Sumatra PDF
Use the lightweight Sumatra PDF to open PDF files

Think of PDF files and the first program that springs to mind is likely to be Adobe Reader. While this is a perfectly capable program, recent versions have come in for criticism for being large and slow, making them unsuitable for anyone running an older computer or a lower sec netbook.

SumatraPDF is a lightweight PDF reader which makes scant use of system resources and can even be run from a USB drive. The program offers faithful reproduction of PDF files and includes all of the features you would expect to find – a search facility, page navigation, zooming and more.

There are a variety of different views available and a rotate option is available for PDFs that have not been correctly configured. With the ability to save PDFs as text files and email files directly from within the programs, Sumatra PDF has all of the basic covered, but it does not offer some of the more advanced features found in alternative titles.

If you’re looking for a PDF reader that focuses on speed rather than features, Sumatra PDF is the tool for you. While the program could hardly be described as feature-packed, it is often the case that you simply need to open a PDF rather than doing anything more exotic with it – and Sumatra PDF is perfect for this.

Version 3.0 brings:

- Tabs! Enabled by default. Use Settings/Options... menu to go back to the old UI
- support table of contents and links in ebook UI
- add support for PalmDoc ebooks
- add support for displaying CB7 and CBT comic books (in addition to CBZ and CBR)
- add support for LZMA and PPMd compression in CBZ comic books
​- allow saving Comic Book files as PDF
​- swapped keybindings: F11 : Fullscreen mode, F5 : Presentation mode
​-  added a document measurement UI. Press 'm' to start. Keep pressing 'm' to change measurement units
​-  new advanced settings: FullPathInTitle, UseSysColors (no longer exposed through the Options dialog), UseTabs
​-  replaced non-free UnRAR with a free RAR extraction library.
​- deprecated browser plugin. We keep it if was installed in earlier version


If you are not too demanding of your PDF viewer and are looking for pure performance, Sumatra PDF is your ideal tool.

WhatsApp Messenger 2.12.7

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

Version 2.12.7 brings:

• Starred Messages
