How to check if processor is arm64 or x64 (64-bit) on Windows 11

• To check whether a Windows 11 PC is x64 or arm64, open Settings > System > About and look under “System type.” It’ll say either “64-bit operating system, x64-based processor” or “64-bit operating system, ARM-based processor.”
• Alternatively, open System Information (msinfo32) or run in Command Prompt systeminfo | findstr /C:"System Type" to get the same result.

On Windows 11, you have at least two ways to check if the computer’s processor is x64 or ARM64, and in this guide, you will learn how. 

Although both processor system types support a 64-bit architecture for running Windows 11 and applications, only the “x64” architecture offers the most compatibility with traditional desktop programs. You will find this architecture on common processors from Intel and AMD.

On the other hand, the “ARM64” architecture is found on ARM processors (typically from Qualcomm). While this architecture is popular among mobile devices, it’s still relatively new for Windows devices, and if you have an ARM64-based computer, you won’t be able to install most traditional applications.

If you want to determine whether your computer has an x64 or ARM64 processor on Windows 11, you can find this information in at least three ways using the Settings app, System Information, or Command Prompt.

This guide will teach you how to check whether your Windows 11 computer is x64- or ARM64-based.

Check if processor is x64 or ARM64 on Windows 11

To determine whether you have an x64 or ARM64-based device on Windows 11, use these steps:

1. Open Settings on Windows 11.

2. Click on System.

3. Click the About page.

4. Check the “System type” information under the “Device info” section. If it reads “64-bit operating system, x64-based processor,” you have a 64-bit processor. If it reads “64-bit operating system, ARM-based processor,” then you have an ARM64-based processor.

   

Once you complete the steps, the About page will display whether the computer has an ARM64 or x64 (64-bit) processor.

Check if processor is x64 or ARM64 from System Information

To check if your computer is an x64 or ARM64 device with System Information, use these steps: 

1. Open Start.

2. Search for System Information and click the top result to open the app.

3. Click on Summary from the left pane.

4. Check the “System Type” information. If it reads “x64-based PC,” you have a 64-bit processor. If it reads “ARM-based PC” then you have an ARM64-based processor.

   

After you complete the steps, the System Information Summary page will display the details of the processor system type.

Check if processor is x64 or ARM64 from Command Prompt

To find out if you have an x64 or ARM64-based computer with Command Prompt, use these steps:

1. Open Start.

2. Search for Command Prompt and click the top result to open the app.

3. Type the following command to check the computer’s architecture and press Enter:

   systeminfo | findstr /C:"System Type"

   

4. Check the “System Type” information. If it reads “x64-based PC,” you have a 64-bit processor. If it reads “ARM-based PC” then you have an ARM64-based processor.

Once you complete the steps, you will know whether the system processor type is available on your computer.

I’m not mentioning x86 in this guide because Windows 11 no longer supports the 32-bit processor architecture.

Pureinfotech’s Take

I still think a lot of people underestimate how important it is to know whether their computer is running an x64 or ARM64 processor. A lot of users don’t care until they try installing an app, a driver, or even a game that suddenly doesn’t work as expected. That’s usually when the architecture question becomes relevant.

In my experience, this matters even more now because Microsoft keeps pushing Windows on ARM devices harder every year. Qualcomm-powered laptops have improved significantly, but compatibility remains the biggest concern. If you rely on older desktop apps, custom utilities, or certain drivers, an x64 system is still the safer choice for most people.

I also like that Windows 11 makes this information easy to find in multiple places. The Settings app is probably enough for everyday users, while Command Prompt and System Information remain useful for troubleshooting or verifying hardware details remotely.

And yes, leaving x86 out of the guide makes sense. Windows 11 has moved on from 32-bit processors, and realistically, most users shouldn’t be investing time in that platform anymore.

What are your thoughts about ARM64 and x64 support on Windows 11? Let me know in the comments.
