Hardware Requirements for Windows Editions
When installing modern Windows editions (like Windows 10 and Windows 11), the operating system checks that certain hardware features exist. These are important for security, performance, and compatibility.
Two critical hardware requirements you must know for the exam are:
1. Trusted Platform Module (TPM)
What it is:
TPM is a small security chip built into a computer’s motherboard. Think of it as a hardware vault that securely stores sensitive information like encryption keys, digital certificates, and passwords.
Key points for the exam:
- Purpose: Provides hardware-level security to prevent unauthorized access, protect files, and support features like BitLocker encryption.
- TPM Versions:
- TPM 1.2 – older version, supported by some earlier Windows editions.
- TPM 2.0 – required for Windows 11. Windows 10 can use it but doesn’t require it.
- Function in Windows:
- Works with Windows security features like BitLocker (disk encryption), Windows Hello (biometric login), and secure boot processes.
- Where it lives: Usually embedded on the motherboard. Some PCs allow TPM to be enabled or disabled in BIOS/UEFI settings.
Exam tip: Know that Windows 11 requires TPM 2.0, but Windows 10 does not strictly require it. This is often tested as part of hardware requirements.
2. Unified Extensible Firmware Interface (UEFI)
What it is:
UEFI is the modern replacement for the older BIOS (Basic Input/Output System). It’s the firmware that starts up your computer and prepares it to load the operating system.
Key points for the exam:
- Purpose: Initializes hardware components (CPU, RAM, storage) and ensures a secure startup process.
- Benefits over BIOS:
- Supports larger hard drives (over 2 TB).
- Faster boot times.
- Provides a secure boot feature that prevents malicious software from loading before Windows starts.
- Secure Boot: A UEFI feature that ensures only trusted software signed by Microsoft can boot. This is required for Windows 11 security compliance.
- Interaction with TPM: UEFI works with TPM to provide a secure, hardware-based security foundation.
Exam tip: Know that Windows 11 requires UEFI with Secure Boot enabled, whereas Windows 10 can work with either UEFI or legacy BIOS, though UEFI is recommended.
Summary Table for Exam
| Feature | Windows 10 Requirement | Windows 11 Requirement | Purpose |
|---|---|---|---|
| TPM | Recommended (any version) | Required (TPM 2.0) | Hardware security, encryption keys, secure login |
| UEFI | Recommended (supports Secure Boot) | Required (Secure Boot enabled) | Boot process, hardware initialization, malware protection |
Why it Matters for the Exam
- Microsoft exams often test minimum hardware requirements for different editions.
- Key differences between Windows 10 vs Windows 11 often involve TPM and UEFI.
- Understanding how TPM and UEFI work together helps answer questions about security features like BitLocker and Secure Boot.
