Windows 11 System Requirements: Does Your PC Support It?
Windows 11 introduced the strictest hardware requirements of any Windows version in history. The presence of TPM 2.0, Secure Boot, and a minimum CPU generation requirement blocked millions of otherwise capable PCs from upgrading. Before purchasing a Windows 11 key, run through this checklist to confirm your machine qualifies.
Official Windows 11 Minimum Requirements
Microsoft's official minimum requirements are a starting point — meeting them means Windows 11 will install and run, though the experience may not be optimal on the lowest-spec hardware.

What Is TPM 2.0 and Why Does Windows 11 Require It?
TPM (Trusted Platform Module) 2.0 is a security chip either embedded in your motherboard or built into your CPU. It stores encryption keys, certificates, and passwords in hardware — making it much harder for malware or attackers to steal credentials. Microsoft made TPM 2.0 mandatory for Windows 11 as part of a security-first design. Most PCs made after 2017 include TPM 2.0, but it may be disabled in BIOS by default on some machines. You can check: press Windows key + R → type tpm.msc → press Enter. If it shows "TPM 2.0", you're good.
TPM Is Disabled? Here's How to Enable It
If tpm.msc shows no TPM or version 1.2, your TPM may simply be disabled in BIOS/UEFI. Restart your PC, enter BIOS (usually F2, F12, or Delete during startup), look for "Security" → "TPM" or "PTT" (for Intel) / "fTPM" (for AMD) and enable it. Save and restart — then check tpm.msc again.
Supported Processors
This is where many older PCs fall short. Windows 11 requires a processor from Microsoft's approved list. Generally: Intel 8th generation (Coffee Lake) and newer, AMD Ryzen 2000 series and newer, and Qualcomm Snapdragon 850 and newer. Notable exclusions include Intel Core i7-7700K and earlier generations — chips that were high-end just a few years ago. The full supported list is available at microsoft.com/windows/windows-11-specifications.
How to Check Compatibility Using PC Health Check
Microsoft provides a free tool called "PC Health Check" that scans your hardware and tells you definitively whether your PC supports Windows 11. Download it from microsoft.com/en-us/windows/windows-11#pchealthcheck. Run the app and click "Check Now". It will either confirm compatibility or list the specific components that fail to meet requirements.
Recommended Specs for the Best Experience
Meeting the minimum requirements gets Windows 11 running, but for a smooth, enjoyable experience — especially for multitasking, gaming, or creative work — aim for: 8GB RAM or more, an NVMe SSD (vs. HDD), a DirectX 12 Ultimate compatible GPU, and a display with 1080p or higher resolution. These aren't required, but the difference in day-to-day performance is significant.
Can You Install Windows 11 on an Unsupported PC?
Technically yes — Microsoft published a workaround involving a registry edit that bypasses the CPU and TPM checks. However, Microsoft has stated that unsupported installations will not receive Windows Updates and may show notifications about the unsupported state. For a personal test machine this might be acceptable; for a primary work or gaming PC, we recommend running supported hardware for security and stability reasons.
Quick Answers
Before You Buy a Windows 11 Key
Run the PC Health Check tool first — it takes 30 seconds and removes any guesswork. If your PC is compatible, a genuine Windows 11 Pro retail key from EvelopKeys activates in under 30 seconds and comes with a lifetime replacement guarantee. If your PC doesn't qualify, Windows 10 keys remain available and Windows 10 is supported until October 2025.
