To view a PDF file after using the Win2PDF Print to PDF instead of the Microsoft Print to PDF feature, just select the 'View file' option on the Win2PDF file save window.
When you save the PDF file, the file will automatically be opened with your default PDF viewer application, which is typically the new Microsoft Edge browser for Windows 11. Alternately, it may be the Adobe Reader software if that has been installed and configured as the default PDF viewer.
