The Early Versions, Windows 1.0 and 2.x
Released in 1985, the first version of Windows wasn't really considered a full blown operating system, lacking features like memory management. But it did support basic multitasking and introduced API standards that allow programs that run in Windows 1.0 to work all the way to the latest version with little tweaking or minor recompiling if necessary. While it did have windows to display applications in, due to patents held by Apple, Windows 1.0 could not have overlapping windows. Needless to say, the first version wasn't very successful.Windows 2.0 was released two years later, which improved on the graphical interfaces, such as allowing overlapping windows and minimizing and maximizing them. A plethora of apps came with the OS, including a calendar, contacts, and Reversi. It also supported the new VGA standard, but only 16 colors were available. Windows 2.0 sold much better than the first version, though software developers still maintained DOS versions of their programs. Windows 2.0 was also still heavily dependent on DOS to manage hardware resources, including a memory access limitation of 1 megabyte.
Of course, the use of patented overlapping windows caught the attention of Apple, and they filed a lawsuit over it in 1994.
Windows 3.0 and 3.1
Windows 3.x is where Windows really took off. 3.0 was released in 1990, designed to take advantage of protected memory support as well as better driver support. This allowed programs to behave better when run simultaneously as well as access more memory. The user interface was given many improvements as well. A year later, Microsoft added multimedia extensions to take advantage of CD players being available to computers.The only issue with 3.0 was that it was fairly crash prone, as the minimum requirement was the 8086 processor, which lacked certain key features. In 1992, Windows 3.1 was released, requiring at the minimum a 286 processor and 1MB of RAM. This helped increase stability quite a bit. Other features included support for the new TrueType Font standard, multimedia playback capabilities, and basic networking. User interface improvements included the ability to drag and drop icons, for instance, dragging a Word document to a printer and having it print out.
Despite all of the improvements, many games at the time still used DOS for its more 'direct' ways of accessing resources, especially since there wasn't a reliable API that could render graphics as fast as it was on DOS. There was WinG (pronounced as "win-gee") which aimed to solve developers' issues porting games to Windows, but a high-profile incident with Disney's Animated Storybook: The Lion King where Compaq Presarios that came with certain video drivers ended up with a Blue Screen of Death (much to the chagrin of parents who had to deal with their children wailing uncontrollably over a game that failed to work as intended) led Microsoft to develop DirectX in 1995.
Microsoft Goes Pro: OS/2 and Windows NT
In 1988, Microsoft and IBM started working on a workstation centric operating system later dubbed OS/2. It was an ambitious effort to simplify software development so that, for instance, the program no longer had to go through BIOS to access hardware, it could call it from the OS. It was also designed to be multitasking, much like UNIX.However, the relationship ended in 1990. Windows 3.0 took off and sold millions, mostly because it was bundled with computers while OS/2 was an expensive upgrade. Microsoft also favored open hardware platforms while IBM wanted to restrict OS/2 to just their computers. But Microsoft took all of these ideas that were good from OS/2, took all the ideas that were good from Windows 3.0, and started from scratch to build a new operating system kernel: Windows NT.
Windows NT was designed from the ground up with the prospect of being portable to other processor architectures of the time, secure and more stable than the Windows that ran on top of MS-DOS, and with networking. Other features included the concept of security levels for users (so that a user cannot crash the operating system) and compatibility with OS/2 and previous Windows applications.
Microsoft didn't intend for Windows NT to replace Windows 3.x, instead it was a companion product for those with high end systems who wanted the features, namely the professional sector.
The Menu to Rule Them All: Windows 95, 98, and Me
Microsoft continued with their consumer versions of Windows on top of MS-DOS. The next version was Windows 95, introducing the one noticeable feature that set the trend for a lot of other desktop based interfaces: the Start Menu. While initially confusing for some users, the Start Menu was where most of the applications and settings could be found and accessed. Of course, there were other technical improvements as well, such as being 32-bit, supporting plug-and-play hardware, preemptive multitasking, and increased stability.Windows 98, released three years later, added improvements to hardware support and internet connectivity. However, the MS-DOS based Windows came to a crash following the release of Windows Millennium Edition, or ME. It was buggy, unstable, and while it did introduce some neat features (such as System Restore), many people hated it and stuck with Windows 98.
Aside from that, Windows 9x and ME had their share of problems. The world became familiar with the Blue Screen of Death, a fatal system error which was a very common occurence. Infamously, during a live demonstration of Windows 98, the OS crashed while attempting to show off its plug and play features, to which Bill Gates quipped "That must be why we're not shipping Windows 98 yet"... after applause and cheering. Much of this could be attributed to how Windows did backwards compatibility, dubbed DLL Hell.
Windows 2000 and XP, Keeping the Crown
Windows NT continued development alongside Windows 95, 98, and ME. As it was not dependent on DOS, it enjoyed more stability and security. Windows 2000 introduced a laundry list of features, including some from Windows 98, and improved hardware support for USB devices. It was also the first Windows to protect key files from being overwritten. However, security was an issue as the internet grew in this period and hackers found security holes to exploit the OS. Despite all this, those who've used Windows 2000 regularly claimed it was the best Windows OS, even after the release of the next version, Windows XP.Windows XP was the first NT version of Windows with consumer support with the Home version. It also had a Professional version for businesses and the like. XP rapidly rose to usage after Service Pack 1 was released, mostly due to increased stability (it was practically immune to DLL Hell) and compatibility with previous Windows programs. Key changes were also made to the user interface, such as the Start Menu and Windows Explorer.
