WindowsUtils.psm1

<#
    .SYNOPSIS
 
        Returns installed .NET version information.
 
    .DESCRIPTION
 
        This function returns .NET version information for the current, or remote computer.
        Uses the registry to retrieve .NET Framework information, and the runtime to return .NET information.
        It also returns the CLR version, and installed patches.
 
    .PARAMETER ComputerName
 
        A list of computer names. The function first tries Remote Registry, and falls back to PS Remote, in case the Remote Registry service is not running.
 
    .PARAMETER Edition
 
        The edition(s) to get version information. Default is 'All'.
 
    .PARAMETER Credential
 
        Optional credential.
 
    .PARAMETER IncludeUpdate
 
        Includes .NET patching information. This parameter is only allowed with .NET Framework.
 
    .EXAMPLE
 
        Get-InstalledDotNetInformation -ComputerName MYCOMPUTER1.contoso.com, MYCOMPUTER2.contoso.com -Edition 'DotnetFramework' -Credential (Get-Credential) -IncludeUpdate
 
    .EXAMPLE
 
        Get-InstalledDotNetInformation -Edition 'Dotnet'
 
    .NOTES
