Microsoft’s Windows 11 brings several modern features and enhanced security — but with that also came restrictive minimum system requirements. Many users discovered that relatively recent PCs, including some only a few years old, were suddenly “too old” for the upgrade.
If you’ve encountered the dreaded message:
“This PC Doesn’t Currently Meet the Minimum System Requirements to Run Windows 11,”
you’re not alone — but there is a way forward.
In this guide, we’ll walk you through how to install Windows 11 on unsupported hardware by bypassing the TPM, CPU, and Secure Boot checks. We’ll also cover the risks involved and how to make an informed decision.
🔒 Why Windows 11 Has These Restrictions
Windows 11 enforces requirements like TPM 2.0, Secure Boot, and modern processors primarily for security reasons:
- TPM 2.0 (Trusted Platform Module) enables device encryption and protects sensitive credentials.
- Secure Boot ensures only trusted software runs at boot.
- Virtualization-Based Security (VBS) includes features like:
- Hypervisor-Protected Code Integrity (HVCI)
- Credential Guard
- Secure Launch
- System Management Mode Protection
These features existed in Windows 10 but were optional. In Windows 11, Microsoft now requires them to be enabled by default — a decision aimed at enforcing better out-of-the-box security.
⚠️ Should You Bypass These Restrictions?
Before proceeding, understand the risks:
- Lack of updates: Microsoft may block unsupported systems from receiving future updates.
- Security concerns: Without TPM or Secure Boot, you lose key protections.
- Support issues: Software vendors might deny support on unsupported hardware.
⚠️ Disclaimer: This article is for educational purposes only. Modifying system requirements and bypassing official checks carries risks. Proceed at your own discretion, and ensure you have full system backups.
✅ Step 1: Check If You Have a Hidden TPM
Some systems may already support TPM via firmware:
- On Intel systems, it’s called PTT (Platform Trust Technology).
- On AMD systems, it’s fTPM (Firmware TPM).
You can enable these in your BIOS/UEFI:
- Restart your PC and enter BIOS (usually via Delete, F2, or by holding Shift + Restart → Advanced Options → UEFI Settings).
- Look for Security or Advanced tabs.
- Enable PTT or fTPM and Secure Boot if available.
If found, you may not need any workarounds at all.
💽 Step 2: Prepare Windows 11 Installation Media
➡️ Download Windows 11 ISO:
Official Microsoft Page
➡️ Create Installation Media:
Use the “Create Windows 11 Installation Media” tool from the above page to create a bootable USB drive.
🔧 Step 3A: Upgrade with Incompatible CPU/TPM (But Still Present)
If your system has a TPM 1.2 or unsupported CPU, you can enable installation by modifying the registry.
💡 Registry Hack for In-Place Upgrade:
- Mount the ISO and run Setup.exe.
- When blocked, open the Registry Editor (
regedit). - Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup - If “MoSetup” doesn’t exist, create it.
- Right-click → New > DWORD (32-bit) → Name it:
AllowUpgradesWithUnsupportedTPMOrCPU - Set its value to 1.
- Restart the installer.

🔧 Step 3B: Fresh Install Without TPM or Secure Boot
This method is riskier but possible with a USB installer.
- Boot from the Windows 11 USB.
- When you see the error message about system requirements:
- Go back a step
- Press Shift + F10 to open Command Prompt.
- Type
regeditto open the Registry Editor. - Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\Setup - Create a new key named:
LabConfig - Inside this key, create the following DWORD values:
BypassTPMCheck= 1BypassSecureBootCheck= 1- (Optional)
BypassRAMCheck= 1 (only if you truly have less than 4GB RAM — not recommended)
- Close everything and resume the setup.
🧼 Optional: Remove Unsupported Hardware Watermark
Recent builds may show a watermark on the desktop if you bypass requirements.
To remove it:
- Go to:
HKEY_CURRENT_USER\Control Panel\UnsupportedHardwareNotificationCache - Create or modify the DWORD
SV2and set it to 0.
🧠 What You’re Giving Up
- Drive Encryption: Without TPM, BitLocker may be unavailable or harder to configure.
- Future Updates: Microsoft may block you from installing newer builds.
- Support: You may not receive help from software vendors or Microsoft.
🧭 Final Thoughts: Is It Worth It?
If your device is only slightly outdated, bypassing the requirements might let you enjoy Windows 11 with minimal downsides — especially for home users.
However, if you’re using your system for business, it’s best to:
- Stay on Windows 10 (supported until October 2025).
- Or upgrade to compatible hardware.
For those who are technically inclined and understand the trade-offs, bypassing can be a viable short-term solution — just stay informed and be ready to reinstall or revert if needed.
🔄 Alternative: Consider Linux
If you’re tired of Microsoft’s limitations, you might explore switching to a Linux distro like Ubuntu or Fedora — both modern, secure, and free.
