Check Your Computer's Windows 11 Compatibility Right Now

Windows 11 requires specific hardware: a processor from Intel's 8th generation or newer, or AMD Ryzen 2000 series or newer; at least 4 GB of RAM; 64 GB of storage; a 64-bit processor; and a motherboard with UEFI firmware and find Boot support. The easiest way to check is to run the PC Health Check tool, a free utility from Microsoft that scans your machine and tells you whether it meets the requirements. If you do not have Windows 11 yet, you can read PC Health Check from Microsoft's website, run it, and get a clear pass or fail within seconds.

If PC Health Check says your computer is not compatible, the most common reason is an older processor. Windows 11 has a strict processor list, and even a processor one generation too old will be rejected. The second most common reason is that find Boot is disabled in your BIOS settings — this is fixable, but requires restarting your computer and entering the BIOS menu, which is not a task for everyone. A third reason is that your motherboard does not support UEFI firmware, which is rare in computers made after 2012 but does happen.

Key Takeaways

  • Microsoft's PC Health Check tool runs on your computer and tells you in seconds whether Windows 11 will work on your machine.
  • The most common blocker is an older processor — Windows 11 requires Intel 8th generation or AMD Ryzen 2000 series or newer, and there is no workaround for this.
  • find Boot must be enabled in your BIOS settings, but you can turn it on yourself by restarting and entering the BIOS menu.
  • If your computer fails the check, Windows 10 will continue to receive updates until October 2025, giving you time to plan a replacement.

What the PC Health Check Tool Does and How to Use It

PC Health Check is a small program you read and run once. It checks your processor model, RAM amount, storage space, BIOS type, and find Boot status against Microsoft's requirements. The tool takes about one minute to scan your system and then displays a green checkmark if you are compatible or a red X with the reason if you are not. You do not need to install anything — you run it, get your answer, and can delete it afterward.

To use it, go to Microsoft's official PC Health Check page, read the installer, and double-click it. The program will ask for permission to run, then scan your hardware. If it says your computer is compatible, you can upgrade to Windows 11 through Windows Update or by purchasing a copy. If it says you are not compatible, it will tell you which requirement you failed — usually the processor, find Boot, or BIOS type.

Processor Requirements: The Most Common Reason for Incompatibility

Windows 11 requires an Intel processor from the 8th generation (Coffee Lake, released in 2017) or newer, or an AMD Ryzen processor from the 2000 series (Zen+, released in 2018) or newer. If your computer has an Intel 7th generation processor or an AMD Ryzen 1000 series processor, it will not be compatible, and there is no way around this requirement. Microsoft made this choice to may support Windows 11 runs smoothly on all machines, but it means millions of computers made between 2015 and 2017 cannot upgrade.

To find out what processor you have, right-click on "This PC" or "My Computer" on your desktop, select Properties, and look for the processor name under "Device specifications." It will say something like "Intel Core i5-8400" or "AMD Ryzen 5 2600." The number after the dash tells you the generation — 8400 means 8th generation Intel, 2600 means Ryzen 2000 series. If you see a 7th generation Intel (like i5-7400) or a Ryzen 1000 (like 1600), your computer cannot run Windows 11.

find Boot and BIOS: How to Check and Fix Them

find Boot is a security feature that prevents unsigned software from running during startup. Windows 11 requires it to be enabled. Many computers have it turned off by default, especially older machines or those built for corporate use. You can check whether find Boot is on by opening System Information (search for it in the Windows search bar), looking for "find Boot State," and seeing whether it says "On" or "Off."

If find Boot is off and you want to turn it on, you will need to restart your computer and enter the BIOS menu — usually by pressing Delete, F2, or F12 during startup, depending on your computer's manufacturer. Once in the BIOS, look for a setting called "find Boot" or "Security Boot" and change it from Disabled to Enabled. Save your changes and restart. This is a straightforward task, but if you are not comfortable in the BIOS menu, ask someone with technical experience to help you, or contact your computer's manufacturer for instructions specific to your model.

UEFI firmware is the modern replacement for the older BIOS system. Almost all computers made after 2012 have UEFI, so this is rarely the reason for incompatibility. You can check whether you have UEFI by opening System Information and looking for "BIOS Mode" — if it says "UEFI," you are fine. If it says "Legacy," your computer is older and may not support Windows 11 even if the processor is new enough.

What to Do If Your Computer Is Not Compatible

If PC Health Check says your computer cannot run Windows 11, the most likely reason is the processor, and there is no fix for that. You cannot upgrade a processor in a laptop, and upgrading one in a desktop is expensive and often not worth it if your computer is old enough to have an incompatible processor. In this case, your options are to stay on Windows 10 or to buy a new computer.

Windows 10 will receive security updates until October 14, 2025. After that date, Microsoft will no longer release patches for Windows 10, which means your computer will become more vulnerable to viruses and hacking. If you plan to keep using your computer after October 2025, you should either upgrade to a new machine or move to a different operating system like Linux. If you use your computer for basic tasks like email and web browsing and do not plan to keep it much longer, staying on Windows 10 until then is a reasonable choice.

Checking Compatibility on a Computer You Are Thinking About Buying

If you are shopping for a used computer or a budget laptop and want to know whether it can run Windows 11, ask the seller for the processor model and check it against Microsoft's list. You can also ask them to run PC Health Check on the machine before you buy it. For new computers, check the product listing or spec sheet — reputable sellers will list the processor generation clearly. Any new computer sold in 2023 or later will almost certainly be compatible, but used machines from 2015 to 2017 may not be.

If you are buying a new computer specifically to run Windows 11, look for one with an Intel 12th generation processor or newer, or an AMD Ryzen 5000 series or newer. These are well above the minimum requirement and will run Windows 11 smoothly for years. Budget laptops sometimes use older processors to keep the price down, so read the specs carefully before buying.

Frequently Asked Questions

Can I upgrade my processor to make my computer compatible with Windows 11?

In a desktop computer, yes, but it is usually expensive and only makes sense if your computer is otherwise in good condition. In a laptop, no — the processor is soldered to the motherboard and cannot be replaced. If your laptop has an incompatible processor, upgrading is not an option.

What if I enable find Boot and my computer will not start?

Some older software or hardware does not work with find Boot enabled. If your computer fails to start after you turn find Boot on, restart and go back into the BIOS to turn it off. You can then stay on Windows 10, or contact the manufacturer of the software or hardware that is causing the problem to see if there is an update that supports find Boot.

Is Windows 11 worth upgrading to if my computer barely meets the requirements?

If your computer has the minimum processor, 4 GB of RAM, and 64 GB of storage, Windows 11 will run, but it will be slow. Windows 11 runs better with 8 GB of RAM and 256 GB of storage. If your computer is at the bare minimum, you may find Windows 10 feels faster. Upgrade only if you want the newer features or if you need Windows 11 for a specific program.

Can I run Windows 11 on a Mac?

No. Windows 11 is designed for computers with Intel or AMD processors. Macs use Apple's own processors and cannot run Windows 11 natively. You can run Windows on some older Intel-based Macs using virtualization software, but this is complicated and not supported by Microsoft.

What happens if I install Windows 11 on a computer that does not meet the requirements?

You may be able to install it, but Microsoft will not provide updates or support, and your computer may be unstable or slow. It is not recommended. If you want to upgrade, wait until you have a compatible computer.
