Windows Operating Systems: Which one to choose in 2026?

Which Windows operating system to choose in 2026?

The question has never been more strategic. Between end of support, security updates, hardware requirements like TPM, new latest-generation Intel Core chips, integration of artificial intelligence with Copilot, and rapid evolution of professional and gaming uses, choosing a Windows version becomes a real technological turning point. A wrong choice can expose your computer to vulnerabilities, limit performance, or make certain software and applications incompatible.

Microsoft is accelerating the pace: regular updates, reinforced security patches, new cloud functionalities, DirectStorage, Auto HDR, Snap Windows, virtual desktop, widgets, rounded Start menu, and an interface designed for daily productivity. But not all machines are compatible, and some alternatives like Linux can become relevant depending on the use, cost, and level of control desired. Individual, business, IT fleet, gaming, or simple internet use, this guide helps you prepare for 2026, check your hardware, understand the advantages and disadvantages, and make a performing, secure, and durable choice.

Overview of different Windows versions

Windows 7: the still-loved veteran

Released in 2009, Windows 7 was long the preferred version for users, with over 630 million active users at its peak. Light, fluid, stable, it marked a generation.

But in 2026, Windows 7 no longer receives security updates. It therefore becomes a risky choice, especially for connected use. It can still be suitable for certain specific environments, but for the majority, it's time to upgrade to a more recent version.

Windows 8 and 8.1: a mixed experience

Launched in 2012, Windows 8 aimed for innovation with a completely redesigned, touch-oriented interface. Unfortunately, the result was not convincing. At its peak, it only reached 12% market share.

Even with Windows 8.1, correction attempts were not enough to convince. In 2026, this version is considered outdated and not very ergonomic. To be avoided for daily use.

Windows 10: the versatile choice

Since its launch in 2015, Windows 10 has established itself as a perfect compromise between performance, compatibility, and reliability. In 2026, it is still used by over 65% of Windows users worldwide.

It benefits from regular updates, a familiar interface, and excellent compatibility with software and peripherals. Windows 10 is still a very good choice today, especially for those who want to avoid the stricter hardware requirements of Windows 11.

Windows 11: the future-oriented system

Released in 2021, Windows 11 is the latest version of Microsoft's operating system. New design, improved features, enhanced productivity, and increased security: it's the natural choice for users looking for modernity.

In 2026, Windows 11 is ideal if you have a recent PC (compatible with TPM 2.0 in particular). It offers a fluid and pleasant user experience, designed to last.

Comparison of operating systems: Windows versus Mac and Linux

macOS: an elegant but closed system

Apple's operating system seduces with its design and fluidity. It works perfectly with Apple devices and is popular in creative circles (graphics, video editing, etc.).

But macOS remains a closed system. It is less compatible with many software, especially games, and requires the purchase of often expensive hardware.

Linux: freedom with its limits

Linux is a free and open-source operating system, ultra-flexible, popular with developers and enthusiasts. It offers great customization and good performance, even on old computers.

But for the average user, Linux can be complex to get started with. Many market software are not available on Linux, which can limit its adoption.

Windows: a balance between compatibility and simplicity

In 2026, Windows remains the most used operating system in the world, with over 70% market share. Why? Because it offers an excellent balance between accessibility, compatibility, and performance.

Whether for work, games, professional software, or office automation, Windows is there. And thanks to DA Licences, you can get an official Windows license at a low price, quickly and securely.

Guide on how to know the current version of Windows

Don't know which version of Windows you're using? No worries! There's a simple and quick way to check. Here are the steps to find out your current version of Windows in a few clicks:

1. Open the "Start" menu: Click the Start button in the lower-left corner of your screen.

2. Access settings: Type "Settings" in the search bar and open the corresponding application.

3. Go to "System": In the settings window, click on "System".

4. Check version information: Scroll down and click on "About". You will find information about the version of Windows installed on your device, including the version and build number.

If you are on Windows 10 or Windows 11, you will also see if recent updates have been installed. This can be useful to know if you are up to date in terms of security and features.

Consequences of operating system obsolescence

Each version of Windows has a limited lifespan. In 2026, several older versions like Windows 7 or Windows 8 are now obsolete, which can have significant consequences for users.

1. Security risks

When Windows reaches its end of life, Microsoft stops providing security updates. This means that vulnerabilities and security flaws will no longer be corrected, exposing your computer to attacks from cybercriminals. Without protection, your personal data, bank information, and files can be at the mercy of malware or ransomware.

2. Incompatibility with new software

As new software and applications are released, they are often optimized for recent versions of Windows. If you use an obsolete version like Windows 7, you risk experiencing compatibility issues with some modern programs. Certain productivity software, video games, or professional tools might simply refuse to run.

3. Lack of technical support

Another major drawback of operating system obsolescence is the end of technical support from Microsoft. If you encounter a technical problem, it will be much more difficult to find solutions, as the community and forums will likely no longer provide answers adapted to older versions of Windows.

4. Reduced performance

Older versions of Windows are also less optimized for recent PCs. If you use Windows 7 or Windows 8, you risk experiencing performance issues on modern machines, which are designed to leverage the capabilities of recent versions like Windows 10 and Windows 11.

5. Loss of new features

Regular updates to Windows 10 and Windows 11 bring innovative features: improved productivity, new security tools, and a redesigned interface. If you stick with an obsolete version, you deprive yourself of these new features. You also miss out on the necessary adjustments to make your experience more fluid and enjoyable.

How do I update my Windows operating system?

4. Restart your PCOnce the updates are installed, you may need to restart your computer to finalize the operation.
