🧠 Overview

Our Windows 11 Compatibility Checker is a small, user-friendly diagnostic tool designed to determine if your PC is eligible for Windows 11 — even if Microsoft’s default compatibility checker says otherwise.

Unlike Microsoft’s strict enforcement, our tool evaluates both official requirements and real-world upgrade paths that may still allow installation with custom configuration or technician support.

🔍 What the Compatibility Checker Analyzes

The tool performs a full scan of key system components using safe, read-only PowerShell commands. Below is a breakdown of each metric it checks:

1. CPU (Processor)

• What it checks: Number of logical cores and clock speed.

• Requirement: At least 2 cores running at 1.0 GHz or faster.

• Why it matters: Ensures your system can handle the Windows 11 kernel and multitasking.

2. RAM (Memory)

• What it checks: Total physical memory installed across all slots.

• Requirement: Minimum of 4 GB.

• Why it matters: Windows 11 needs enough memory to run background services and apps efficiently.

3. Storage

• What it checks: Combined total of all internal fixed disks (e.g., SSD or HDD).

• Requirement: Minimum of 64 GB free space.

• Why it matters: Ensures there is room for Windows installation, updates, and recovery partition.

4. UEFI (Unified Extensible Firmware Interface)

• What it checks: Whether your system is booting in UEFI mode (modern BIOS).

• Requirement: UEFI boot mode must be enabled.

• Why it matters: Legacy BIOS is not supported in official Windows 11 installation.

5. Secure Boot

• What it checks: If Secure Boot is supported and enabled.

• Requirement: Secure Boot must be enabled.

• Why it matters: Protects your boot process from malware and rootkits.

6. TPM (Trusted Platform Module)

• What it checks: Detects presence and version of TPM chip.

• Requirement: TPM version 2.0 must be installed and active.

• Why it matters: TPM provides hardware-based encryption, used by features like BitLocker and Windows Hello.

📋 Results & What They Mean

The tool categorizes your system into one of three statuses:

✅ Compatible – Ready for Windows 11

• All critical requirements are met. – Proceed with Install or Upgrade

• You can upgrade immediately through official or assisted channels.

⚠️ Missing Security Requirements – Upgrade Still Possible

• Your system passes CPU, RAM, and storage checks.

• But it lacks Secure Boot and/or TPM 2.0.

• You may still upgrade via a custom installation with help from our technicians.

• ➕ Windows11Upgrade.net offers full installation services for these scenarios.

❌ Not Compatible – Major Requirements Missing

• One or more of CPU, RAM, or storage is below the required threshold. – Windows will not install, if you do, it will not run correctly

• In this case, an upgrade is not recommended unless you replace or upgrade hardware. – May be more cost effective to replace computer.
