Windows Hardware Requirements for Upgrade Decisions for A+
Short answer
Modern Windows upgrade paths (notably Windows 10 -> Windows 11) include hardware requirements that, if unmet, will block or warn on in-place upgrades. A technician must check Device Security or firmware settings for TPM, verify UEFI mode is present, and note Secure Boot status. If TPM is present but disabled, firmware settings may enable it; if TPM is absent, hardware replacement or a different upgrade strategy is necessary.
Why it appears on the exam
- Recognition: Given a Device Security screenshot showing TPM absent, decide the impact on an intended Windows 11 upgrade. - Compatibility check reports UEFI requirement; choose the technician's next verification step.
Key concepts
Concept 1
Required terms
TPM 2.0: Trusted Platform Module version 2.0 is a secure hardware component used for cryptographic operations and is a Windows 11 prerequisite in many supported upgrade scenarios. UEFI: Unified Extensible Firmware Interface, modern firmware replacing legacy BIOS, required in many Windows upgrade checks for Windows 11 and recommended for modern OS features. Secure Boot: A firmware feature dependent on UEFI that helps prevent unauthorized OS loaders; often checked as part of modern upgrade compatibility but can sometimes be toggled in firmware settings.
Example
Compatibility checker fails with 'TPM 2.0 required'-the technician checks Device Security and firmware, finds TPM disabled, enables it, and reruns the check.

How Windows Hardware Requirements for Upgrade Decisions works
Modern Windows upgrade paths (notably Windows 10 -> Windows 11) include hardware requirements that, if unmet, will block or warn on in-place upgrades. A technician must check Device Security or firmware settings for TPM, verify UEFI mode is present, and note Secure Boot status. If TPM is present but disabled, firmware settings may enable it; if TPM is absent, hardware replacement or a different upgrade strategy is necessary.
Example
System uses legacy BIOS with no UEFI support; the installer blocks an in-place Windows 11 upgrade and recommends hardware planning or a clean install on compatible hardware.
Concept 3
Common confusion
- Believing TPM is only for BitLocker; TPM is also a platform requirement in some OS upgrade paths. - Confusing TPM version numbers; A+ level: recognize 'TPM 2.0' as the modern expectation for Windows 11 readiness.
Example
Compatibility checker fails with 'TPM 2.0 required'-the technician checks Device Security and firmware, finds TPM disabled, enables it, and reruns the check.
Concept 4
Core 2 (220-1202) question cues
Recognition: Given a Device Security screenshot showing TPM absent, decide the impact on an intended Windows 11 upgrade; Compatibility check reports UEFI requirement; choose the technician's next verification step.
Example
System uses legacy BIOS with no UEFI support; the installer blocks an in-place Windows 11 upgrade and recommends hardware planning or a clean install on compatible hardware.
