What Are the Exact Windows 11 Requirements?
Unlike previous Windows transitions where almost any functioning PC could run the new operating system, Microsoft instituted strict hardware security baselines for Windows 11:
- Processor: 1 GHz or faster with 2+ cores on a compatible 64-bit architecture (Intel 8th Generation Core or AMD Ryzen 2000 series minimum).
- Memory & Storage: 4GB RAM (we strongly recommend 16GB for modern multitasking) and 64GB+ storage.
- Firmware: UEFI with Secure Boot enabled.
- TPM Version: Trusted Platform Module (TPM) version 2.0 cryptoprocessor chip enabled in BIOS.
Why Did Microsoft Enforce TPM 2.0?
The TPM 2.0 chip handles hardware-based cryptographic keys, BitLocker drive encryption, and Windows Hello biometric security. By isolating encryption keys away from the main operating system memory, TPM mitigates kernel-level rootkits and firmware attacks.

What Should You Do If Your Computer is "Unsupported"?
If Microsoft’s PC Health Check app tells you that your machine cannot run Windows 11, do not panic. You have three practical choices:
- Keep Running Windows 10 Safely: With robust Bitdefender security and safe computing practices, an existing machine can continue working securely for everyday tasks.
- Hardware Rejuvenation / Bypass Optimization: For computers with fast processors (such as 7th Gen Intel i7) that lack native TPM support, Dimension Computer can perform a clean installation with enterprise stability patches.
- Certified Refurbished Business Upgrade: Switch to an enterprise Grade-A Dell OptiPlex or Latitude laptop with native Windows 11 Pro support starting under $350.
