Windows 11 has stricter hardware requirements compared to previous Windows versions, which means not every PC that runs Windows 10 is eligible for an upgrade. Before attempting to install or upgrade, it is important to confirm whether your system meets Microsoft’s official requirements to avoid installation errors or unsupported configurations.
Compatibility depends on several key components such as the processor, TPM version, Secure Boot support, RAM, and storage. In many cases, a PC may appear powerful enough but still fail Windows 11 checks due to firmware or security feature settings that are disabled by default.
Checking if your PC can run Windows 11 involves using built-in Microsoft tools and verifying system specifications manually. The steps below explain all reliable methods to confirm Windows 11 compatibility.
How to Check If Your PC Can Run Windows 11
The methods in this section help you determine Windows 11 eligibility using official tools and system settings. Follow the steps in order for accurate results.
1. Use the PC Health Check Tool
Microsoft’s PC Health Check tool provides the quickest compatibility check.
- Download and install PC Health Check from Microsoft’s official website.
- Open the app after installation.
- Click Check now under the Windows 11 section.
- Review the compatibility result displayed.
The tool clearly states whether your PC meets Windows 11 requirements and highlights unsupported components.
2. Check CPU Compatibility Manually
Windows 11 supports only specific processors.
- Press Windows + R, type msinfo32, and press Enter.
- Check the Processor entry.
- Compare the processor model with Microsoft’s supported CPU list.
If the CPU is not on the supported list, Windows 11 will not be officially supported.
3. Verify TPM Version
TPM 2.0 is a mandatory requirement.
- Press Windows + R, type tpm.msc, and press Enter.
- Check TPM Manufacturer Information.
- Confirm the Specification Version shows 2.0.
If TPM is present but disabled, it may need to be enabled in BIOS or UEFI settings.
4. Check Secure Boot Support
Secure Boot must be supported and enabled.
- Press Windows + R, type msinfo32, and press Enter.
- Look for Secure Boot State.
- Confirm it shows On.
If Secure Boot is supported but disabled, it can usually be enabled in firmware settings.
5. Confirm RAM and Storage Requirements
Windows 11 requires minimum system memory and storage.
- Open Settings.
- Go to System > About.
- Check Installed RAM is at least 4 GB.
- Confirm available storage is 64 GB or more.
Insufficient RAM or storage will block installation.
6. Check System Type and Architecture
Only 64-bit systems are supported.
- Open Settings.
- Go to System > About.
- Check System type.
- Confirm it shows 64-bit operating system.
32-bit systems are not compatible with Windows 11.
7. Verify Graphics and Display Requirements
Basic graphics requirements must be met.
- Ensure the GPU supports DirectX 12.
- Confirm the display resolution is at least 720p.
- Check the display size is 9 inches or larger.
Most modern systems meet these requirements automatically.
8. Check BIOS or UEFI Mode
Windows 11 requires UEFI firmware.
- Press Windows + R, type msinfo32, and press Enter.
- Look for BIOS Mode.
- Confirm it shows UEFI.
Legacy BIOS systems must be converted to UEFI for compatibility.
Final Thoughts
Checking if your PC can run Windows 11 before upgrading helps prevent installation failures and unsupported system setups. Using the PC Health Check tool alongside manual verification ensures accurate compatibility results.
