For decades, Microsoft Windows has been the most common operating system on desktop and laptop computers around the globe. It’s the OS most people learn first, and it has the widest support for software and games. This section explores its journey, from a beloved classic to its modern, AI-integrated form.

Chapter 1.1: Windows 7 – The Trusted Classic

Released in 2009, Windows 7 was a massive success. It fixed many of the issues of its predecessor, Windows Vista, and delivered a stable, fast, and user-friendly experience that is still fondly remembered by many.

Why You Might Love Staying on Windows 7

• Familiar and Simple: The primary appeal of Windows 7 is its straightforward and coherent design. The classic Start Menu, the clear taskbar, and the overall user interface are often praised as the peak of Microsoft’s user-friendly design, created at a time when the company had to deliver a high-quality product to win back users. For many, it just feels “right.” It is fast and responsive, especially on older hardware, because it is not weighed down by the advertisements, mandatory online accounts, and other features that some users consider “bloatware” in modern versions of Windows.
• Low Hardware Demands: Windows 7 is incredibly efficient and can run on computers that are ancient by today’s standards. The minimum requirements are just a 1 gigahertz (GHz) processor, 1 gigabyte (GB) of RAM, and 16 GB of hard drive space. This makes it a potential lifeline for older but still functional machines that simply cannot handle the demands of Windows 10 or 11.

The Big Reasons to Move On

• A Huge Security Risk: This is the single most important reason to stop using Windows 7. Using an analogy, running Windows 7 on the internet today is like living in a house where the company that made your locks has gone out of business. They no longer make new keys, and more importantly, they will never fix a lock if a burglar discovers a way to break it. Microsoft officially ended all support and stopped sending security updates for Windows 7 on January 14, 2020. This means that any new security hole discovered by hackers—and they are always looking—will remain open forever. Cybercriminals know this and actively search for Windows 7 machines to target with viruses, ransomware, and other attacks designed to steal personal information. The risk is so significant that national cybersecurity agencies, like the UK’s NCSC, have officially warned people not to use Windows 7 for sensitive tasks like online banking or accessing personal email. Continuing to use it for anything that involves personal data is a serious gamble.
• Modern Software is Leaving It Behind: The digital world has moved on from Windows 7. Companies that make new software and apps are no longer designing them to work on this old OS. Crucially, this includes the most important software for staying safe online. Most major antivirus companies are ending their support, and even the last major web browser to support it, Firefox, has set a final end date for updates. This means you will be stuck using old, outdated, and potentially insecure versions of the very programs you rely on to protect yourself and browse the web.

Chapter 1.2: Windows 10 – The Modern Standard

Windows 10, released in 2015, became the workhorse of the modern Windows era. It successfully blended the familiar feel of older versions with a host of new, modern features, establishing itself as a stable and reliable platform for hundreds of millions of users.

Why Windows 10 is a Great Place to Be

• The Best of Both Worlds: A key reason for Windows 10’s success was its ability to please users of both Windows 7 and the more touch-focused Windows 8. It brought back the beloved Start Menu from Windows 7 but enhanced it with modern “Live Tiles” that can show information at a glance. It also introduced useful new features like the Cortana digital assistant, the Action Center for notifications, and advanced multitasking tools. This balance made it feel both familiar and new. As a mature operating system, it is incredibly stable and runs the largest and most diverse library of software and games in the world, a key advantage for compatibility.
• Robust, Built-in Security: Windows 10 marked a major step up in built-in security. It includes Windows Security (formerly Windows Defender), a powerful and free antivirus, anti-malware, and firewall solution that is active by default. It provides real-time protection by scanning files and websites for threats without requiring any user intervention. Additional layers of security, like User Account Control (which warns you before a program makes changes) and Windows SmartScreen (which blocks potentially dangerous apps and downloads), work together to create a safe computing environment right out of the box.
• Flexible and Customizable: Windows 10 offers a good degree of personalization. Users can easily change the desktop background, system-wide accent colors, and the appearance of the lock screen. The Start Menu and taskbar can also be customized by pinning favorite apps, rearranging tiles, and choosing what icons appear. The OS was designed from the ground up to work equally well with a traditional mouse and keyboard as it does with touch-enabled devices like tablets and 2-in-1 laptops.

Thinking About a Change? The Clock is Ticking

• The 2025 Deadline: The single biggest reason to plan a move away from Windows 10 is its approaching “end-of-life.” Microsoft has officially announced that it will stop providing free security updates and technical support for Windows 10 after October 14, 2025. After this date, Windows 10 will be in the same vulnerable position that Windows 7 is in today, where new security flaws will no longer be fixed. While there will be a paid option for businesses to get extended security updates for a few more years, for the average home user has options to receive extended security updates for a year, the clock is ticking.
• The Hardware Hurdle: A major complication in this transition is that many computers that run Windows 10 perfectly well are not eligible for the free upgrade to Windows 11. This is due to Windows 11’s much stricter hardware requirements, which will be discussed in the next section. This situation is expected to create a massive number of “Windows refugees”—an estimated 240 million PCs—whose perfectly good hardware will be left without a secure, supported Microsoft OS. This forces users into a difficult choice: buy a brand-new computer just to run Windows 11, or explore alternative operating systems like Linux or ChromeOS that will happily run on their existing hardware.

