If you got a new computer for Christmas, chances are you're ready to get rid of the old one.

Whether you're donating it to a family member or friend, giving it to the local charity shop or selling it on Trade Me you'll want to make sure that none of your personal data falls into the wrong hands.

If you got a new personal computer for Christmas chances are it's running Windows 8.1.

The latest version of Windows is quite different to previous versions, and if you persevere with it you'll find Microsoft is right in saying that there are all kinds of new and exciting ways to do the things you love, like using apps and going online.

Want remote access to your Windows 8 or 8.1 PC? It's a lot simpler than you think, and if you've already got one of the Windows Phones already on the market all you need is an app.

The new style Start screen on Windows 8 and 8.1 personal computers is designed for touch sensitive screens which you can leave your sticky finger prints all over.

Microsoft skipped one when it previewed the latest version of Windows.

The software developer skipped releasing a Windows 9 personal computer operating system in favour of showing off Windows 10 which it released as an early technical preview for the personal computer on October 1.

The Lumia 930, which will be exclusively available through Vodafone New Zealand, comes with the Windows Phone 8.1 operating system and brings new experiences, as well as improvements, to the features that matter most like one-swipe notifications with Action Center, the super quick and intuitive Word Flow keyboard, customisable background images, and one of the best smartphone calendars on the market.
