Upgrading to the latest operating system can bring enhanced performance, security, and features. But before making the switch, the most important question to ask is: How can I check if my PC is compatible with Windows 11? In this guide, we’ll walk you through all the steps—both automatic and manual—to determine if your current PC meets the system requirements for Windows 11.
Why Compatibility Matters for Windows 11

Windows 11 introduces a range of new features like Snap Layouts, DirectStorage, and better virtual desktop support. However, it also comes with strict system requirements to ensure optimal performance and security. Microsoft has implemented hardware-based requirements like TPM 2.0 and Secure Boot, which many older systems may not support.
That’s why checking compatibility before you install Windows 11 is crucial.
Method 1: Use Microsoft’s PC Health Check Tool
The easiest and most reliable way to check compatibility is to use Microsoft’s PC Health Check app. Here’s how to use it:
- Download the Tool
Visit the official Microsoft site and download the PC Health Check Tool. - Install and Launch
Install the tool on your system and open it. - Click “Check Now”
The tool will quickly scan your system and let you know whether your PC can run Windows 11. If not, it will highlight the components that don’t meet the requirements.
This tool provides a simple summary, making it perfect for non-tech users.
Method 2: Use WhyNotWin11 for Advanced Analysis
If you want a more detailed report, you can use WhyNotWin11, a free open-source tool:
- Download it from the official GitHub page.
- Run the executable file (no installation needed).
- You’ll get a detailed compatibility checklist including TPM version, CPU support, Secure Boot, and more.
Note: Be cautious when downloading from unofficial sites. Always verify the source.
Method 3: Manually Check System Requirements
If you prefer not to use tools, you can manually verify the Windows 11 system requirements:
1. Processor
- Minimum: 1 GHz or faster with 2 or more cores on a compatible 64-bit processor.
- Check by right-clicking This PC > Properties and viewing CPU info.
2. RAM
- Minimum: 4 GB.
- Check in Task Manager > Performance > Memory.
3. Storage
- Minimum: 64 GB.
- Go to Settings > System > Storage.
4. System Firmware
- Must support UEFI and Secure Boot.
- Check in System Information > BIOS Mode and look for “UEFI”.
5. TPM Version
- Minimum: TPM 2.0.
- Press Windows + R, type
tpm.msc
, and check the version.
6. Graphics Card
- Compatible with DirectX 12 or later with WDDM 2.0 driver.
7. Display
- At least 9” with HD resolution (720p).
If any of these components don’t meet the requirement, you may need to upgrade your hardware.
What to Do If Your PC Isn’t Compatible

If your PC doesn’t meet the requirements:
- Upgrade the hardware (e.g., enable TPM in BIOS or install a supported CPU).
- Stay on Windows 10, which will be supported until October 14, 2025.
- Buy a new device that comes pre-installed with Windows 11.
Final Thoughts
Now that you know how to check if your PC is compatible with Windows 11, you’re ready to make an informed decision. Whether you use Microsoft’s tool or check everything manually, ensuring your system meets the requirements will lead to a smooth and secure upgrade experience.
Keep in mind that running Windows 11 on unsupported hardware might work temporarily, but could lead to performance or security issues.
