There are 2 pints in 1 quart, so there will be 3 pints in 1 and 1/2 quarts.
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).
A ' keyfile' (or key-file) is a file on a computer which contains encryption or license keys. A common use is web server software running secure socket layer (SSL) protocols. Server-specific keys issued by trusted authorities are merged into the keyfile along with the trusted root certificates. By this method keys can be updated without recompiling software or rebooting the server.
