From Windows 1 to Windows 10

Microsoft’s Windows operating system was first introduced in 1985. Over 29 years later a lot has changed, but what things have stayed the same?

has seen nine major versions since its first release in 1985. Over 29 years later, Windows looks very different but somehow familiar with elements that have survived the test of time, increases in computing power and – most recently – a shift from the keyboard and mouse to the touchscreen.

Here’s a brief look at the history of Windows, from its birth at the hands of Bill Gates with Windows 1 to the latest arrival under new Microsoft chief executive Satya Nadella.

Windows 1

This is where it all started for Windows. The original Windows 1 was released in November 1985 and was Microsoft’s first true attempt at a graphical user interface in 16-bit.

Development was spearheaded by Microsoft founder Bill Gates and ran on top of MS-DOS, which relied on command-line input.

It was notable because it relied heavily on use of a mouse before the mouse was a common computer input device. To help users become familiar with this odd input system, Microsoft included a game, Reversi (visible in the screenshot) that relied on mouse control, not the keyboard, to get people used to moving the mouse around and clicking onscreen elements.

Windows 2

Two years after the release of Windows 1, Microsoft’s Windows 2 replaced it in December 1987. The big innovation for Windows 2 was that windows could overlap each other, and it also introduced the ability to minimize or maximize windows instead of “iconizing” or “zooming”.

The control panel, where various system settings and configuration options were collected together in one place, was introduced in Windows 2 and survives to this day.

Microsoft Word and Excel also made their first appearances running on Windows 2.

Windows 3

The first Windows that required a hard drive launched in 1990. Windows 3 was the first version to see more widespread success and be considered a challenger to Apple’s Macintosh and the Commodore Amiga graphical user interfaces, coming pre-installed on computers from PC-compatible manufacturers including Zenith Data Systems.

Windows 3 introduced the ability to run MS-DOS programmes in windows, which brought multitasking to legacy programmes and supported 256 colors bringing a more modern, colorful look to the interface.

More important - at least to the sum total of human time wasted - it introduced the card-moving timesink (and mouse use trainer) Solitaire.

Windows 3.1

Windows 1 and 2 both had point release updates, but Windows 3.1 released in 1992 is notable because it introduced TrueType fonts making Windows a viable publishing platform for the first time.

Minesweeper also made its first appearance. Windows 3.1 required 1MB of RAM to run and allowed supported MS-DOS programs to be controlled with a mouse for the first time. Windows 3.1 was also the first Windows to be distributed on a CD-ROM, although once installed on a hard drive it only took up 10 to 15MB (a CD can typically store up to 700MB).

Windows 95

As the name implies, Windows 95 arrived in August 1995 and with it brought the first ever Start button and Start menu (launched with a gigantic advertising campaign that used the Rolling Stones’ Start Me Up, and a couple of months later Friends stars Jennifer Aniston and Matthew Perry. Could it be any more up-to-date?)

It also introduced the concept of “plug and play” – connect a peripheral and the operating system finds the appropriate drivers for it and makes it work. That was the idea; it didn’t always work in practice.

Windows 95 also introduced a 32-bit environment, the taskbar and focused on multitasking. MS-DOS still played an important role for Windows 95, which required it to run some programmes and elements.

Internet Explorer also made its debut on Windows 95, but was not installed by default requiring the Windows 95 Plus! pack. Later revisions of Windows 95 included IE by default, as Netscape Navigator and NCSA Mosaic were popular at the time.

Windows 98

Released in June 1998, Windows 98 built on Windows 95 and brought with it IE 4, Outlook Express, Windows Address Book, Microsoft Chat and NetShow Player, which was replaced by Windows Media Player 6.2 in Windows 98 Second Edition in 1999.

Windows 98 introduced the back and forward navigation buttons and the address bar in Windows Explorer, among other things. One of the biggest changes was the introduction of the Windows Driver Model for computer components and accessories – one driver to support all future versions of Windows.

USB support was much improved in Windows 98 and led to its widespread adoption, including USB hubs and USB mice.

Windows ME

Considered a low point in the Windows series by many – at least, until they saw Windows Vista – Windows Millennium Edition was the last Windows to be based on MS-DOS, and the last in the Windows 9x line.

Released in September 2000, it was the consumer-aimed operating system twined with Windows 2000 aimed at the enterprise market. It introduced some important concepts to consumers, including more automated system recovery tools.

IE 5.5, Windows Media Player 7 and Windows Movie Maker all made their appearance for the first time. Autocomplete also appeared in Windows Explorer, but the operating system was notorious for being buggy, failing to install properly and being generally poor.

Windows 2000

The enterprise twin of ME, Windows 2000 was released in February 2000 and was based on Microsoft’s business-orientated system Windows NT and later became the basis for Windows XP.

Microsoft’s automatic updating played an important role in Windows 2000 and became the first Windows to support hibernation.

