It's a few days late for Prime Day, but Microsoft’s Edge browser now has an Amazon extension for your shopping convenience. It’s one of the last remaining features to be added to Windows 10 as its Anniversary Update draws closer to its “final,” shipping code.

Microsoft released Build 14390 for both PC and Mobile to Windows Insiders in the Fast Ring on Friday, with an emphasis on bug fixes. The one exception is the new Amazon extension for Edge, bringing the number of available Edge extensions to 13.

“Amazon Assistant helps you make better decisions wherever you shop online by giving you access to Deal of the Day, Product Comparison, Wish List, and Shortcuts to your favorite Amazon destinations,” according to Microsoft's published description of the extension.

More important, however, is the imminence of Microsoft's “final” code. Last year, Microsoft released its “shipping” build of Windows 10 to Insiders about two weeks before the OS was released at the end of July. The Anniversary Update's scheduled release date of August 2, 2016 is just about two weeks away. It's not clear whether Microsoft feels it’s necessary to give hardware makers time to test AU before it's pushed live, but if so, that would have to happen very soon.

In any event, Microsoft has listed few issues that Insiders need to concern themselves with. On the PC, the only bug listed includes a scenario where a user tries to boot Windows Server 2016 Tech Preview 5 virtual machines with Secure Boot enabled. Mobile users may have to enter a PIN twice when trying to pay using the Wallet app, and there are some intermittent glitches with the Voice Recorder functionality.

“Team, we’re getting down to the wire for the Anniversary Update release,” Dona Sarkar, the Insider chief for Microsoft, wrote in a blog post. “Please install this build and try things differently than usual this weekend. Check out some of the Quests in Feedback Hub. Hand the device to a friend and have them try it out. Install apps that are new to you. Send us all the feedback.”

Is this the final shipping code? Apparently not. Sarkar indicated that more Windows 10 Insider builds were in the works.

@win10fan haha, we have more builds coming. — Dona Sarkar (@donasarkar) July 15, 2016

Why this matters: We’re starting to see some scuttlebutt online that this might be the “final” build. It’s largely academic. As we get closer to launch, you’ll simply want to make sure you have everything in place for a major update: backing up crucial data, mainly. And if you’re still on Windows 7 or Windows 8.1, time’s running out for that free upgrade.
