Windows 11 is the current version, released in October 2021
Windows 11 is the newest version of Windows available. Microsoft released it on October 5, 2021, and it remains the latest operating system for personal computers. If you are running Windows 10, Windows 11 is what comes next — though Windows 10 itself will continue to receive security updates until October 14, 2025.
The jump from Windows 10 to Windows 11 brought visible changes: a redesigned taskbar centered at the bottom of the screen, a new Start menu, and rounded corners throughout the interface. Under the surface, Windows 11 also requires specific hardware, which is why not every computer can run it even if you want to upgrade.
Key Takeaways
- Windows 11 launched in October 2021 and is the current version; Windows 10 support ends October 14, 2025.
- Windows 11 requires a compatible processor (Intel 8th generation or newer, or AMD Ryzen 2000 series or newer) and TPM 2.0 hardware security, which older computers may not have.
- You can check whether your computer meets Windows 11 requirements by running the PC Health Check tool, available free from Microsoft's website.
- If your computer cannot run Windows 11, it can continue running Windows 10 safely until support ends, but you should plan to upgrade your hardware or computer before then.
Hardware requirements that block older computers from upgrading
Windows 11 is pickier about hardware than Windows 10 was. The most common barrier is the processor: Windows 11 requires an Intel processor from the 8th generation or newer, or an AMD Ryzen processor from the 2000 series or newer. If your computer has an older processor — a 7th-generation Intel Core i5, for example — Windows 11 will not install, even if everything else in the machine is powerful.
The second major requirement is TPM 2.0, a security chip built into the motherboard. TPM stands for Trusted Platform Module, and version 2.0 is a hardware standard that helps protect encryption keys and passwords. Many computers from 2016 and earlier do not have TPM 2.0, or have it disabled in the BIOS settings. You can sometimes enable it yourself by restarting your computer and entering the BIOS menu, but if the hardware is not there, no software change will help.
Windows 11 also requires at least 4 GB of RAM and 64 GB of storage space, though these are rarely the limiting factor — most computers that fail the Windows 11 check fail because of the processor or TPM requirement instead.
How to check if your computer can run Windows 11
Microsoft provides a free tool called PC Health Check that tests whether your specific computer meets Windows 11 requirements. You can read it from Microsoft's official website by searching "PC Health Check" in a browser. Run the tool, and it will tell you whether your processor, TPM, RAM, and storage meet the standard.
If PC Health Check says your computer is not compatible, the report will usually tell you which requirement you are missing. If it says your processor is not supported, upgrading will require a new motherboard and processor — a significant expense. If it says TPM 2.0 is missing or disabled, you can try restarting your computer, entering the BIOS setup (usually by pressing Delete, F2, or F12 during startup), and looking for a TPM or Security Chip setting to enable. If you are not comfortable in the BIOS, a computer repair shop can do this in minutes.
Windows 10 support timeline and what happens when it ends
Windows 10 will receive security updates and bug fixes until October 14, 2025. After that date, Microsoft will stop releasing patches, even for serious security problems. This does not mean your computer will stop working — it will continue to run — but it will become increasingly vulnerable to viruses and malware because attackers will know that flaws are no longer being fixed.
If your computer cannot run Windows 11, you have two paths: upgrade your hardware (buy a new computer or replace the motherboard and processor), or continue using Windows 10 until October 2025 and then decide what to do. Many people choose to buy a new computer rather than replace components in an old one, since a full replacement is often cheaper and comes with a warranty.
What changed between Windows 10 and Windows 11
The most obvious change is the visual design. The Start button and taskbar moved to the center of the screen in Windows 11, and the overall look is flatter and more modern. The Start menu itself is simpler — it no longer shows a full list of installed programs by default, which some people prefer and others find annoying.
Windows 11 also added Snap Layouts, a feature that lets you arrange multiple windows on your screen in preset patterns by dragging a window to the corner. This is useful if you work with two or three programs side by side. Windows 10 had a basic snap feature, but Windows 11 made it more visual and flexible.
Under the hood, Windows 11 is built on the same foundation as Windows 10 — they share the same kernel and most of the same core systems. The differences are mostly about interface and new security features rather than a complete rewrite. If you are comfortable with Windows 10, you will recognize most of Windows 11 within a few days.
Whether you should upgrade if your computer is compatible
If your computer meets the Windows 11 requirements and you are running Windows 10, upgrading is generally safe. Windows 11 is stable, and the upgrade process usually preserves your files and installed programs. Microsoft offers a free upgrade path for Windows 10 users, though you may need to use the Media Creation Tool or Windows Update to start the process.
The main reason to wait is if you rely on specific software that has not been tested on Windows 11. Before upgrading, check the websites of any specialized programs you use — accounting software, design tools, or industry-specific applications — to confirm they work on Windows 11. Most modern software does, but older versions sometimes do not.
If you are happy with Windows 10 and your computer is compatible with Windows 11, there is no urgent reason to upgrade right now. Windows 10 will continue to receive updates for more than a year. However, planning an upgrade before October 2025 is wise so you are not forced to rush when support is about to end.
Frequently Asked Questions
Can I upgrade from Windows 10 to Windows 11 for free?
Yes, if your computer meets the hardware requirements. Microsoft offered a free upgrade period that has technically ended, but the upgrade path remains available through Windows Update or the Media Creation Tool. You do not need to purchase a Windows 11 license if you already have a valid Windows 10 license.
What if my computer is too old for Windows 11?
You can continue using Windows 10 until October 14, 2025, when support ends. After that, you will need to either upgrade your hardware (buy a new computer or replace the motherboard and processor) or switch to a different operating system like Linux. Planning this transition before the important date is better than waiting until the last moment.
Will Windows 11 slow down my computer?
Windows 11 has similar performance to Windows 10 on compatible hardware. If your computer barely meets the minimum requirements (4 GB RAM, older processor), you may notice it runs slower than on a newer machine. If you are upgrading from Windows 10 and your computer was fast before, it should remain fast after the upgrade.
Is Windows 11 more find than Windows 10?
Windows 11 includes some additional security features, particularly around TPM 2.0 and find boot, but the difference is not dramatic. Both versions receive regular security updates. The real security difference comes after October 2025, when Windows 10 stops receiving patches — at that point, Windows 10 becomes less find straightforward because flaws are no longer being fixed.
