DebugView 4.81
Reveal hidden application messages that could help to troubleshoot your PC problems

DebugView is a useful troubleshooting tool that can display interesting status messages from your applications, perhaps revealing problems or issues that you never knew you had.

The program works by displaying messages sent to the Debug device, something occasionally used by developers to keep track of exactly what their creations are doing. These are generally only intended for their own low-level troubleshooting use, and can be very complicated and technical - there's no guarantee you'll understand them, or that you'll see any at all (most programs don't use the Debug device during normal operations). However, DebugView is so easy to use - you just launch it, run your system as normal and watch the program for occasional status messages - that it may be worth giving it a try.

If you do find DebugView displays a few interesting messages then you'll see that there's no immediately obvious way to see which application originated them. But the clue is in the value at the beginning of the "Debug Print" column. If this is a smallish number, like [4128], then it's a Process ID; press Ctrl+Alt+Shift to launch Task Manager, click the Processes tab and browse the PID column to see where the message came from. (There's no PID column? Click View > Select Columns and check PID..)

There are various other settings you might like to configure. We like to click Options > Clock Time to display a time for each message, for instance. And unusually for a Sysinternals tool, it actually comes with a reasonably complete Help file - press [F1] for details on other things that the program can do.

Please note, one of the first things you might notice in the documentation is a latest date of 2004, and no mention of working on anything older than Windows XP. We've used DebugView on Windows Vista and 7 and it still seems to work just as we'd expect, though, so don't worry about trying it on a more up-to-date system.

DebugView 4.79 fixes an incompatibility with Windows XP 32-bit that was introduced in the v4.78 release.


Most of the time DebugView doesn't tell you anything useful. Just occasionally, though, it'll provide essential information that you can't easily get in any other way, and for that reason the program deserves a place in everyone's troubleshooting toolkit

WhatsApp Messenger 2.12.11

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 2.12.11 brings:

• Links that you share or receive will now include a rich preview. When sending a link, you have the option to not include a rich preview.
• Additional 3D Touch features: You can now quickly Peek and Pop chats.
• Redesigned Settings tab. 
• You can now view all your starred messages across all your chats in Settings — Starred Messages.
