Two weeks ago, Microsoft released Insider Preview Build 14931 to the Fast ring. It wasn’t the most exciting of new builds, as it didn’t offer any new features as such, but focused instead on improvements and fixes.

Today, that build makes its way to the Slow ring. Improvements for PC include:

Two weeks ago, Microsoft finally removed its scummy Windows 10 nagware from Windows 7 and 8.1 systems. This came as a major relief to everyone who didn’t want to upgrade to the latest operating system, but who had been forced to weather a storm of increasingly sneaky tactics as the software giant pulled every trick possible to get as many users to upgrade before the free period expired.

With the nagware removed, users were no doubt hoping that would be the end of the matter, but it turns out that might not be the case after all.

September wasn’t a good month for Windows 10. After enjoying uninterrupted meteoric growth since launch, usage share for the new OS actually dropped off last month, according to the latest figures from NetMarketShare announced on Saturday.

That's not the only bad news for Microsoft either. Gamers, who typically prefer to be running the latest operating system, also turned their back on Windows 10 in September.

It was expected, that once Windows 10 stopped being free, upgrades would slow significantly. That turned out not to be the case last month when NetMarketShare’s usage figures showed it, rather surprisingly, to be business as usual. Growth in August was no different from growth in previous months, although I speculated it might have been buoyed by sales of new back to school PCs.

In September though, according to NetMarketShare, Windows 10 didn’t just show slower growth, it actually went into reverse gear and lost usage share. Yes, you read that right.

The Ignite conference in Atlanta might be keeping many Microsoft employees busy, but it hasn’t stopped developers working on the next big update of Windows 10.

A week after Build 14931 arrived on the Fast ring, Windows Insiders are today being treated to another new update -- Build 14936 for PC and Mobile.

Two months ago, Microsoft CEO Satya Nadella announced the software giant would be changing how it monitors the growth of Windows 10, tracking monthly active users -- rather than devices --  after it became clear slow sales of Windows Phones meant the new OS wouldn't hit the company's stated goal of one billion devices by mid-2018.

Today, at Ignite, however, Microsoft announced another devices milestone, saying the new OS is now running on 400 million devices. It’s a big number, but it does show that growth is slowing significantly, now that Windows 10 is no longer free.

One-hundred and ninety-nine in a series. Welcome to this week's overview of the best apps, games and extensions released for Windows 8.x and Windows 10 in the past seven days.

This week saw the release of a first batch of converted win32 applications like Kodi, Tweeten or PhotoScape X Pro  in Store.

Back in January, Microsoft announced Minecraft: Education Edition. Later, the company released an 'early access' version to some educators. At the time, some folks were dubious that a video game could serve as a legit tool in the classroom. With that said, Minecraft isn't really a video game in the traditional sense -- it can be viewed more as a virtual world. In theory, the platform could better engage young students when compared to, say, sitting in a dull classroom and staring at a chalkboard.

Whether Minecraft: Education Edition will be a success remains to be seen, but we will find out soon. You see, on November 1, the tool will leave 'early access' and become available to all educators. It will be sold, of course, on the Windows Store. It will cost $5 annually per user, but Microsoft promises price breaks for school districts that purchase certain licenses. In other words, larger districts can likely negotiate to pay less per user.

The Raspberry Pi is popular for three major reasons -- it is small, inexpensive, and doesn't consume a lot of electricity. This makes the board very popular for things like education, servers, IoT projects, and media playback. Unfortunately, as many consumers find out quickly, the Raspberry Pi computers are woefully underpowered for some needs. In other words, despite the low cost, it isn't necessarily a bargain.

Today, SolidRun announces an Intel Braswell-based MicroSoM. Unlike the ARM-powered Raspberry Pi, this is x86 compatible, meaning it can run full Windows 10. Plus, if you install a Linux distro, there will be far more packages available, such as Google Chrome, which is not available for Pi. Heck, it can probably serve as a respectable desktop. Even though it costs more than the Raspberry Pi, is it a better deal?

The EFF (Electronic Frontier Foundation) has already ripped into Microsoft and Windows 10 for "blatantly disregarding user choice and privacy", and now consumer group Which? says Microsoft "must act over Windows 10 woes" and "do better".

Which? says it has received well over 1,000 complaints about Windows 10, with PC users claiming the new OS has brought them nothing but problems.

A week ago, Microsoft rolled out its first really big new Windows 10 Insider Preview build since the Anniversary Update. As well as fixing a lot of problems, Build 14926 introduced some experimental new features, including the ability to "snooze" a tab in Microsoft Edge.

Today, Microsoft releases Build 14931 to the Fast ring, but unlike recent builds it’s only available for PC. Build 14926 introduced a couple of big problems for Mobile last week, so Microsoft has decided to hold off issuing a new build until they are fixed.

15 months ago, in an effort to make it as easy as possible to upgrade to its new operating system, Microsoft introduced a Get Windows 10 app for Windows 7 and 8.1 that allowed users to reserve their upgrade.

While this tool was innocuous enough to start with, it soon turned into something much more akin to malware, becoming harder and harder to kill, and employing all manner of scummy methods in an effort to trick users into installing Windows 10 against their wishes.

Are you into gaming and can't wait to get your hands on the latest titles? You've got a big one on the way and now you don't have to wait quite as long to at least get a look at what you're missing.

Today, Microsoft is releasing the first full-length trailer for Gears of War 4. It is narrated by John DiMaggio who you may recognize as the voice of Marcus Fenix from the game.

There is no place for bullying in the world. Schools around the country are teaching this important lesson. When one person is mean to another, that is very bad. When two people join forces to bully someone, it can be even worse -- it is hard to stand up for yourself when you are outnumbered.

When Microsoft ran mean-spirited advertisements against Apple's MacBook, my colleague Mark Wilson took umbrage, calling the ads 'childish and imbecilic'. Today, in an all-new ad, Huawei MateBook is joining the Surface Pro in the Apple-bashing. The personified versions of two Windows 10 tablets come across as bullies, belittling Apple's iPad Pro.

You don’t need a valid license to run a Windows 10 Insider Preview Build on your PC. Each build is time-limited, but a new version will be released before the previous one expires.

Provided you keep updating your system to the latest build, you’ll have no problems. However, if you’ve installed a preview build and not updated it -- hey, free Windows! -- Microsoft is about to flip a kill switch that will stop it working entirely.
