Sumatra PDF is a slim, free, open-source PDF reader for Windows. Portable out of the box. Sumatra has a minimalistic design. Simplicity has a higher priority than a lot of features.

IMHO _THE BEST_ PDF reader, lean, mean and just does the job it is designed to. This is good software.

Oh red! Oh Yellow!
WTF is wrong with white and gray? I second ballyhairs on that.
But still, lite and free.

My favorite PDF viewer. it also opens extremely complicated electronic schematics with no problems. Brilliant.

Red with white spots?

I think the function of a reader is to be "basic". To let you *read* something quickly and efficiently as the name says - "reader". ;) So I find it absolutely fantastic and it loads instantly the PDF I want to read, it scrolls fast to the page I want to read. What else do you need? This is perfect and I'm afraid the unnecessary features from bored users who don't have to read a hundred of PDFs per day would make it slow as they made Adobe Reader slow and lately even my favourite PDF reader before this one - Foxit Reader. The only feature that is also required is copy and paste text or a picture... and that's it. What would you like it to do? To have painting tools or play video? ffs... it's a READER.

I wrote a review in "normal not-optimized" official build, but I've tried this one x64 optimized. Crashes when I'll go to "change language" in menu.

Appart from that, it is _very_ basic PDF reader. Sooo many features are lacking that it is not even funny.
