Windows 10 Build 14390 has landed with a new extension and one fix for PC

Microsoft launched on Friday the latest build of Windows 10 for participants of the Windows Insider program Fast Ring. Released for PC and mobile, Build 14390 is another modest package that merely introduces improvements and fixes for the PC platform. The only notable news is that this build arrives alongside the launch of an official browser extension from Amazon for Microsoft Edge.

According to Dona Sarkar, the new browser extension is called Amazon Assistant, and it provides users quick access to Deal of the Day, Product Comparison, Universal Wish List, and shortcuts to their favorite spots on Amazon’s website. The extension can be added by hitting the “…” button, clicking on “Extensions,” and then “Get extensions from the Store.” Remember, extensions are turned off by default after installation.

Actually, you don’t have to be on this new build to grab the Amazon extension. It works on Build 14379 or higher, and resides with 13 other Microsoft Edge extensions sitting on Windows Store. These currently include AdBlock, AdBlock Plus, Evernote Web Clipper, LastPass, Mouse Gestures, Office Online, OneNote Web Clipper, Page Analyzer, Pin It Button, Reddit Enhancement Suite, Save To Pocket, and Translator For Microsoft Edge.

As for what’s improved and fixed on the PC, there’s only one noted change: a fix for error code 0x80004005. Previously, this error popped up when users enabled Developer Mode on the “For Developers” settings page if the PC isn’t using an EN-US language.

On the known issue front, Sarkar reiterates the major known issue that was explained with the release of the last build — the inability to boot Windows Server 2016 Tech Preview 5 virtual machines with Secure Boot enabled. Again, a fix for Tech Preview 5 is on the way, but unfortunately, changes to Windows Insider builds have arrived before the fix is released. Right now a temporary fix is to disable Secure Boot.

As with the Tech Preview 5 problem, Sarkar also reinstates the Start screen layout problem when reverting back to the retail version of Windows 10 Mobile (Build 10586) from a Windows 10 Mobile Insider preview build. This stems from a change Microsoft made to the backup format for Windows 10 Mobile devices in order to shrink the size of the backup as it’s stored on OneDrive.

“Your previous backup also gets overwritten. If you need to go back to Build 10586 temporarily, once you are on Build 10586 you should disable backup so it doesn’t overwrite the good backup from Windows 10 Mobile Insider Preview builds,” Sarkar explains.

Mobile devices also have two other listed issues. Voice Records refuses to show itself as an option for Call Recording, and Wallet users are still prompted to enter a PIN twice when using tap-to-pay from a locked phone. Thus, users can tap as usual once the PIN is entered twice and the device is unlocked.

Sarkar says that there are still quests published in Feedback Hub to take on, which the team will be performing this weekend. She suggests that Insiders “try things differently than usual” over the next several days, and send in feedback if they take a quest or two in their spare time. She also plans to launch an IoT project with Insiders next month, which she will start sketching out and throwing up on her Twitter account.

Windows 10 Anniversary Update will begin to roll out to customers on August 2.

You have one year to safely use Windows 10 before you’ll need to pay

Microsoft will be allowing consumers to join its Extended Security Updates (ESU) program for the first time next year, and it announced the program pricing today in a blog post. The official end-of-service date for Windows 10 is October 14, 2025, but by paying $30 to join the ESU program, you can receive an extra year of security updates. This will allow you to continue safely using Windows 10 until around October 2026, a full two years from now.

By the time support for Windows 10 ends, it will be almost exactly four years since Windows 11 launched and a decade since Windows 10 launched. It takes a lot of work to keep an operating system secure and running smoothly, which is why a company like Microsoft can't just endlessly support every version of Windows it's ever shipped. It would end up costing a lot more money than it made -- and that's not how businesses function.

There’s a scary new way to undo Windows security patches

Security patches for Windows are essential for keeping your PC safe from developing threats. But downgrade attacks are a way of sidestepping Microsoft's patches, and a security researcher set out to show just how fatal these can be.

SafeBreach security researcher Alon Leviev mentioned in a company blog post that they'd created something called the Windows Downdate tool as a proof-of concept. The tool crafts persistent and irreversible downgrades on Windows Server systems and Windows 10 and 11 components.

PC gamers still prefer Windows 10 over Windows 11

Windows 11 saw a decline in the latest Steam hardware and software survey for July 2024. According to Valve's data, gamers using Microsoft's newer operating system dropped below the 46% threshold. Currently, Windows 11 accounts for approximately 45.81% of all Windows users on Steam, marking a decrease of 0.82% from the previous month.

In contrast, Windows 10 experienced an increase of 0.74%, reaching a 50.16% share. Although gaming performance is generally similar on both operating systems, a recent test by Hardware Unboxed reveals that Windows 10 may offer better performance in certain titles due to the core isolation feature, where memory integrity is enabled by default on Windows 11.
