Microsoft confirms Windows 10 source leak was from Shared Source initiative

A small portion of the Windows 10 source code has been leaked. It contains files that are relevant to Windows USB, storage, and Wi-Fi drivers, though Microsoft has confirmed that the leak has come from its Shared Source initiative which is most commonly used by its partners and OEMs.

Microsoft has had to deal with several leaks of its operating system over the years and has at times been rather aggressive in defending it and chasing down those who leaked it. However, it has mitigated much of that with Windows 10 by opting for a regular release of new features and builds through its Insider program. But it’s not a foolproof system.

This latest leak appeared on the Beta Archive site, which hosts archived builds of Windows operating system for donating members. The site has now reportedly removed the leaked source code, though not because of Microsoft intervention in any way. It claimed that it had removed the file “under [its] own decision,” as per The Verge.

The leak totaled some 1.2GB of files and was said to be mostly made up of Windows 10 drivers. It did, however, also contain the Windows 10 Mobile Adaptation Kit, some Windows 10 Creators Update builds and some ARM-based versions of the operating system.

While leaks are always cause for concern for companies, this one will be more embarrassing for Microsoft than damaging, since it was code that was already available to partners and enterprises through its Shared Source initiative. No doubt Microsoft will still be keen to sniff out the source of the leak and make sure that they are unable to gain such access again, but it hasn’t commented on any measures it has put in place since the news broke.

Although far from a confirmed link, this leak appeared online a mere day after two men were arrested in the United Kingdom for allegedly hacking into Microsoft’s own network. Verge reports that they were said to be involved with accessing and collecting Windows 10 builds and one of them donated to the Beta Archive site.

In the past Microsoft has faced leaks from within. In 2012, a leak of a Windows 8 build came from one of its own employees.

Ranking all 12 versions of Windows, from worst to best
Windows 7 desktop.

You can tell a person's age by which version of Windows is their favorite. I have fond memories of XP and Windows 98 SE, so you can take a guess at mine, but I have colleagues who are much more enamored with Windows 7 or Windows 95. We all have something disparaging to say about Windows 8 though, and the less said about Windows Vista the better.

Ranking the different versions of Windows is about more than what era of computing you grew up in, though. There are some very serious duds in Microsoft's back catalog, just as there are a few wins too. With rumors about Windows 12 swirling, it's worth looking back at some of all the previous versions, ranked from the absolute worst to the very best.

Microsoft teases design overhaul of major Windows 11 app
Windows 11 set up on a computer.

Microsoft teased a design overhaul that is coming to the Windows 11 File Explorer app in a future update at its Build developer conference this week.

The new File Explorer design is based on WinUI 3 and will modernize the app's folders, sidebar, address bar, and search bar to be more in tune with the overall Windows 11 style. This will bring to File Explorer a look and feel with more rounded and blurred designs, as well as mouse and touch optimizations, Windows Central noted.
