The primary program used to open .pptx files is Microsoft PowerPoint, which is specifically designed to create, open, view, and edit PowerPoint presentations. Microsoft PowerPoint is part of the Microsoft Office suite and provides full support for the formatting and features of .pptx files.
Other programs that can open .pptx files include:
- LibreOffice and OpenOffice, free office suites that support .pptx files.
- Google Slides, available online via Google Drive, which allows uploading and editing of .pptx files.
- Apple Keynote on Mac, which supports .pptx files.

If Microsoft PowerPoint is not installed, users can also open .pptx files using free viewers or compatible office software but the full editing and formatting might best be preserved in PowerPoint itself.
In summary, Microsoft PowerPoint is the most common and fully featured program to open .pptx files.