Not everything was sunshine and roses, though. Because of its popularity, it was a common target for computer viruses. It didn't help that few people understood the concept of privileged user accounts. By default, Windows XP user accounts are administrators, which means that a program that runs has free rein over all OS resources. These issues were primarily used as ammo by Apple to gain popularity for its "virus immune" OS.
Microsoft Stumbles, Then Picks Up the Slack - Windows Vista and 7
Vista had a long history, starting development all the way back in 2002. Microsoft wanted to implement ambitious features for the time, including a relational database-like file system WinFS and a radically new API for the interface. Security was also a primary concern of Microsoft, so that was kept in mind as well. However, feature creep kept delaying the operating system over and over again, and features had to be dropped. It didn't help that Microsoft started to look outdated with the release of Mac OS X 10.4 in 2005. Years too late, Microsoft finally released the new OS as Windows Vista. It was bloated, required more resources than the average computer had at the time to run smoothly, and one of the touted new security features, User Account Control, was seen as annoying and was a key reason for some to skip the OS.Of course, Microsoft wasn't going to let Apple take the spotlight, and quickly reworked and optimized Windows Vista into Windows 7. Windows 7 was well received, being referred to as "what Windows Vista should've been". While Windows 7 was only an incremental improvement on the list of features available from Windows Vista, the user interface was improved, and by the time it was released, the average computer could actually run it smoothly.
Microsoft Goes Metro - Windows 8(.1)
A few years prior to 2012, Microsoft had a few portable media players called Zune. Though it didn't put a dent in Apple's dominance with the iPod, it had a notable feature that turned heads: its user interface. Dubbed Metro (after being inspired by signs from Seattle's metropolitan transit system), it focused on clean, flat topology with emphasis on efficiency, using actual content as UI elements. A lot of publications felt that this was a good competitor against Apple, to which even Apple started to take cues and started suing companies who were allegedly copying their iOS design.With the rise of tablets and other portable devices, Microsoft felt it was necessary to unify the user interface so that it was consistent across any Windows powered device. Windows 8 adopted principles of Metro and replaced the Start Menu with the Start Screen. This screen filled up the display with an array of icons, some with apps that showed relevant content (such as a weather app icon showing... well, the weather).
Despite the positive reaction from Metro, there was much criticism regarding using it for desktop based environments and it was clear that the language used in Windows 8 was tailored to touch devices, not keyboards and mice. Metro apps could only run full-screen or share the screen with one other Metro app, angering desktop users. While Windows 8 does improve on Windows 7 in underlying areas, most people criticized the Start Screen and used it as a reason to avoid Windows 8, even calling it the next Vista. The criticisms of Windows 8 led to the release of Windows 8.1 in 2013, a service pack-like release which featured an improved Start Screen, the return of a visible Start button on the taskbar, improved and expanded app snapping views, better integration of Microsoft's cloud storage service OneDrive (formerly named SkyDrive), native support for 3D printing, and several other new features and improvements.
A Return to the Basics - Windows 10
Still, after seeing the immense criticism that Windows 8 faced, Microsoft decided to go on a different development path with the next version of Windows, which they surprisingly named "Windows 10", skipping "Windows 9" note . Microsoft launched the Microsoft Insider program in September 2014 to allow the public to beta test the new version of Windows as it was developed. Several betas went out to the Insider Program members, who were also the first to receive the completed operating system when it released in July 2015.Windows 10 re-introduced the Start Menu, now a combination of the older style Start Menu as well as Windows 8 style apps. It allowed Metro apps to run windowed, alongside regular Windows programs. It also introduced Microsoft's voice assistant Cortana to computers. Microsoft was so confident that Windows 10 would be successful that it offered free upgrades to anybody running Windows 7 or Windows 8. Sure enough, it was on nearly 40 million computers by the end of 2015.
Unlike previous versions of Windows, Microsoft treated it more like a live-service than a single OS release, foregoing the traditional "service pack" model and instead releasing major updates containing new features on a bi-annual basis, along with the usual weekly bug fixes and security patches via Windows Update.
Keeping Up with the Times - Windows 11
Despite Common Knowledge that 10 would be the "last" version of Windows note , Microsoft created a new version at the beginning of The New '20s, coincidentally around the same time Apple finally upgraded Mac OS to Version 11 after 20 years. Originally developed as an alternative version of Windows 10 for Laptop/Tablet hybrid devices titled "Windows 10X" with a UI that mirrored the look and feel of Mac OS 11 and Chrome OS, it was instead retooled into the next major version for all devices following the increase in demand for traditional PC's during the COVID-19 Pandemic.
Windows 11 introduced a completely new Taskbar and Start Menu that were far simplified from that of Windows 10, such as completely doing away with Live Tiles and instead introducing small simple launch icons, along with expanding the "Snap" feature first seen back in 7 to new "Snap Layouts" to offer better multitasking.
Similar to the release of 10, Microsoft offered 11 as a free update when it released in fall 2021.
Games
This list is sorted by minimum OS version necessary (at least, the one listed on Minimal Requirements). Many of these will still be compatible with later versions, but some may not. Games that are compatible with DOS and Windows should be listed on the IBM Personal Computer page under DOS Games. Web Games should typically be listed on that page since they're often playable on all systems as just about all internet browsers on all systems should be compatible. Theoretically, a modern machine is compatible with all of the games listed; however, many need fixes due to changes that have been made over the past 25 or so years, with the very old 16-bit ones requiring an emulator on 64-bit systems due to support being axed.Sorted by minimum required OS