Windows XP

Arguably one of the best Windows versions, Windows XP was released in October 2001 and brought Microsoft’s enterprise line and consumer line of operating systems under one roof.

It was based on Windows NT like Windows 2000 but brought the consumer-friendly elements from Windows ME. The Start menu and taskbar got a visual overhaul, bringing the familiar green Start button, blue taskbar, and vista wallpaper, along with various shadow and other visual effects.

ClearType, which was designed to make text easier to read on LCD screens, was introduced, as were built-in CD burning, autoplay from CDs and other media, plus various automated update and recovery tools, that unlike Windows ME actually worked.

Windows XP was the longest running Microsoft operating system, seeing three major updates and support up until April 2014 – 13 years from its original release date. Windows XP was still used on an estimated 430m PCs when it was discontinued.

Its biggest problem was security: though it had a firewall built in, it was turned off by default. Windows XP’s huge popularity turned out to be a boon for hackers and criminals, who exploited its flaws, especially in Internet Explorer, mercilessly - leading Bill Gates to initiate a “Trustworthy Computing” initiative and the subsequent issuance of to Service Pack updates that hardened XP against attack substantially.

Windows Vista

Windows XP stayed the course for close to six years before being replaced by Windows Vista in January 2007. Vista updated the look and feel of Windows with more focus on transparent elements, search and security. Its development, under the codename “Longhorn”, was troubled, with ambitious elements abandoned in order to get it into production.

It was buggy, burdened the user with hundreds of requests for app permissions under “User Account Control” - the outcome of the Trustworthy Computing initiative which now meant that users had to approve or disapprove attempts by programs to make various changes.

The problem with UAC was that it led to complacency, with people clicking “yes” to almost anything - taking security back to the pre-UAC state. It also ran slowly on older computers despite them being deemed as “Vista Ready” - a labeling that saw it sued because not all versions of Vista could run on PCs with that label.

PC gamers saw a boost from Vista’s inclusion of Microsoft’s DirectX 10 technology.

Windows Media Player 11 and IE 7 debuted, along with Windows Defender an anti-spyware programme. Vista also included speech recognition, Windows DVD Maker, and Photo Gallery, as well as being the first Windows to be distributed on DVD. Later a version of Windows Vista without Windows Media Player was created in response to anti-trust investigations.

Windows 7

Considered by many as what Windows Vista should have been, Windows 7 was first released in October 2009. It was intended to fix all the problems and criticism faced by Vista, with slight tweaks to its appearance and a concentration on user-friendly features and less “dialogue box overload”.

It was faster, more stable and easier to use, becoming the operating system most users and business would upgrade to from Windows XP, forgoing Vista entirely.

Handwriting recognition debuted in 7, as did the ability to “snap” windows to the tops or sides of the screen, allowing faster more automatic window resizing.

Windows 7 saw Microsoft hit in Europe with antitrust investigations over the pre-installing of IE, which led to a browser ballot screen being shown to new users allowing them to choose, which browser to install on first boot.

Windows 8

Released in October 2012, Windows 8 was Microsoft’s most radical overhaul of the Windows interface, ditching the Start button and Start menu in favor of a more touch-friendly Start screen.

The new tiled interface saw programme icons and live tiles, which displayed at-a-glance information normally associated with “widgets”, replace the lists of programmes and icons. A desktop was still included, which resembled Windows 7.

Windows 8 was faster than previous versions of Windows and included support for the new, much faster USB 3.0 devices. The Windows Store, which offers universal Windows apps that run in a full-screen mode only, was introduced. Programs could still be installed from third-parties like other iterations of Windows, but they could only access the traditional desktop interface of Windows.

The radical overhaul was not welcomed by many. Microsoft attempted to tread a fine line between touchscreen support and desktop users, but ultimately desktop users wanting to control Windows with a traditional mouse and keyboard and not a touchscreen felt Windows 8 was a step back.

There were also too few touchscreens in use, or on offer, to make its touch-oriented interface useful or even necessary - despite the parallel rise of tablets such as the iPad, and smartphones, which had begun outselling PCs by the end of 2010.

Windows RT, which runs on ARM-based processors traditionally found in smartphones and non-PC tablets, was introduced at the same time as Windows 8 with the Microsoft Surface tablet. It looked and felt like Windows 8, but could not run traditional Windows applications, instead solely relying on the Windows Store for third-party apps

Windows 8.1

A free point release to Windows 8 introduced in October 2013, Windows 8.1 marked a shift towards yearly software updates from Microsoft and included the first step in Microsoft’s U-turn around its new visual interface.

Windows 8.1 re-introduced the Start button, which brought up the Start screen from the desktop view of Windows 8.1. Users could also choose to boot directly into the desktop of Windows 8.1, which was more suitable for those using a desktop computer with a mouse and keyboard than the touch-focused Start screen.

Windows 10

Announced on 30 September 2014, Windows 10 has only been released as a test version for keen users to try. The “technical preview” is very much still a work in progress.

