Registry Compressor 1.1.0
A quick and easy Registry defragmenter

Launch Windows, open a folder or file, install, remove or run a program - just about everything you do on a PC results in Windows writing to the Registry. And over time that means the Registry files will grow, as they contain more and more "slack space", gaps where old entries used to be.

This isn't particularly harmful, but it does waste a little memory and hard drive space. And so you might like to try Registry Compressor, a small and simple tool which can defragment your Registry, removing this slack space (nothing else - this isn't a Registry cleaner) and cutting the files down to size.

We've no reason to believe this is dangerous - it's a simple enough process, and worked fine on our test PC - but plainly if there is a problem and your Registry is corrupted, then it will be a disaster. So only run Registry Compressor on a system which has been fully backed up. And close down all running programs before you launch it, too.

With that done, launch Registry Compressor, click Analyze, and after a few seconds it'll present some figures on how bloated your Registry files might be. On our test PC, some of the smaller hives were anything up to 9 times larger than they needed to be, but overall this wasn't a major problem: the total size of our Registry was currently 172MB, and Registry Compressor claimed it could reduce this to 168.99MB, a 1.75% saving.

If you'd like to make this saving on your PC, simply click "Compress", and after a second or two (it's very quick) the program will tell you it's done, and recommend you reboot. We did so, checked again and our fragmentation had dropped to 0.1MB, or about 0.06%.

Is this worthwhile? We saw no apparent performance difference. Still, when you're optimising your PC then all these smaller tweaks can add up, and it's so quick and easy to use that you might want to give Registry Compressor a try. Just be sure you use it with care; backup your system and close programs beforehand, and reboot your system immediately afterwards.

Version 1.1.0:

- Now supports the command line /silent or /s and can now also reboot the system if you want it to.
- Code changes and cleanup, program is now 330kb smaller.


Registry fragmentation isn't a major PC performance issue, but it can waste a little RAM and drive space, and Registry Compressor recovers this with ease

WhatsApp Messenger 2.16.11

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.

What's new in 2.16.11?

 - Due to a bug in iOS 10, your notification sounds may not properly play until you restart your iPhone (press and hold the power and home buttons for 10 seconds).
- In groups, you can now mention specific people to get their attention by typing the @ symbol and choosing someone from the picker. 
- When forwarding messages, you can now send to multiple chats at once 
- Ask Siri to send WhatsApp messages or place WhatsApp calls (iOS 10+) 
- Answer WhatsApp calls right from your lock screen, just like a standard phone call (iOS 10+) 
- A new Widget lets you quickly jump to a recent chat or see which chats have unread messages (iOS 10+)
