Windows 11 Compatibility Checker
Use this Windows 11 Compatibility Checker to compare a PC against the official Microsoft minimum requirements before you upgrade, reinstall, or buy second-hand hardware. Enter the processor status, core count, RAM, storage, TPM, Secure Boot, graphics, display, and setup readiness to get a clear pass, review, or fail result. The checker is based on Microsoft requirements, but it is not an automatic hardware scan; it only evaluates the values you enter.
How the compatibility check works
-
1
Enter the hardware basics
Add the CPU support status, clock speed, core count, 64-bit support, RAM, and available storage.
-
2
Confirm firmware security
Choose the TPM version and whether the PC is UEFI Secure Boot capable or only needs Secure Boot enabled.
-
3
Check graphics, display, and setup
Add DirectX/WDDM readiness, screen size, vertical resolution, and whether internet setup is available.

Read the verdict
Hard requirement misses are marked as failures, while unknown or disabled-but-fixable items are marked for review.
Windows 11 minimum requirements used here
Microsoft lists the baseline for Windows 11 as a compatible 64-bit processor or SoC running at 1 GHz or faster with 2 or more cores, 4 GB of RAM, 64 GB of storage, UEFI Secure Boot capability, TPM 2.0, DirectX 12 compatible graphics with a WDDM 2.0 driver, and a display larger than 9 inches with HD 720p resolution and 8 bits per color channel. Windows 11 Home and Windows 11 Pro for personal use also need internet connectivity and a Microsoft account during initial setup.

This checker treats missing hardware requirements as a fail. It treats uncertain items, such as an unknown CPU list status or a Secure Boot setting that may simply be disabled in firmware, as review items. Installing Windows 11 on a device that does not meet the requirements is unsupported and not recommended.
Worked example
Suppose a laptop has an Intel processor that appears on Microsoft’s supported list, runs at 2.4 GHz, has 4 cores, supports 64-bit instructions, includes 8 GB RAM, a 256 GB SSD, TPM 2.0, UEFI Secure Boot, DirectX 12 graphics with WDDM 2.0, a 13.3-inch 1080p display, and internet access for setup. Every hard requirement passes, so the tool returns a pass result.
If the same laptop has TPM 1.2 instead of TPM 2.0, the verdict changes to fail because TPM 2.0 is a hard Windows 11 requirement. If Secure Boot is available but disabled, the verdict becomes review because the PC may meet the requirement after a firmware setting change.
Requirement table
| Area | Windows 11 minimum | Checker behavior |
|---|---|---|
| Processor | 1 GHz, 2+ cores, 64-bit, supported model | Fail if speed, cores, 64-bit, or support is missing; review if model status is unknown |
| Memory | 4 GB RAM | Fail below 4 GB |
| Storage | 64 GB or larger storage device | Fail below 64 GB |
| Firmware | UEFI Secure Boot capable | Fail if not capable; review if disabled or unknown |
| Security | TPM 2.0 | Fail for TPM 1.2 or none; review if unknown |
| Graphics | DirectX 12 or later with WDDM 2.0 | Fail if not compatible; review if unknown |
| Display | Larger than 9 inches, HD 720p or higher, 8 bits per color channel | Fail at 9 inches or smaller, or below 720p height |
| Setup | Internet and Microsoft account for Home and personal Pro setup | Review if not ready |
What this checker cannot do
The checker does not scan your device, query your BIOS, read your processor model, or validate Microsoft’s live supported CPU lists. Use Windows Settings, System Information, Device Manager, or the PC manufacturer’s firmware screen to find the values, then enter them here. For processor list confirmation, compare your exact CPU model with Microsoft’s supported processor documentation.
Frequently Asked Questions
No. It is a manual compatibility checklist. The values you type or select can be sent to this site through Livewire and funnel URLs so the page can calculate and preserve your settings; it does not inspect your hardware automatically.
Windows 11 requires not only a 64-bit, 1 GHz, 2-core processor, but also a CPU model on Microsoft’s supported processor list. If you do not know the model-list status, the hardware might be fine, but it needs confirmation.
Not always. Some PCs are UEFI Secure Boot capable but have the setting disabled. That is why the checker marks disabled Secure Boot for review instead of treating it like a hard hardware failure.
Microsoft says installing Windows 11 on devices that do not meet the minimum requirements is unsupported and not recommended. This checker does not provide bypass instructions or suggest that unsupported installs are safe.
