WindowsEventLog: MaximumSizeInBytes change maximum limit to exceed 4GB

Problem description

Currently the MaximumSizeInBytes is limited to a max of 4GB. This should be expanded to 2TB. Cannot find the official documentation about this but there is a recent blog post about it where it mentions that it can be set to 2TB

You can set a maximum log size value of between 1024 and 2,147,483,647 kilobytes in multiples of 64 kilobytes. That's an approximate maximum log file size of 2 TB if you're feeling relaxed about the amount of storage you have. Microsoft’s current recommendation for how to configure this setting is 4GB.

Verbose logs

PowerShell DSC resource DSC_WindowsEventLog  failed to execute Set-TargetResource functionality with error message: Cannot validate argument on parameter
'MaximumSizeInBytes'. The 21474836480 argument is greater than the maximum allowed range of 4294967296. Supply an argument that is less than or equal to 4
294967296 and then try the command again

DSC configuration

$InvokeParams = @{
    Method     = 'Set'
    ModuleName = 'ComputerManagementDsc'
    Name       = 'WindowsEventLog'
    Property   = @{
        LogName            = 'System'
        IsEnabled          = $true
        LogMode            = 'Circular'
        MaximumSizeInBytes = 21474836480
    }
}
Invoke-DscResource @InvokeParams

Suggested solution

Change the ValidateRange in the MaximumSizeInBytes parameter from [ValidateRange(64KB, 4GB)] to [ValidateRange(64KB, 2TB)]

Start at the WindowsEventLog resource's MaximumSizeInBytes parameter and inspect its ValidateRange constraint. Verify the accepted range with the provided Invoke-DscResource configuration, then confirm that values above 4GB and up to the requested limit are accepted without validation errors.
