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).
(The reason has to do with how the http headers are handled.) For example, x-amz-key would get stored as x-amz-meta-x-amz-key in S3 metadata. In contrast, x-amz-key would simply be stored as is (ie without the prefix) in an instruction file. All the keys described below are considered user metadata by the SDK.
