function Get-OSInfo {
    <#
        .SYNOPSIS
        Retrieves detailed information about the operating system version and architecture.

        .DESCRIPTION
        This function queries both the Windows registry and the Win32_OperatingSystem class to gather comprehensive information about the operating system. It returns details such as the release ID, display version, name, type (Workstation/Server), numeric version, edition ID, version (object that includes major, minor, and build numbers), and architecture (OS architecture, not processor architecture).

        .EXAMPLE
        Get-OSInfo

        This example retrieves the OS version details of the current system and returns an object with properties like ReleaseId, DisplayVersion, Name, Type, NumericVersion, EditionId, Version, and Architecture.

        .EXAMPLE
        (Get-OSInfo).Version.Major

        This example retrieves the major version number of the operating system. The Get-OSInfo function returns an object with a Version property, which itself is an object containing Major, Minor, and Build properties. You can access these sub-properties using dot notation.

        .EXAMPLE
        $osDetails = Get-OSInfo
        Write-Output "OS Name: $($osDetails.Name)"
        Write-Output "OS Type: $($osDetails.Type)"
        Write-Output "OS Architecture: $($osDetails.Architecture)"

        This example stores the result of Get-OSInfo in a variable and then accesses various properties to print details about the operating system.

            Depending on the error code, it writes appropriate warning messages or throws the error.

        .PARAMETER ErrorRecord
            The ErrorRecord object that represents the error that was caught. This object contains

            This example shows how you might use the Handle-Error function in a try-catch block.
            If an error occurs in the try block, the catch block catches it and calls Handle-Error,
