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).
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace\. You can see in the above screen shot that there are several registry keys with convoluted names. Most of them are mapped to one of those folders you see in the explorer Window.o remove the folders from the explorer window, simply delete the corresponding registry key using the information provided above. Thatâs pretty much all there is to it. Of course, if you are not comfortable hacking around in the registry you can just run one of the handy registry files we have created for you.
