Windows 11 System Requirements: The Direct Answer
Windows 11 requires a compatible 64-bit processor, 4GB RAM, 64GB storage, TPM 2.0, and Secure Boot. Most PCs from 2018 onward qualify. The fastest way to check is Microsoft's free PC Health Check app, which scans your hardware and tells you instantly if you are compatible.
The Full Requirements List
- Processor: 1GHz or faster, 2+ cores, compatible 64-bit
- RAM: 4GB minimum
- Storage: 64GB minimum
- TPM: version 2.0 required
- Secure Boot: capable and enabled
- Graphics: DirectX 12 compatible with WDDM 2.0 driver
- Display: 9" or larger, 720p minimum
How to Check Compatibility
Download Microsoft's PC Health Check app and run it. It scans your processor, RAM, storage, TPM, and Secure Boot, then gives a clear yes or no with details on any failing component.
The TPM 2.0 Hurdle
TPM 2.0 is the requirement that trips up most people. It is a security chip built into most modern CPUs and motherboards, but it is often disabled by default. Check your BIOS/UEFI settings for "TPM," "PTT" (Intel), or "fTPM" (AMD) and enable it — this alone makes many "incompatible" PCs compatible.
If Your PC Is Not Compatible
First, check BIOS for a disabled TPM — enabling it often solves the issue. If your hardware genuinely is too old, weigh your options: extended Windows 10 security measures or a hardware upgrade. With Windows 10 support ended, staying secure long-term means moving to compatible hardware eventually.
The Bottom Line
Check compatibility with PC Health Check, enable TPM 2.0 in BIOS if needed, and most modern PCs will run Windows 11 fine. Once compatible, see the product below for a genuine Windows 11 Pro key.
