⚠️ Important Note (Windows 10 Support Status): Microsoft officially ended mainstream support for Windows 10 on October 14, 2025. If your PC isn't eligible for Windows 11, you're now running an unsupported OS. This guide shows exactly how to check your hardware compatibility — TPM 2.0, Secure Boot, CPU, and RAM — using only built-in Windows tools.
Microsoft's push toward tighter system security has made upgrading from Windows 10 to Windows 11 a smooth process for some, but a confusing roadblock for millions of others. If you've tried checking your system compatibility, you might have been greeted by cryptic errors like "This PC doesn't currently meet the minimum system requirements" or "Compatible TPM cannot be found."
To give you an honest, real-world look at how to check your PC's compatibility, I ran a hands-on diagnostic test on my older desktop rig powered by an Intel Core i5-4570 CPU. In this step-by-step guide, I'll walk you through the three exact methods I used to verify hardware compatibility — along with raw error codes and what they actually mean for the future of your PC.
📋 What You'll Learn
Method 1: Check Core Hardware via System Information (msinfo32)
Before worrying about complex security features like TPM, first check whether your foundational hardware — processor, RAM, and BIOS mode — meets Microsoft's baseline criteria for Windows 11.
- Open the Run dialog — Press
Win + R. - Launch System Information — Type
msinfo32and hit Enter. - Review the summary window — The System Summary screen shows your Processor, BIOS Mode, and other key specs.
Here's what I found: Looking at my actual diagnostic readout, here's how an older system holds up against Windows 11 specs:
- Processor (Intel Core i5-4570 @ 3.20GHz): This is where my system hits its first major roadblock. Microsoft officially requires an 8th Generation Intel processor or newer (or AMD Ryzen 2000 series and above). My i5-4570 is a 4th-generation chip — officially unsupported for Windows 11.
- BIOS Mode (UEFI): Windows 11 requires modern UEFI boot instead of legacy BIOS. My system successfully runs in UEFI mode. ✅
- Secure Boot State (Off): Secure Boot prevents malware from loading at startup. My system supports UEFI, but Secure Boot is currently turned Off in BIOS.
Method 2: Test for TPM 2.0 via Trusted Platform Module Management (tpm.msc)
The single biggest point of confusion for users upgrading to Windows 11 is the TPM 2.0 requirement. TPM is a physical (or firmware-based) chip that securely stores cryptographic keys, passwords, and digital certificates. Windows 11 strictly mandates TPM 2.0.
- Open the Run dialog — Press
Win + R. - Launch TPM Management — Type
tpm.mscand press Enter. - Read the status message at the top of the window.
What this confirmed: Instead of a version number, my screen returned a clear diagnostic status: "Compatible TPM cannot be found."
This confirms two possibilities:
- My motherboard (an older Intel H81 chipset) lacks a physical TPM module entirely.
- Firmware-based TPM (fTPM/PTT) is either unsupported by the 4th-gen CPU architecture or disabled in the BIOS.
Method 3: Verify Status in Windows Update Settings
If you'd rather skip command-line consoles, Microsoft provides an automated status banner directly inside Windows Update.
- Open Settings — Press
Win + I. - Go to Update & Security from the main Settings screen.
- Select Windows Update from the left-hand menu and check the status banner.
The verdict: On the right-hand panel, my desktop displayed a clear red-and-black notification: "Your PC doesn't currently meet the minimum system requirements to run Windows 11." Since this machine is on an older Windows 10 build, it also flagged: "Your version of Windows has reached the end of support."
Summary Checklist: Minimum Requirements vs. My Test Machine
| Windows 11 Requirement | Official Minimum Standard | My Test Machine (i5-4570) | Status |
|---|---|---|---|
| Processor | 1 GHz+, 2+ cores, 8th Gen+ | Intel Core i5-4570 (4th Gen) | Failed |
| RAM | 4 GB minimum | 8 GB / 16 GB | Passed |
| Storage | 64 GB or larger drive | 256 GB SSD | Passed |
| System Firmware | UEFI, Secure Boot capable | UEFI Mode (Secure Boot Off) | Needs Configuration |
| TPM | Trusted Platform Module 2.0 | No Compatible TPM Found | Failed |
What Should You Do If Your PC Fails the Test?
If your diagnostic matches mine — unsupported processor, missing TPM 2.0, or disabled Secure Boot — you have three main paths forward:
- Enable TPM & Secure Boot in BIOS (for 8th Gen+ PCs) — If your PC has a newer processor but still failed, your TPM chip might simply be turned off. Boot into BIOS/UEFI settings and look for Intel PTT, AMD fTPM, or Security Chip, then toggle it to Enabled.
- Continue using Windows 10 safely — Windows 10 remains fully functional for daily productivity, media, and general gaming, though it no longer receives security patches.
- Use advanced bypass methods (experienced users only) — Tools like Rufus allow you to create modified Windows 11 installation media that bypasses TPM 2.0, CPU, and Secure Boot checks. Keep in mind Microsoft may withhold future feature updates on unsupported hardware.
Final Thoughts
Checking your PC's compatibility before attempting a major OS upgrade saves time and prevents unexpected system instability. By spending a few minutes running msinfo32 and tpm.msc, you get an accurate, clear picture of your desktop's hardware health — and a clear decision path forward.
