The mobile operating system formerly known as Android P has officially landed. Contrary to leaked reports the OS is available for installation right now. Here's what you need to know.

Vista was bad. Coming five years after XP, it was heavily anticipated by Windows users who were impatiently awaiting something interesting from Microsoft as Apple's star was on the rise. Yet when the OS dropped publicly in January 2007, it was immediately reviled by, well, everyone (except our expert reviewers).

Apple showed off a raft of new features for the Mac, Apple Watch and iPhone at Tuesday's WWDC keynote. So many that the company breezed through most announcements and still talked for over two hours. I've had a chance to dive deeper into some of the announcements and pull out my favourite features, coming soon to a device near you.

Android P is here, for those who want it, with a compatible device and the patience to put up with a few extra bugs and crashes. We've been playing around with the beta OS on a Pixel 2, and these are the most promising features we've come across so far - including a few hidden goodies Google hasn't mentioned yet.

Installing updates on Windows has always been a pain. Not only does Microsoft seem hellbent on forcing users to update their machines whether they want to or not - including in prior versions of Windows 10 a nightmare "feature" that forcibly seized control of users' systems to start the installation process - the process is infamously slow.

The combination of these factors can make updating a Windows machine feel less like a minor but necessary inconvenience than a suddenly imposed tug-of-war for control of a computer. Fortunately, Microsoft is now mulling ways to make the process less painful.

For those who missed the memo, the first developer preview of Android P is now available. If you're keen to get Google's latest operating system on your smartphone right now, here's what you need to know.

The Google Assistant, the very best part of the Google Pixel and any other Android phone worth its salt, is now on iOS. If you're not a fan of Siri for whatever reason, this is Good News.

After being made available to developers back in March, and then more broadly through a public beta in May, the eighth major release of the Android operating system finally arrives today with Google revealing that the mysterious "O" actually stands for Oreo: A sandwich cookie suffering from a terrible identity crisis over the past few years.

I recently purchased an Android phone because my iPhone is getting old and I can't afford a new one. I'm wondering if you have any suggestions for porting everything across (contacts, music, apps, etc)? Preferably as quickly and seamlessly as possible!

Having guided you through the not-all-that-straightforward process of switching from Android to iOS, we're back to tell you how to go in the opposite direction. (Make your mind up will you?) Going from Apple-powered devices to Google's platform is either ridiculously easy or rather taxing, depending on your current setup.

The recently revealed "Android O" may not have knocked it out of the park for Google, but there is a nifty feature coming to the upgraded platform that will appeal in particular to mobile gamers -- graphic driver updates independent of full OS ones.

And in a week where the world is grappling with the consequences of just how vulnerable computers are is this joyous nugget of news: more Australians are using Windows XP than Windows 8.1, even though support for the former was officially canned years ago.

Google Chrome has become so good that when it comes to affordable, quality laptops, it's a better buy than a cheap Windows device. So Microsoft needs a lightweight OS to compete, and it's really hoping that the education-focused Windows 10 S will be that OS.

Today, Apple released a new upgrade to its MacOS operating system, dubbed Sierra. Like previous upgrades, MacOS Sierra is a free download for Mac users. It comes with a host of useful improvements including in-built Siri functionality, a universal clipboard, integrated Apple Pay and automatic iCloud uploads. Intrigued? Here's everything you need to know about the new OS.

MacOS Sierra is finally out of beta -- which means you can download the final version for free from the Apple Store. Get it here.

Last week, Google released Android Nougat for Nexus owners. It comes with some sweet new headlining features like multi-window support and bundled notifications. After digging into the developer preview we found even more treats that you might’ve missed.

This week marks one year since the launch of what is arguably Microsoft’s most ambitious – and possibly most controversial – operating system: Windows 10. Windows 10 represents a fundamentally different approach compared to the earlier versions of Windows that many of us have used, such as the highly popular Windows 7. A year after its launch, it continues to evolve and improve upon its predecessor. However, the privacy concerns still haven't gone away.

Still haven't upgraded your Windows 7 or Windows 8.1 device to Microsoft's latest OS? You might want to pull your finger out asap. On July 29, the free upgrade will no longer be offered. We take a look at what you should consider before upgrading.

Dear Lifehacker, I'm trying to toss up whether it's worth upgrading my laptop from windows 8.1 to Windows 10. I've heard mixed reviews and don't want to make the wrong decision! Should I take the plunge? Any assistance would be greatly appreciated.