Chapter 1.3: Windows 11 – The Newest Generation

Windows 11 represents Microsoft’s vision for the future of the PC. It introduces a significant visual redesign and new features focused on productivity, security, and modern work habits, including the integration of artificial intelligence directly into the desktop.

What’s New and Exciting in Windows 11

• A Fresh, Modern Look: The most immediate change in Windows 11 is its redesigned user interface. It features a centered Start menu and taskbar (though this can be moved back to the left), softly rounded corners for all windows, and new, subtle animations. The goal was to create a calmer, cleaner, and more modern aesthetic that helps users focus. This new look is an evolution of Microsoft’s “Fluent Design System” and is more consistent than the design of Windows 10.
• Productivity Power-Ups: Windows 11 introduces several powerful tools for multitasking. Snap Layouts allow a user to hover over a window’s maximize button and choose from several predefined arrangements to neatly organize multiple apps on the screen. When you create one of these layouts, Windows remembers it as a Snap Group, which you can easily minimize or restore from the taskbar. It also features improved support for using multiple monitors, remembering where your windows were placed when you disconnect and reconnect an external display.
• AI is Built-In: A headline feature of Windows 11 is the deep integration of Copilot, Microsoft’s AI assistant. Accessible directly from the taskbar, Copilot can help with a wide range of tasks. You can ask it to change system settings, summarize a long document, generate an image based on a description, or answer complex questions, all using natural language. This brings the power of AI directly into the user’s daily workflow.
• Gaming Enhancements: Windows 11 inherits and improves upon Windows 10’s gaming prowess. It includes technologies brought over from the Xbox Series X/S consoles, such as DirectStorage, which allows games to load assets much faster on computers with modern SSDs, and Auto HDR, which can automatically improve the color and brightness in many games, even if they weren’t originally designed for HDR displays.

Potential Hurdles and Downsides

• Strict Hardware Requirements: This is by far the biggest challenge for users wanting to upgrade. Windows 11 requires a relatively new computer that includes specific security hardware. The two main requirements are a Trusted Platform Module (TPM) version 2.0 and Secure Boot capability.
  • To explain this simply: TPM 2.0 is like a tiny, highly secure vault or a special security guard chip built into your computer’s main board. Its job is to protect sensitive information like encryption keys and passwords from being stolen by malware. Secure Boot is a feature that checks to make sure no malicious software has tried to sneak into the computer’s startup process. While these features make Windows 11 more secure, many perfectly capable computers, especially those made before 2018, do not have them and therefore cannot officially run Windows 11.
• A Divisive Design: While Microsoft aimed for a more modern and simplified look, not all users have been pleased with the changes. Some find the centered taskbar and the redesigned, more basic Start Menu to be less efficient and less customizable than the familiar layout of Windows 10. The removal of certain taskbar functionalities, in particular, has been a point of criticism.

The Evolving Landscape of Windows

The journey from Windows 7 to Windows 11 reveals a fundamental shift in how Microsoft views its operating system. The simplicity and user-centric control of Windows 7, born from a need to deliver a purely high-quality product, has gradually been replaced by a more complex, service-oriented model in Windows 10 and 11. Features like mandatory Microsoft accounts for setup, integrated advertising in the Start Menu, and the collection of system data (telemetry) are designed to create a connected ecosystem of services like OneDrive, Microsoft 365, and Copilot.

For many users, these integrations are a welcome convenience. For others, however, they are perceived as intrusive and a loss of control, leading them to describe modern Windows as “bloated” or even “user-hostile”. This perception creates a significant psychological barrier to upgrading. The decision to stay on an older OS like Windows 7, despite the severe security risks, is often not just a technical one but an emotional and philosophical one. It reflects a user’s desire for a computer that feels like a simple tool they own and control, rather than a gateway to a company’s ecosystem of services.

This tension has created a pivotal moment in the world of personal computing. The combination of Windows 10’s approaching end-of-life and Windows 11’s strict hardware requirements has produced the largest potential market for alternative operating systems in over a decade. Millions of users with fully functional hardware will soon need a new, secure OS. This has opened the door for competitors like Linux and ChromeOS, which are specifically designed to run well on this exact type of hardware, to present themselves as viable and attractive alternatives. Microsoft’s strategic push for a more secure hardware foundation has, perhaps unintentionally, given its rivals their greatest opportunity for growth.
