How to Instantly Check Windows 11 Compatibility

Key Takeaways:

  • Use the official Microsoft PC Health Check app to quickly assess your PC’s compatibility with Windows 11
  • Ensure your PC meets the minimum system requirements for Windows 11, including a compatible 64-bit processor, 4GB RAM, 64GB storage, UEFI secure boot, TPM 2.0, and DirectX 12 compatible graphics
  • If the PC Health Check app and Windows Update provide conflicting results, try alternative methods like the WhyNotWin11 tool or manual compatibility checks

As a technology journalist with over a decade of experience covering Microsoft operating systems, I’ve closely followed the development and release of Windows 11. One of the most common questions I receive from readers is how to quickly determine if their current PC is compatible with Microsoft’s latest operating system. In this article, I’ll guide you through the process of instantly checking your Windows 11 compatibility using a few simple methods.

Using the Microsoft PC Health Check App

The easiest and most reliable way to check your PC’s compatibility with Windows 11 is to use Microsoft’s official PC Health Check application. To get started, follow these steps:

  1. Download the PC Health Check app from the official Microsoft website (
  2. Install the application and launch it
  3. Click on the “Check now” button under the “Introducing Windows 11” section

The PC Health Check app will quickly analyze your system and provide a clear result indicating whether your PC meets the minimum system requirements for Windows 11. If your PC is compatible, you’ll see a message stating, “This PC can run Windows 11.” If your PC does not meet the requirements, the app will provide details on which components are not compatible, such as the processor, RAM, or TPM version.

Minimum System Requirements for Windows 11

To better understand your PC’s compatibility with Windows 11, it’s essential to know the minimum system requirements set by Microsoft:

  • Processor: 1 GHz or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC)
  • Memory: 4 GB RAM
  • Storage: 64 GB or larger storage device
  • System firmware: UEFI, Secure Boot capable
  • TPM: Trusted Platform Module (TPM) version 2.0
  • Graphics card: DirectX 12 compatible graphics / WDDM 2.x
  • Display: >9″ with HD Resolution (720p)
  • Internet connection: Microsoft account and internet connectivity required for setup for Windows 11 Home

If your PC meets or exceeds these requirements, it should be compatible with Windows 11. However, some users have reported inconsistencies between the PC Health Check app results and the compatibility information provided by the Windows Update tool.

Resolving Conflicting Compatibility Results

If the PC Health Check app indicates that your PC is compatible with Windows 11, but the Windows Update tool states otherwise, you can try the following methods to resolve the conflict:

  1. Use the WhyNotWin11 tool: This third-party, open-source tool provides a more detailed compatibility analysis than the PC Health Check app. It can help identify specific components that may be causing compatibility issues.
  2. Check compatibility manually: Review the minimum system requirements listed above and compare them to your PC’s specifications. Pay close attention to the processor, RAM, storage, and TPM requirements.
  3. Update your PC’s firmware: Ensure that your PC’s BIOS or UEFI firmware is up to date. Compatibility issues may arise if your firmware is outdated or if certain features like TPM or Secure Boot are not enabled.
  4. Install Windows 11 manually: If you are confident that your PC meets the minimum requirements, you can try installing Windows 11 manually using the Installation Assistant or by creating a bootable USB drive with the Windows 11 Media Creation Tool.


Checking your PC’s compatibility with Windows 11 is a straightforward process thanks to Microsoft’s PC Health Check app. By ensuring that your PC meets the minimum system requirements and resolving any potential conflicts between compatibility tools, you can confidently upgrade to Windows 11 and enjoy its new features and improvements. Remember to backup your data before proceeding with the upgrade, and don’t hesitate to seek further assistance if you encounter any issues during the process.
