One-hundred and thirty-nine in a series. Welcome to this week's overview of the best apps and games released for Windows in the past seven days.

More than 14 million devices are running Windows 10 after the first day of release. We have covered the launch of the new operating system here on Betanews extensively and if you missed it, check out our Windows 10 topic to read up on that.

Most of the laptops you can buy come with Windows pre-installed. Obviously the latest batch have Windows 10 on them, with more being announced daily. If you prefer Linux you can either replace Microsoft's operating system with your distro of choice, or set up a dual boot configuration.

Online retailer Ebuyer, however, offers Linux-minded consumers a third option with its range of HP ProBook notebooks that come with Ubuntu pre-installed. There are three models on offer: HP 255, HP 355, and HP 455.

Windows 10 is now officially available, and many of you want to run the new operating system on your PCs and tablets right away. And why not? There are lots of cool features to get excited about, like the new Start menu, Cortana, Action Center, multiple desktops, and Edge. And it is offered as a free upgrade, if you have a valid Windows 7 or Windows 8.1 license, which makes it even more attractive.

Obviously, those who are using Windows 7 or Windows 8.1 can upgrade straight to Windows 10. But, the same cannot be said about Windows XP or Windows Vista users, who have to perform a clean install. That being said, a clean install is always recommended when moving to a new version of Windows, as it allows you to have an untainted experience, devoid of any issues that can crop up as a result of an upgrade. Here is how you can make a clean install of Windows 10.

A lot of things have changed in Windows 10, not least the way in which updates are delivered. Now that Windows 10 has been officially released and is gradually spreading around the globe, more and more people are starting to discover that the latest version of Microsoft's operating system is using more bandwidth than expected.

Windows 10 uses a P2P-style system called Windows Update Delivery Optimization (WUDO) which means that once your computer has downloaded an update it can be shared to not only other computers on your network, but also other people online. While it makes sense to share updates to your own computers, you might well resent giving up your bandwidth to others. Thankfully, it's easy to disable internet-wide WUDO.

When you go into File Explorer in Windows 10 you’ll see a selection of your most frequently accessed folders, and 20 of the most recently opened files.

This is useful if you want quick access to content you’ve been using recently, but if you don’t want all of these links cluttering up File Explorer you can hide the view, or disable it entirely.

The security of mobile communications is of paramount importance to many people, but it is particularly high on the list of priorities for business and enterprise customers. Silent Circle is a company that caters to those concerned with privacy and security, billing its work as the 'world's first enterprise privacy platform'.

The company's original Blackphone generated some interest, and earlier in the year we learned about the follow-up -- the Blackphone 2. Kitted out with a customized version of Android, the security-focused handset is the latest addition to Android for Work, Google's own security-focused program.

All the news surrounding Windows 10 is focused primarily on desktop and tablet, with little mention of Windows 10 Mobile from any Microsoft executives.

Vice president of Operating Systems Joe Belfiore has finally updated us on Windows 10 Mobile, stating that the Insider program allowing Mi 4 owners to flash the operating system will be open to anyone.

You’re browsing with Chrome, and have found a great video. Ideally you’d watch it all, uninterrupted, but there’s other work to do, and so you have to resize all your various windows to fit.

ScreenOut is a Chrome extension which gives you another option. Click an address bar button and the video opens in a floating, always-on-top pane. Then you can switch to some other application while still watching the clip.

Today marked a major milestone for mobile gaming studio Rovio. The Finland-based company is releasing it's latest version of the Angry Birds, this one aptly named Angry Birds 2. It follows up on the success of many predecessors, from the original to Space, Star Wars and more.

Like all previous versions, it's the tried and true "birds versus pigs" formula. There are a few strange things about it. For one, early levels are intent on telling you where to aim. For another, some levels force you to choose a different bird, You have no choice -- you can't fire until you've done it.

Windows 8 was a disaster. While I learned to love it, I'll concede that the majority of consumers apparently disliked it. For Microsoft to wash the bitter Windows 8 taste out of consumers' mouths, it would need to deliver an amazing new operating system. Can Windows 10 be the success that Microsoft needs it to be?

Yes. In fact, it already is. After a mere 24 hours of being publicly available, there are already 14 million computers running the operating system. While this number includes the computers from the Windows Insider program, it is impressive nonetheless. Keep in mind, this number is going to explode as time marches on. The first 24 hours of Windows 10 has been magical, and Microsoft is sharing the details.

Do you speak a foreign language? If not then Google Translate becomes your friend while travelling and today it's getting a bit better. Actually a lot better, going from seven languages to 27, which triples the amount it could handle -- okay that math is slightly off, but it's close enough.

Google announces the update to the app, which can be pointed at a foreign language and read the words in your native tongue. That's pretty essential for traveling. While it's good to know the language in any nation you're visiting, it's not always possible.

When it comes to web browsers, I use many. Firefox is my go-to most of the time, but I also like Google Chrome and Microsoft's newly-released Edge. Mozilla's browser is extremely important to me, as I feel the world needs a truly open-source web browser. With that said, Firefox has been lagging behind lately and disappointing its core. The company only recently started developing a 64 bit Windows variant again -- it is insane that development stalled no matter what argument it gives. Worst of all, Mozilla started bundling the Pocket service in the browser. The service isn't bad, but it shouldn't be bundled.

Today, Mozilla chooses to whine about browser choice in Windows 10. Chris Beard, Mozilla CEO, pens an open letter to Satya Nadella (in full below), in which he argues that Windows 10 takes away a user's choice by "design". While I can understand his point, it is misguided and he comes off as petty and desperate. Do you agree?

In an impromptu Q&A on Twitter, Microsoft's Joe Belfiore has revealed more about how Continuum will work on Windows 10 for Phones. He started off by saying that it is a very high-end feature and will require new hardware as it uses dual screens.

Continuum is part of Microsoft's drive to make a uniform experience for Windows 10 users across a range of different devices -- from desktops and laptops, to tablets and smartphones. Belfiore shared pictures of a Xiaomi Mi4 showing how Continuum allows windows to be moved from a desktop to mobile display, giving a tantalizing glimpse of what's to come.

We know that Windows 10 is the last version of Windows ever -- and this is really another way of saying that Windows will never be finished. Over the coming weeks, months, and years, we can expect to see a near-endless stream of updates to the operating system.

But while a trickle of updates was anticipated, few would have expected that a huge update would be just around the corner. Despite having launched just 24 hours ago, it seems as though the first big update to Windows 10 -- and it's shaping up to be a huge one -- is already looming on the horizon. Windows 10 Service Release 1 (SR1) could be released as early as next week!

Nokia’s event in Los Angeles wasn’t a smartphone, but instead a 360-degree film camera for virtual reality projects. Named OZO, it is intended for Hollywood and other video makers who intend to use virtual reality in the future.

The eight sensors that cover the spherical camera will collect film in 360-degrees, with playback stitched together within minutes. Nokia claims this is the first of its kind, with playback through VR normally taking hours in post production.
