Portable Update
Install Windows updates without an internet connection

Portable Update is a free (for personal use) tool for updating Windows computers which don't have an internet connection, or where the connection is slow, or where you regularly need to update systems and don't want to have to download the files every single time.

The program is so small (a 195KB download) that we wondered if there was some mistake, but no - this is all you need. Just unzip it to a USB key.

Run Portable Update on a PC which is connected to the internet and it downloads the Windows components it needs. We found this connection failed a few times with no obvious explanation, but after several retries it worked and the main program appeared.

Once you're set up, Portable Update can be used to scan disconnected PCs to find their installed updates and whatever they need.

Run the program somewhere with an internet connection and it'll download those updates into its own local cache.

Take the USB key back to the offline computer and you're able to install whatever updates it needs. And because the updates are cached, there's no need to go through the Download phase again, so if you reinstall Windows the following week, or buy a new PC, you can update those systems as well in a click or two.


The program is sometimes awkward to use, but at its core Portable Update does a good job of caching Windows updates to make them available offline

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.