Windows 10 represents another step in Microsoft’s U-turn, bringing back the Start menu and more balance to traditional desktop computer users.

Some interesting features include the ability to switch between a keyboard and mouse mode and a tablet mode, for those computers like the Surface Pro 3 with a detachable keyboard.

Windows 10 – despite being the ninth version of Windows – is designed to unify all Windows platforms across multiple devices, including Windows Phone and tablets, with universal apps that can be downloaded from the Windows Store and run on all Windows devices.

It won’t be available until 2015, likely after Microsoft’s Build developer conference in April, so for now Windows 8.1 is the latest version of Windows

Start menu

After complaints from users about its absence, the start menu is back. Clicking the start button brings up a menu, which – although isn’t exactly the same as Windows 7 or those before it – is more familiar than the full-screen tiled interface of Windows 8. This should be much more useful for desktop users, but the tiled interface from Windows 8 is tacked on to the side.

Continuum

Windows 10 attempts to blend the best of Windows 7 with Windows 8. One of the smartest things Microsoft has added is Continuum, which detects the state of the computer and presents the right interface depending on whether a keyboard and mouse is being used or the screen is being touched.

For machines like the Surface Pro (which has a detachable keyboard), when the keyboard is attached it behaves like a desktop machine; without it, Windows switches to a more touch-friendly interface with an on-screen back button and other touch elements to make things a bit easier with fingers on a screen.

One Windows for all devices

Microsoft has talked a lot about Windows being more than simple desktop computer software. Windows 10 is meant to unify desktop PCs, Windows tablets and Windows Phone smartphones with one interface, one way of operating and one account.

Apple has taken a similar route with its iCloud accounts and the upcoming Continuity feature between iPads, iPhones and Mac computers – although its iOS software on the iPhone and OS X on the desktop have been kept separate.

 Universal apps

Along with the “one Windows for all devices” idea, Microsoft is pushing what it calls “universal Windows apps”, which is the new name for apps downloaded from the Windows Store. The idea is that one app will be able to run on all Windows platforms, including Windows Phone. Microsoft has been talking about this for over a year.

How it will work is not yet clear, but it is likely that new Windows apps will have a condensed version for Windows Phone and full-size versions for tablets and computers. Apple’s universal apps do something similar between the iPhone and iPad but are not the same as the desktop OS X apps.

No more full-screen; universal apps can be windowed

Bringing back the start menu has given the traditional Windows desktop more prominence again. To help merge the Windows 8-style “modern” apps from the Windows Store with the traditional desktop, Windows 10 can now run the newly renamed “universal apps” in windows on the desktop, as though they were any other desktop app.

 Snap assist

The snapping feature, which automatically resizes windows on the desktop to fill part or all of the screen, has been enhanced, allowing tiling of windows, snapping side-by-side and an array of new layouts to including virtual multi-desktop modes to try to help computer and tablet users be more productive with both universal apps and traditional desktop Windows apps.

 What will it run on? Is Windows RT dead?

Windows 10 will run on most things that Windows 8 can run on. That includes almost any new PC bought in the last couple of years but will exclude some older PCs, as Windows 8 requires a 64-bit processor.

Processors supporting 64-bit operation have been on sale from Intel and AMD since 2004, so most PCs still in operation will support 64-bit software.

The fate of ARM-based Windows tablets (that is, not running x86 processors) is unclear. Windows RT powers the Microsoft Surface and Surface 2, Nokia Lumia 2520 and the Dell XPS 10, among others. Microsoft has yet to announce whether Windows RT, which only runs on tablets powered by smartphone-class ARM processors, will be upgraded to Windows 10. A question about RT’s future wasn’t answered at the introduction on Tuesday.

When will it be available, and what will it cost?

Microsoft showed off Windows 10 on Tuesday, but it won’t actually be available to users until 2015, after Microsoft’s developer conference in April called Build. Microsoft will be courting businesses before consumers, but Windows 10 is unlikely to appear in most businesses until the end of 2015 at the earliest.

Most consumers will buy Windows 10 with a new PC, but for those feeling adventurous and wanting to have a poke around Microsoft’s latest and greatest, the company is allowing users to sign up for early previews of the software still in testing.

It is recommended only for those that are happy to deal with and tech-savvy enough to cope with buggy software and the potential for data loss, but those interested can check out the Windows Insider Program.

How much the final retail edition of Windows 10 will cost Microsoft hasn’t said. Windows 8.1 costs £100 from Microsoft, but a Windows 10 introductory discount is likely.

 What’s in a number?

Yes, Microsoft did skip from Windows 8 (or 8.1 to be precise) straight to Windows 10.

What happened to Windows 9? Perhaps Microsoft has been using base 9, so 9 is 10. Or 10 just sounds better? The Xbox 360 (aka the Xbox 2) and its successor the Xbox One (aka the Xbox 3) are proof that Microsoft is happy to throw out conventional numbering when it feels like it
