Microsoft continues to issue updates to Windows 10 as the firm prepares to deliver the Anniversary Update to over 350 million devices worldwide.
The company announced earlier this week that 2 August will be the official release day for the Windows 10 Anniversary Update, the second major upgrade to the operating system since its launch at the end of July last year.
Meanwhile, the year-long free upgrade period offered to people with valid Windows 7 or Windows 8.1 licences will draw to a close at the end of July, days before the firm starts to push out the Anniversary Update.
The latest Preview Build 14379 was made available overnight on the PC and Mobile platforms for testers in Microsoft's Windows Insider community signed up to Fast Ring releases.
As with many recent releases, Build 14379 comprises mostly bug fixes as the Windows team attempts to improve the overall quality of the Windows 10 code.
Among the fixes in this build are one for a problem where the Action Centre might crash after dismissing a large number of notifications on the PC, and one for the Mobile platform to address a minor fault where the images on live tiles displayed in an incorrect aspect ratio.
Microsoft also detailed some of the enhancements that will arrive in the Windows 10 Anniversary Update after 2 August.
These include additional security features, such as improvements to Windows Defender, the extension of the Windows Hello biometric log-in to apps and websites, and Windows Defender Advanced Threat Protection for enterprise customers.
The Anniversary Update will also introduce Windows Ink, bringing better support for pen input such as handwriting in Office, annotations in Microsoft Edge or drawing customised routes in Maps, Microsoft said.
Cortana now allows users to ask questions or set a reminder without unlocking their device, while the Microsoft Edge browser features power-saving improvements and officially introduces support for Edge Extensions, such as the recently announced Evernote add-on.
"We are committed to delivering continuous innovation to you, including features that bring Windows Ink and Cortana to the mainstream, a faster, more accessible and more power-efficient Microsoft Edge browser, advanced security features for consumers and enterprises, new gaming experiences, and new tools for the modern classroom," said Microsoft corporate vice president for the Windows and Devices Group Yusuf Mehdi.
Everyone already running Windows 10 will get these new features for free, Mehdi added, as part of Microsoft's Windows-as-a-service update strategy.
