If you are looking for another reason to purchase one of Microsoft's Windows 10 Mobile flagships, the software giant has just announced that it is now offering a free, one-year subscription to Office 365 Personal to Lumia 950 and Lumia 950 XL users.

The offer cannot only be redeemed by new customers, but also by existing users. There is one caveat though: it only applies to users in a select number of markets. Here is what you need to know.

When we look at how many PCs across the globe run Windows 10, we see Microsoft's latest operating system having a relatively modest usage share of around 10 percent. That is even though it is offered as a free upgrade from Windows 7 and Windows 8.1, both of which have remained more popular so far.

However, things are quite different in US, where a new IDC survey claims that nearly 30 percent of PC users have embraced Windows 10. That figure may not accurately represent the entire PC user base in the country, due to the nature of the survey, but it certainly can be seen as a vote of confidence for both Windows 10 and Microsoft.

Slack is the current communication darling for many small and medium businesses. The SMB-focused communication and collaboration solution is pretty simple -- it is similar to internet relay chat. Just like IRC, you join a channel and have text-based communications with other people. Where it differs, however, is its native ability to integrate with other tools. In other words, its potential is arguably greater than many competitors.

Today, Microsoft announces that it is enhancing Slack in a very special way. The Windows-maker releases a preview of Skype integration for the aforementioned communication solution. The team here at BetaNews uses Slack, so of course, I had to give it a go.

Continuum is one of the novel features that Microsoft has baked into Windows 10 Mobile. This enables users to essentially turn their smartphone into a more basic PC, using a Display Dock to connect the usual pieces of hardware -- a mouse, keyboard and monitor.

I say "more basic" because the device is severely limited in the number of apps it can display at the same time, as well as the type of apps that it can run: proper Windows software is out of the question with current hardware, only apps designed for Windows 10 Mobile are supported. But, now that Microsoft has introduced Continuum support in the Remote Desktop client preview, this feature is much more useful, and offers a more compelling argument for giving Windows 10 Mobile a chance.

Microsoft plans to give Windows 10 users another option to speed up the process of unlocking their PCs. The software giant has introduced an app that enables remote authentication using a Windows 10 Mobile device.

Called Microsoft Authenticator, the app is currently undergoing internal testing and it seems to be designed with enterprise users in mind. Microsoft likely wants to make it easier to deal with complex passwords, which are recommended for meeting certain security guidelines.

We all know that Microsoft wants as many people as possible to upgrade to Windows 10. The new OS is free for users of Windows 7 and 8.1, and the firm has the stated goal of getting it on a billion devices within 2-3 years.

To achieve this aim, Microsoft is pushing its new OS very aggressively, forcing it on to users, even if they have no desire to upgrade and have taken steps to actually prevent it.

Microsoft has been quick to brag about the adoption rate of Windows 10, proudly crowing every time another few million devices make the upgrade. We're currently sitting at around the 200 million mark (apparently), but the bulk of this number is made up of home users. Now Microsoft wants to encourage more businesses to make the jump from Windows 7 and Windows 8.1.

The next leg of the company's aggressive Windows 10 campaign is aimed squarely at SMBs who can now expect to be pestered by the "Get Windows 10" app in the same way as non-business users have for the last six months. Aware that taking the upgrade process out of the hands of IT admins might not go down too well, Microsoft is providing a way to opt out of these notifications.

Microsoft has announced new offerings regarding the recently acquired Revolution Analytics and its R language for statistical computing and predictive analytics.

Most importantly, its Revolution R Open is now called Microsoft R Open and will remain open-source and free for download.

Whether or not you attended or graduated from college, if you are a fan of basketball, you can totally enjoy March Madness. If you aren't familiar, this is a nickname for the NCAA Men's Division I Basketball Championship. Sixty eight teams will participate, but only one will be left standing at the end. Not only is it fun from a sports perspective, but for bracket competition and gambling purposes too.

While 68 teams sounds like a lot, there are far more colleges that won't even qualify for the tournament. My alma mater, Stony Brook University, has never qualified, but came close last year. Today, Microsoft announces a new website powered by Bing Predicts, which can predict the likelihood of a team participating in March Madness. Will your team make it?

It’s been a while since we’ve had any new Windows 10 preview builds, thanks to the holiday season, but Microsoft has at last pushed out a new build to the Fast ring. The software giant plans to make the Fast ring live up to its name this year with an accelerated release schedule.

In the future Microsoft’s criteria for releasing builds to the Fast ring will be much closer to its criteria for releasing them to its internal rings, which means new builds are likely to be buggier and suffer other issues. Build 11099, which is available for Insiders to download now, should be relatively stable however, as Microsoft has had a while to iron out any big problems.

Windows 10 seems to be building a core user base very nicely, just as Microsoft said when it revealed last week that it now runs on 200 million devices.

However, a study in the US suggests that most of those devices are in homes, not offices.
The study is based on US government data expressed as each Windows version’s percentage share of the total of Windows traffic reaching federal web sites.

Microsoft has launched an enhanced version of its Azure Site Recovery (ASR) targeted especially for VMware customers.

The ASR concept allows you to backup virtual machines into the Azure storage, update them and then run the VMs in Azure as a disaster recovery option. Microsoft charges $54 a month per VM instance stored in Azure, but doesn’t pay any compute or storage costs until you run the VM, which would make sense as it is only a file until the VM is spun up.

If you’re running Windows 10 you might want to head to Settings, Update & Security as Microsoft has just pushed out a cumulative update for its new OS.

This is an update for non-Windows Insiders, and brings the current build up to 10586.63.

Tonight is President Barack Obama's final State of the Union address. Regardless of your opinion of the man, or his policies, it is certainly monumental. After all, his being elected broke racial barriers; inspiring countless people of various backgrounds. More importantly, however, he has done many arguably positive things. While he has many more months in office, it is still a farewell of sorts.

Hopefully you will tune in for the historic broadcast, and if you do, you might consider choosing CNN or MSNBC. If you are Spanish-speaking, you should consider NBC Universo, and Telemundo too. Am I endorsing specific networks? Not really. I only suggest them because they will be leveraging Microsoft Pulse; something BetaNews readers should appreciate and enjoy.

If you’re still using Windows 8 it’s now time to upgrade because that operating system is about to get a whole lot less secure.

From today, January 12 2016, Microsoft will stop issuing security patches for its 3-year-old tiled OS, which will mean users will no longer be safe from newer threats.
