Microsoft never sleeps. Even before the Windows 10 Creative Update was rolled out, the company began work on the next major update to Windows 10, code-named Redstone 3.
As it did with the Creators Update, Microsoft has been releasing public preview builds to members of Microsoft's Insider Program via a series of public preview builds.
What follows is a list of every preview build of Redstone 3, starting with the most recent. (Note: This covers only previews for the PC version of Windows 10, not the phone version.) For each build, we've included the date of its release and a link to Microsoft's announcement about it.
Note that we've kept the list of all the preview builds that let up to Creators Update, which are below the builds of Redstone 3.
Release date: May 17, 2017
This minor build includes several new features for the My People app. You can pin your favorite contacts to the taskbar and see emoji from your pinned contacts. Pinned contacts also display counters for messages you haven’t yet read from them. And you can now share files with contacts by dragging and dropping files onto pinned contacts, which creates an email message to the contact with the file attached.
The build also includes several minor changes to settings, notably the addition of a health section that pulls information from the Windows Defender Security Center, making it easier to see the overall health of your PC in a quick glance.
Beyond that are the usual assortment of minor changes, improvements and bug fixes, such as Windows Defender Security Center not flagging disabled drivers as issues.
Release date: May 11, 2017
The big news in this build is the release of Story Remix, a major upgrade for the Windows 10 Photos app. It lets you mix together photos, videos, music, transitions, inking and 3D objects to create “stories” -- essentially, screen shows on steroids. It does more than that, though: It also will create these stories itself, at your bidding. So, for example, you can click the Remix button for a collection of photos or videos, and Remix will put together a suitable soundtrack, transitions, and so on. You can then edit what Remix has done.
Story Remix uses what Microsoft says is “deep learning and AI” to tag people, places and things, so they're easier to find via search.
Beyond that, this release offers the usual assortment of minor changes, improvements and bug fixes, such as making the Settings app more stable so it doesn’t crash when navigating to Settings > Personalization > Lock screen.
Release date: May 4, 2017
This build features several improvements for Microsoft Edge’s PDF reader. The reader now lets you fill in PDF forms and annotate PDFs. The app's navigation has also been improved, and you can also finally rotate PDFs.
Edge also gets a security improvement: The Windows Defender Application Guard, which offers increased protection against malware and Zero Day attacks. There’s also a related change that anyone who has ever been confused about Cortana’s settings will be pleased to see: Cortana settings are now available in the Settings app, rather than separately.
This build also includes a variety of minor changes, improvements and bug fixes.
Release date: April 28, 2017
This build introduces a new feature called My People that Microsoft promised was on the way last October, but that was delayed until after the Creators Update. My People is a social app that lets you pin your favorite people to the taskbar, and makes it easy to contact them in a variety of ways, including the ability to share files and photos, chat, and include emojis. The app remembers the way you've shared with each person previously and uses that method each time afterwards, unless you decide to change it.
There are also a variety of minor changes, improvements and bug fixes for the OS, including the ability to disable the Night Light feature (which reduces the amount of blue light produced by your display).
Release date: April 19, 2017
This early build has few changes in it. A new feature introduces automatic checkpoints to Hyper-V for developers so that they can easily undo mistakes by being able to always revert to the last time they started a virtual machine. Power throttling, which can save up to 11% in CPU power consumption, has been turned on. There are also a variety of minor changes, improvements and bug fixes.
Release date: April 14, 2017
Because this is an extremely early build of the next upgrade to Windows, there are no noticeable new features. Microsoft has mainly worked on OneCore, which is the heart of the operating system that works not just on the PC version of Windows 10, but also on Windows 10 Mobile, Windows Server, Xbox 10, Windows 10 IoT and the HoloLens operating system. There are some very minor changes and bug fixes. The Narrator, which had been broken in the build 16170, now works, for example.
Release date: April 7, 2017
Well, that didn’t take long, did it? Even before the official rollout of Windows Creator Update, Microsoft released the first preview build update for the next upgrade to Windows 10, due out by the end of the year.
Given that it’s the earliest public build of the next upgrade, there’s very little new here, only the most minor of bug fixes, such as an update to the share icon in File Explorer. However, there are a number of known issues with the build. Narrator doesn’t work in it, for example, and some apps and games may crash. So if you decide to try it, proceed with caution.
Preview builds for Creators Updates
Release date: March 20, 2017
This build offers only two minor changes and bug fixes: one in which Edge would become unresponsive and another that affected language packs.
Release date: March 17, 2017
This build offers only a few minor changes and bug fixes, including one in which some VPN connections don’t show up in Network Connections.
Release date: March 16, 2017
This build offers only a few minor changes and bug fixes, including one in which Microsoft Edge would not launch several minutes after it crashed.
Release date: March 14, 2017
This build offers a few minor changes and bug fixes, including one that caused some Windows apps such as the Windows Store to fail to launch, and one in which people could not get to the Wi-Fi settings page.
