SumatraPDF
Download from the vendor www.sumatrapdfreader.org

A tiny and very fast PDF reader for Windows that opens heavy drawings and specifications instantly. It also reads ePub, DjVu and XPS, and there is a portable version that needs no installation. Good for anyone who only needs to read and print, without a heavy editor.
