Error 0x800705b4: Hardware Security Requirements Not Met

Error Message

Securing your hardware (Failed: 0x800705b4) Joining your organization's network (Previous step failed) Registering your device for mobile management (Previous step failed)

Error Details​

PropertyValue
Error Code (Hex)0x800705b4
Error Code (Dec)-2147023436

Description​

info

This error occurs during Windows Autopilot self-deploying mode when the device doesn't meet the required hardware or software specifications. The device must have a physical TPM 2.0 chip and run a supported Windows version. Virtual TPMs (like in Hyper-V VMs) and TPM 1.2 chips are not supported.

Common Causes​

🔐 TPM Requirements​

Security failures often stem from TPM incompatibility. Virtual TPM not supported. TPM 1.2 insufficient for requirements. Physical TPM 2.0 chip required. Understanding hardware requirements is crucial for successful deployment.

💻 Windows Version Issues​

Version-related complications can prevent deployment. Windows build might be outdated. Hybrid join scenarios need newer versions. Version requirements vary by deployment type. These version factors require verification and possible updates.

System Requirements​

TPM Requirements​

  • Physical TPM 2.0 chip required
  • Virtual TPMs not supported
  • TPM 1.2 not supported
  • No exceptions available

Windows Version Requirements​

  • Standard deployment:
    • Windows 10 build 1709 or later
  • Microsoft Entra hybrid join:
    • Windows 10 build 1809 or later

Resolution Steps​

1️⃣ Verify TPM Status​

Check TPM specifications:

  1. Open TPM Management Console (tpm.msc)
  2. Verify TPM version and type
  3. Confirm physical TPM presence
  4. Document TPM specifications

2️⃣ Check Windows Version​

Verify Windows build:

  1. Open System Information
  2. Check Windows version and build
  3. Compare against requirements
  4. Plan updates if needed

3️⃣ System Updates​

If version requirements not met:

  1. Backup important data
  2. Download required Windows version
  3. Perform system update
  4. Verify new build number

Best Practices​

👨‍💻 For IT Administrators​

Effective deployment requires attention to hardware specifications. Implement comprehensive hardware verification. Maintain documentation of system requirements. Develop clear procedures for version validation. Create systematic approaches to deployment preparation. Consider implementing automated compliance checking.

🔄 For System Management​

Successful deployment requires proper hardware and software configuration. Develop clear processes for system verification. Maintain accurate documentation of requirements. Implement thorough testing procedures for deployment. Create comprehensive documentation of validation steps.

Troubleshooting Tips​

Hardware Verification

When addressing security requirements, focus on hardware validation. Verify physical TPM presence. Check TPM version carefully. Test TPM functionality. Monitor for hardware compatibility.

Important Considerations

System requirements are strict. No exceptions for virtual TPMs. Version requirements vary by scenario. Consider deployment type requirements. Monitor system specifications carefully.
