Sumatra PDF

Sumatra PDF is a lightweight PDF reader for Windows. Compared to Acrobat Reader and even Foxit Reader, Sumatra is simpler in its UI and faster to open. One of the coolest features is that when you open a PDF that you had opened before, it goes directly to the page and zoom level which you were at when you had closed it! I highly recommend Sumatra PDF as the primary PDF reader on Windows.
