## Summary of the Pull Request
This PR enables user to preview PDF files in the Explorer preview pane
and in Outlook.
**What is this about:**
Windows does not support out of the box experience for previewing PDF
files in the preview pane. Users need to install third-party software
like Adobe Acrobat reader. The PdfPreviewHandler module enbales the user
to preview PDF files.
**How does someone test / validate:**
Run the installer, open Explorer and select a PDF file, enable the
preview pane. Maybe need to remove third-party PDF software.
