Adobe Acrobat Reader has always seemed like a bloated, laggy piece of software that takes far too long to launch. I have found the perfect alternative.

Sumatra PDF is “a slim, free, open-source PDF viewer for Windows”. Sumatra PDF is just one file and has no external dependencies so it can even run off a USB drive. The best thing about it is how fast it loads – it’s like Notepad for .pdf files.
