Test-Win11Compatibility

Test-Win11Compatibility is a PowerShell script that evaluates a Windows system's readiness for Windows 11. It checks hardware (CPU, RAM, storage), firmware (TPM 2.0, Secure Boot), and software requirements, providing a detailed report with pass/fail indicators and remediation advice. Ideal for IT administrators and users planning a Windows 11 upgrade, this script is part of the Test-Win11Compatibility repository.

Features

• Validates CPU (generation/cores), TPM 2.0, Secure Boot, RAM (≥4GB), and storage (≥64GB).
• Confirms UEFI firmware and DirectX 12/WDDM 2.0 graphics compatibility.
• Advises on Microsoft Account requirements (optional in some cases).
• Outputs a color-coded console report with detailed explanations.
• Optionally exports results to CSV, XML, or JSON files, or generates an HTML report.
• Non-invasive, read-only checks with no system modifications.

Requirements

• PowerShell Version: 5.1 or later (PowerShell 7.x recommended).
• Operating System: Windows 10 (version 2004+) or Windows 11, x64 architecture.
• Modules: None; uses built-in cmdlets (Get-CimInstance, Get-WmiObject, dism, Get-ComputerInfo).
• Permissions: Standard user for most checks; Administrator for full TPM/Secure Boot access unless -NoElevation is used.
• Dependencies: .NET Framework 4.8 or later (included in supported Windows versions).

Installation

1. Clone the Repository:

   git clone https://github.com/ndomako/Test-Win11Compatibility.git
   cd Test-Win11Compatibility

2. Download the Script:

   • Visit Test-Win11Compatibility.ps1.
   • Click "Raw" and save as Test-Win11Compatibility.ps1 (e.g., to C:\Scripts\).

3. Set Execution Policy (if needed):

   • Run as Administrator:

     Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Usage Examples

1. Console Report: Display compatibility results in PowerShell:

   .\Test-Win11Compatibility.ps1

   • Shows a formatted report with ✅ Pass, ❌ Fail, or ⚠️ Warning for each requirement.

2. Export to JSON: Save results to a JSON file for analysis:

   .\Test-Win11Compatibility.ps1 -ExportResults -ExportFormat JSON -ExportPath "C:\Reports\Win11Report.json"

   • Generates a JSON file with requirement details and recommendations.

3. Generate HTML Report: Create an HTML report for sharing:

   .\Test-Win11Compatibility.ps1 -ExportHTML -ExportPath "C:\Reports\Win11Report.html"

Parameters

• -DriveLetter (Optional, String):

  • Description: Specifies the drive letter to check for storage requirements (e.g., available disk space). Must be a single uppercase letter (A-Z).
  • Expected Type: System.String (e.g., "C").
  • Default: "C".
  • Example: -DriveLetter D.

• -ExportResults (Optional, Switch):

  • Description: Enables exporting the compatibility results to a file in the format specified by -ExportFormat.
  • Expected Type: SwitchParameter (no value needed).
  • Default: False (no export).
  • Example: -ExportResults.

• -ExportFormat (Optional, String):

  • Description: Specifies the file format for exported results when -ExportResults is used. Valid options are XML, JSON, or CSV.
  • Expected Type: System.String (must be "XML", "JSON", or "CSV").
  • Default: "XML".
  • Example: -ExportFormat CSV.

• -ExportPath (Optional, String):

  • Description: Specifies the file path or directory to save the exported results. If a directory is provided, the script generates a filename with a timestamp (e.g., Win11Report_2025-10-20.xml). If a file path is provided, it uses the specified filename.
  • Expected Type: System.String (e.g., "C:\Reports\Win11Report.csv" or "C:\Reports\").
  • Default: ".\" (current directory).
  • Example: -ExportPath "C:\Reports\report.json".

• -ExportHTML (Optional, Switch):

  • Description: Generates an HTML report of the compatibility results, saved to the path specified by -ExportPath. Overrides -ExportFormat if both are specified.
  • Expected Type: SwitchParameter (no value needed).
  • Default: False (no HTML export).
  • Example: -ExportHTML.

• -NoElevation (Optional, Switch):

  • Description: Runs the script without requiring administrative privileges. Some checks (e.g., TPM, Secure Boot) may be limited or skipped if elevation is not available.
  • Expected Type: SwitchParameter (no value needed).
  • Default: False (attempts elevated checks).
  • Example: -NoElevation.

Output

• Console: Color-coded report with:
  • Requirement headers (e.g., "CPU Check", "TPM Check").
  • Status indicators and details (e.g., "TPM: 2.0 - Compatible").
  • Summary (e.g., "7/8 Requirements Met").
• File Export (with -ExportResults or -ExportHTML): Results in CSV, XML, JSON, or HTML format, with columns/fields for Requirement, Status, Details, and Recommendation.
• Exit Code: 0 (fully compatible), 1 (issues detected).

No system changes are made.

Error Handling and Known Issues

• Errors:

  • Permission Denied (TPM/Secure Boot): Run as Administrator or use -NoElevation:

    Start-Process powershell -Verb RunAs -ArgumentList "-File .\Test-Win11Compatibility.ps1"

  • WMI/CIM Failure: Ensure WMI service is running:

    Restart-Service Winmgmt

  • Old Windows Version: Update to Windows 10 2004+ if warnings appear.

• Issues:

  • Virtual machines may misreport TPM/Secure Boot; verify in host BIOS/UEFI.
  • ARM64 systems (e.g., Surface Pro X) may show false negatives.
  • DirectX check failures? Confirm with dxdiag.

• Troubleshooting:

  1. Check execution policy: Get-ExecutionPolicy.
  2. Test cmdlets: Get-Tpm, Get-CimInstance Win32_OperatingSystem.
  3. Review Event Logs (Event Viewer > Windows Logs > System).
  4. Report issues at GitHub Issues.
