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).
Here is how to back up a key (remember, a key is something like a folder): 1  Open Regedit and highlight the key. 2  Open the file menu and click Export. 3  A standard dialog box for saving files will open.  Save it someplace safe.
