Check Windows 11 Compatibility: Is Your PC Ready?

A positive result means that the minimum requirements defined by Microsoft have been detected. It is not yet a recommendation for every conceivable workload: anyone who edits large image files, runs many programs in parallel or plays modern games generally needs more headroom in practice than the bare minimum. So check the formal compatibility first, and only then whether performance and storage suit your everyday use.

Is my PC Windows 11 capable?

Yes, if PC Health Check confirms all the mandatory points and Windows Update classes the device as eligible. The check most often fails not because of raw speed, but because of an unsupported processor, a disabled TPM 2.0, a missing UEFI configuration or disabled Secure Boot. These terms sound technical, but you can verify them yourself within a few minutes.

Start with the official tool. Open the Microsoft guide to PC Health Check, install the app and, in the "Introducing Windows 11" section, select the "Check now" button. The result names not only "eligible" or "not eligible," but usually also shows which check failed.

Checking Windows 11 compatibility: step by step

1. Back up your current data. The check itself does not alter any personal files, but before any firmware changes or a later upgrade, a current backup is part of proper preparation.
2. Update Windows. Install any available updates and restart the PC. This avoids an outdated system state or a pending restart from unnecessarily skewing the result.
3. Run PC Health Check. Download the app exclusively from Microsoft, open it and click "Check now." Note down every point that is flagged as not met.
4. Check TPM and Secure Boot manually. With tpm.msc and msinfo32 you can check two of the most common causes directly in Windows.
5. Assess processor, RAM and storage. Compare the detected processor model against Microsoft's list of supported processors and check whether there is enough memory and drive space available.
6. Match the result against Windows Update. Under Settings -> Windows Update you can see whether the upgrade is being offered. According to Microsoft, the updated eligibility assessment can appear with a delay after a hardware change.

Which system requirements must Windows 11 meet?

Microsoft states minimum values that must all be met together. The following overview is a decision aid; in case of any discrepancy, the current official Microsoft page on the Windows 11 system requirements always applies.

How do I check TPM 2.0 and Secure Boot manually?

Checking TPM 2.0 in Windows

Press Windows key + R, type tpm.msc and confirm. In the "TPM Management on Local Computer" window, the status should report that the TPM is ready for use. Under "TPM Manufacturer Information," the specification version must show 2.0. If Windows reports that no compatible TPM was found, the feature may simply be disabled in the UEFI firmware depending on the motherboard. Microsoft describes the check and typical firmware labels in the guide Enable TPM 2.0 on your PC.

Checking UEFI and Secure Boot

Press Windows key + R again, type msinfo32 and open System Information. Look in the system summary for "BIOS Mode" and "Secure Boot State." For Windows 11, the device must support UEFI and Secure Boot. If Secure Boot shows "Off," the feature may possibly be enabled in the firmware. If BIOS Mode shows "Legacy," switching over is more demanding, because the partition style and boot mode must match.

Only change firmware settings based on your device or motherboard manufacturer's documentation. Back up important data beforehand and, if applicable, keep recovery information ready for any existing device encryption. The labels vary: TPM can, for example, appear as "Intel PTT," "AMD fTPM," "Security Device" or similar.

PC Health Check or manual check: which is better?

Why do PC Health Check and Windows Update contradict each other?

After changing the processor, motherboard or security settings, PC Health Check may already show "compatible" while Windows Update still shows the old status. Microsoft points out that updating the eligibility information can take up to 24 hours. Restart the PC, run the check again and check Windows Update once more later.

If the display remains unchanged, Microsoft describes a manual re-evaluation via Task Scheduler or an administrator command prompt. Use the original guide linked above for this, so the task path and command match Microsoft's current documentation exactly. On a managed company PC, the internal IT department is responsible, since policies or a planned rollout can additionally control the offer.

What to do if the PC is not compatible?

TPM or Secure Boot are present but disabled

First check the manufacturer's manual and only enable the clearly matching option. Then start Windows, check tpm.msc and msinfo32 again and then repeat PC Health Check. A disabled feature is something different from a feature that is not technically present at all.

RAM or storage is not sufficient

On some PCs, memory or the drive can be upgraded. What matters are the specifications of the specific device: soldered RAM, free slots, drive format and manufacturer limits differ. Also plan for more than just the 64 GB minimum. Windows, updates, applications and your own data need free space on an ongoing basis.

The processor is not supported

A fast clock speed alone is not enough; the exact processor model must be supported. If it is not listed, a clean solution often requires switching platforms or getting a different device. Microsoft advises against bypassing the hardware check: unsupported installations do not receive regular support, and updates - including security updates - are not guaranteed.

The PC is compatible

Create a backup and only then choose the right edition. Our comparison Windows 11 Home or Pro helps with features and intended use. For the process, the Windows 11 installation guide is available; if you prefer installation media, read the guide Installing Windows 11 via USB stick.

Frequently asked questions about Windows 11 compatibility

How can I check whether my PC supports Windows 11?

First use Microsoft's PC Health Check and click "Check now." If the result is negative, also check TPM 2.0 with tpm.msc and UEFI and Secure Boot with msinfo32.

Is TPM 2.0 really required for Windows 11?

Yes. TPM 2.0 is part of Microsoft's minimum requirements for Windows 11. The module may be present in the PC but disabled in the UEFI firmware.

What can I do if Secure Boot is disabled?

Use msinfo32 to check whether the PC is running in UEFI mode and supports Secure Boot. Only enable the feature following your device or motherboard manufacturer's instructions, and back up important data beforehand.

Can I install Windows 11 on unsupported hardware?

Technical workarounds exist, but Microsoft advises against installing on unsupported hardware. For such devices, support and updates - including security updates - are not guaranteed.

Does a Windows 11 product key make my PC compatible?

No. A product key concerns licensing and activation; it does not change hardware compatibility. So check the PC before choosing an edition.
