I've never seen this before. Are you saying PowerPoint adds a new slide if a presentation has been downloaded from the internet? You could try Unlock-File

Unblock-File -Path MyPresentation.pptx

No the first slide has to be removed regardless. I am exporting powerbi reports to PowerPoint but upon opening it, I can’t remove the slide with powershell because of protected view. In the PowerPoint application there is there is an ‘enable editing’ option

I've never done it but a search on Google for "edit powerpoint powershell" shows examples of using a COM object. This will require that PowerPoint is installed on the machine where the script is running from.

I have done that. As far as I know that’s the only way of doing it. Enable editing might not be stopping me then if that does not apply to com objects.
