Get-Win11Readiness.ps1

<#
.SYNOPSIS
    Check if a computer is ready for Windows 11 based on TPM and SecureBoot status
.DESCRIPTION
    Built because the official Microsoft GUI solution doesn't work for enterprise managed devices
    Can be added as an SCCM script, an Intune script, etc for scale
    Can output to a CSV file on a local machine or to a fileshare
.EXAMPLE
    PS C:\> .\Get-Win11Readiness.ps1 -Simple
    
    Returns "Ready for Windows 11: True" (or False as appropriate)
.EXAMPLE
    PS C:\> .\Get-Win11Readiness.ps1 -Silent -File "\\Server\Share\Win11Readiness.csv"
    
    Outputs system detils to the specified CSV file. Can be run multiple times or against multiple computers
.EXAMPLE
    PS C:\> .\Get-Win11Readiness.ps1 | Out-GridView
    
    Creates a GUI window displaying details about the Windows 11 readiness state
.INPUTS
    None
.OUTPUTS
    Win11Readiness Custom Object. Can be piped into other commands as needed.

    To-Do:
    Fine-tune hardware details to better handle how different manufacturers report model/serial/etc
    Make more end-user friendly. Integrate into PSADT for example to provide popups

    Version History:
    1.0.4: Fixed parsing issue with CPU evaluation
    1.0.3: Added CPU, RAM and storage checks
    1.0.2: Added Secure Boot certificate checks
    1.0.1: Fixed ability to gather Lenovo BIOS version
    1.0: Initial Release
