Screenshots showing Microsoft’s upcoming browser — codenamed Project Spartan — are out on the Web today.

The screenshots, with Chinese text, were first posted on the Chinese site ITHome. The Project Spartan browser is part of the Windows 10 OS, and was first previewed by Microsoft last month.

A Microsoft partner can have access to the latest Build 10009 of Windows 10 Technical Preview and the accompanying browser, which is apparently how the screenshots emerged.

Browser features shown in the images include a favorites menu, a reading list, and reading mode for long articles and PDFs, all of which have already been previewed by Microsoft. The browser is also scheduled to have Cortana integration and the ability to annotate web pages, among other features.
