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).
Key and Key ID. When you package a file, you use a key. A key is a piece of data used in the encryption algorithms that protect the content. There are two parts to each key: a license key seed and a key ID (often abbreviated as KID). The key ID is public, and is stored in the file header as a way to identify the key required to decrypt the file.
