Hi Niki, I understand that Windows Reader is the default Viewer for PDF files. What I was asking was how this was stored in the registry. The key HKEY_CLASSES_ROOT\.pdf key has (Default) = AcroExch.Document (if you have Acrobat Reader installed). In Windows 8 the .pdf key has (Default) =  (blank).
The Windows key is a standard key on most keyboards on computers built to use a Windows operating system. It is labeled with a Windows logo, and is usually placed between the Ctrl and Alt keys on the left side of the keyboard; there may be a second identical key on the right side as well. Pressing Win (the Windows key) on its own will do the following: Windows 10 and 7: Bring up the Start menu.
