The official requirements

Part	Required
Processor	64-bit, 1 GHz or faster, 2+ cores, from the supported list (generally Intel 8th gen and newer, AMD Ryzen 2000 and newer)
RAM	4 GB or more
Storage	64 GB or more
Firmware	UEFI with Secure Boot
TPM	Version 2.0
Graphics	DirectX 12 compatible with a WDDM 2.0 driver
Display	Larger than 9 inches at 720p

Step 1: a quick check

Press Win + R, type tpm.msc and press Enter.
Read “TPM Manufacturer Information”: the version should be 2.0 and the status “The TPM is ready for use”.
Press Win + R and type msinfo32, then check “BIOS Mode” reads UEFI and “Secure Boot State” reads On.

If tpm.msc says “Compatible TPM cannot be found”, the feature is often switched off in the BIOS rather than missing. The next step turns it on.

Step 2: enable TPM in the BIOS

Restart and press your BIOS key (usually Delete, F2, F10 or Esc). Open the security or Advanced settings and look for:

On Intel PCs: PTT (Intel Platform Trust Technology), enable it.
On AMD PCs: fTPM (AMD CPU fTPM), enable it.
Some boards call it Security Device Support or TPM Device.

Save, restart and run tpm.msc again.

Step 3: UEFI and Secure Boot

If msinfo32 shows BIOS Mode as “Legacy”, the disk is MBR and must be converted to GPT. Microsoft’s MBR2GPT tool converts it without deleting files, but back up your files first. Then enable UEFI and Secure Boot in the BIOS.

What if my PC does not qualify?

If the CPU is unsupported or a part is old you can stay on Windows 10 (read Windows 10 or 11 for the limits) or upgrade the parts. See our ready PC builds or single upgrades in our services.

Converting the disk from MBR to GPT in detail

If your PC boots in Legacy mode and the disk is MBR, you can convert it with Microsoft’s MBR2GPT tool from inside Windows without deleting files. Open Command Prompt as administrator and run the validation first:

mbr2gpt /validate /allowFullOS

If validation succeeds, run the conversion:

mbr2gpt /convert /allowFullOS

After conversion restart, enter the BIOS, change the boot mode from Legacy to UEFI and enable Secure Boot. If validation fails, do not continue; read the failure reason first. Most important: take a full backup of your files before any change to the disk.

Common questions about the requirements

Is TPM 2.0 really required? Yes. The official requirements call for TPM version 2.0, and most modern PCs have one built into the CPU (PTT or fTPM) that is simply switched off.
My CPU is old and not on the list; what can I do? Unsupported CPUs can run Windows 11 through unofficial methods, but Microsoft does not support them and updates may not arrive, so we do not recommend it for a PC you depend on.
Is there an official checker? Yes. Microsoft provides the PC Health Check app, which tells you whether your PC qualifies and why not.
Is 4 GB RAM enough? It is the minimum to run; 8 or 16 GB is better for comfortable gaming and browsing.
