that Windows still didn’t support long filenames, so both files and directories were limited to names eight characters long, followed by a three-character suffix that told the OS what kind of file it was. This meant users became ingenious at truncating filenames, which in turn made looking through a folder full of documents or save games feel like decoding some esoteric text.

What’s more, while Windows 3.1 had support for multimedia hardware, which was just about becoming affordable and available, ease of installation wasn’t on Microsoft’s list of priorities. Restrictive hardware didn’t help – these were the days when solving hardware conflicts involved moving jumpers from pin to pin to swap Direct Memory Access channels. However, Windows 3.1 made the whole process of installing drivers for a CD-ROM drive and sound card as challenging as possible – it might take hours to get the whole setup running.

“WinG worked on a technical level, as proven by a WinG port of id Software’s Doom.”

Networking wasn’t any better either, because Windows 3.1 didn’t have any built-in networking support. Instead, it piggy-backed on networking clients for the underlying MS-DOS operating system. If you hadn’t already mastered Novell Netware or Microsoft LAN Manager, you were still going to have to get to grips with them here.

Nor was the Windows shell ideal. Simply finding a program in Program Manager could be daunting, especially if you weren’t sure which folder or group held it. With screen space at a premium, you would have to constantly minimise and restore Windows while you looked. Don’t even ask about finding files in File Manager.

Most of all, Windows wasn’t a great platform for games. Dodgy drivers and the massive overheads involved in just running Windows itself made it much, much easier to run Wolfenstein 3D or The Secret of Monkey Island 2 in DOS, which Windows needed to run anyway and for which all Windows users had to pay. This also meant that getting games running still required tinkering at text editor level with a range of crucial system files, to the point that most PC gamers were on intimate terms with config.sys, himem.sys and autoexec.bat. Windows 3.1 didn’t change this one bit.

With time, there was some movement. In 1994, Microsoft released a new API, WinG, which was designed to deliver faster graphics performance under Windows and encourage more developers to port their DOS games. WinG worked on a technical level, as proven by a WinG port of id Software’s Doom. Yet it didn’t work so well on the commercial level, with developers looking at the work involved and the existing DOS user base, then shrugging their shoulders until Windows 95 and DirectX came along. 

Still, for all these faults, Windows 3.1 was a major leap in the right direction, paving the way not just for Windows 95, but for the switch from IBM and OS/2 towards Windows NT. Without that we might never have had the PC boom of the mid-1990s, Windows XP and everything beyond. And where would we all be without that?

I still have Windows 3.1. I was building 8086 long time ago.

Windows 3.1 and previous were not really operating systems. They were just (arguably) pretty user interfaces for MS-DOS, or “operating environments”, that all relied on MS-DOS.

Windows NT 3.1, on the other hand, was a proper operating system (released in 1983) and laid out the path for NT 4, 2000, XP, 2003 Server, Vista, etc.

Windows 95 still relied on MS-DOS to boot, but then it took over and did everything on its own, including proper multitasking and even hardware plug-and-play later in its life cycle.
That said, as clunky as Windows 3.x is, I still love it. It’s nostalgia mostly, I’m sure, but everything was much simpler back then. I could fit MS-DOS and a rudimentary Win 3 on a 1.44 MB floppy. :) Not the greatest use of a full floppy disk, but impressive to see nonetheless.

I remember my first PC back in the day it had a 500meg hard drive i paid extra for, and thought wow this will last forever as i’ll never be able to fill it, nowadays some word docs are more than that lol

Acorn with its RISC OS machines (and an ARM CPU!!!) had properly aliased fonts and drag and drop filing well before the clunky Windows 3.1 versions. What RISC OS lacked was protected memory and true pre-emptive multitasking.

Avatar

As a current RISC OS user on Pi 400 I find I don’t miss pre-emptive or protected memory at all!

Excellent. Forgot to mention the Acorn file servers C:1984 provided secure logins, user areas, true hierarchical directories, long file names and 32bit file sizes, and, most importantly, worked! Windows 3.x networking was a nightmare. Sharing dos drives with minimum security options , 😡, I naively expected much better. NT4 was far more significant than 3.x

Unfortunately what it really lacked was financial backing and a full ecosystem of business software

For those of us who couldn’t afford Apple’s Macintosh, Windows was great and helped made them accessible to non-techies, such as myself.

Novel Netware. I remember having to secure it by cloning the default admin user to a less obvious user name with a proper password, then writing a login script for the default admin user to log the user out as soon as anyone logged in on it.

Wow, 30 years. How proud i was in this times to have a PC with Windows 3.1 :-D

Wish I could try out Windows 3.1 seems pretty cool :)

Wow Windows has truly changed a lot. From MS Dos that was just text based to having a desktop environment that looks modern. Not a Windows fan but I can see that they worked really hard at making Windows the best. :)

I recently ditched my last PC that still ran Win 3.1. Top of the range back then, but a sad heap when I got rid of it!

I wonder if we’ll have a celebratory article when Windows Me hits its 30th anniversary?

I am 84 years old and a collector of things I don’t want to give up. I still have 20 IBM PCs, five different models all made before 1985. I have two Windows 3.1 PCs, one is a dell laptop with NO USB ports because USB had not been invented yet. The other 3.1 system is an NEC dektop. I still have the original Windows 3.1 diskettes and I also have it on a CD. I also have all the manuals for them. Everything works! I use them once in a while for developing prgrams with Borland Turbo C.

“Last, but not least, Windows 3.1 gave the world the Windows registry.”
Are you sure? I remember having to start dealing with the registry in NT4.
The registry first appeared In Win95 I think.

Try “windows 3.1 registry” in Google Images. :)

I had it running for a few years on my 20Mb hard drive and had plenty of room left over.