Release date: March 10, 2017
This build offers only minor changes and bug fixes. There are ten fixes for Microsoft Edge, including one for circumstances in which touchpad and keyboard input periodically stops working for a few seconds at a time when using an Edge window.
For the first time, the Windows version number displayed is 1703, which likely indicates the next update to Windows -- called Creator’s Update -- is close to final. The version number usually indicates when the final build will be compiled, which in the case of “1703” would mean March 2017. If that’s the case here, it would mean that the Creator’s Update would likely be compiled some time this month.
It has been reported that the official availability date of the Creators Update will be April 11. Not uncommonly, it takes several weeks between when an update is compiled and when it’s generally available to the public, so the time frame seems right.
Release date: March 3, 2017
This build offers only very minor changes and fixes for bugs such as: LastPass password manager extension for Microsoft Edge sometimes failed to show autofill buttons; the mouse wheel would not work properly; some games minimized to the taskbar as soon as they were launched.
Release date: February 28, 2017
This build offers a variety of minor changes that will be released to the general public in the Creators Update, which is expected in April. Windows Defender Security Center has several modifications, including the addition of an icon in the notification area so you can easily see your protection status. Cortana now displays apps, files and websites that appeared in Microsoft Edge when you last used it. There are also a variety of small changes, improvements and bug fixes.
Release date: February 24, 2017
This minor build offers new animation for Cortana, a new animation for the Edge URL bar which shows when Flash content is being blocked, and a few minor improvements to Edge's ebook-reading capabilities. There are also various small changes, improvements and bug fixes.
Note: This build only works with PCs running 64-bit versions of Windows, not 32-bit versions.
Release date: February 8, 2017
The main feature of this minor build is the introduction of the Compact Overlay window feature, which lets developers write apps that display in a thumbnail above other windows so they're always visible --for example, for watching a video. The Windows 10 Movies & TV app and Skype Preview app will eventually make use of it. There’s also a new Share icon, and a variety of minor bug fixes and changes.
Release date: February 1, 2017
The main new feature in this minor build is braille support for the Narrator screen reader. There are also several small improvements and bug fixes. The build is aimed primarily at the upcoming Windows 10 Creators Update and is the primary build for the second Windows 10 Creator's Update Bug Bash, during which users and developers identify as many bugs as possible; it started on February 3 and will end on February 11.
Release date: January 27, 2017
This minor build focuses in large part on adding features to Xbox gaming. Included is the ability to broadcast your gaming play by streaming it over the internet, as well as a new Game Mode that optimizes your PC for gaming. Scott Henson, Xbox Partner Group Program Manager, has provided a list of all new gaming features on his blog. Even though this build is, to a great extent, targeted at gamers, Dona Sarkar, Software Engineer, Windows and Devices Group, noted in the announcement that, "This build does have some platform related bugs that will impact the ability to play popular games on your PC."
There are a variety of other minor changes, such as giving Microsoft Edge the ability to read e-books aloud, and being able to stop app and game download progress in the Action Center. There are also several small improvements and bug fixes.
Release date: January 19, 2017
This build adds a handful of minor new features, and fixes a variety of bugs, many of which have been pointed out by users in Microsoft’s Feedback Hub. With it, you can now buy e-books from the Windows Store and read them in Microsoft Edge. There’s also a new custom color option in the Color settings, the W-Fi settings have been simplified, and there is a new Storage setting for letting you automatically delete files you don’t need any longer.
Release date: January 12, 2017
This minor build focuses on several small improvements to the Edge browser. You can now share tabs with other apps on your PC; you can also more easily import favorites, browsing history and passwords from other browsers. Microsoft has updated the web notes feature so it uses Windows Ink, among other features.
There are also non-Edge improvements; for example, when you switch from one PC to another, Cortana will display (in the Action Center) links to the Edge websites and the SharePoint or OneDrive documents you most recently used on the original PC. There are several other small changes and a variety of bug fixes.
Release date: January 9, 2017
This build makes a fair number of changes to the Edge browser and adds a few tweaks to the overall interface.
Edge now features a useful tab preview bar that pops at the top of the screen when you click a small down arrow to the right of the + next to your tabs. You can then scroll through the tab preview bar by clicking an arrow on its right side, or by using a mousewheel, touchpad, or swiping on a touch screen.
Edge also gets two new buttons for managing tabs: one of them closes all your tabs; the other one thumbnails of the tabs you’ve closed and lets you restore them all, or each individually. Edge also blocks untrusted Flash content and gives you the choice of whether you play it or not. The Microsoft Edge changelog lists all the changes to Edge.
People who are fans of the Start menu will welcome a new feature that lets you group Start tiles into folders. This build also addresses a complaint that some people have had about windows resizing not being smooth enough -- according to Microsoft, it’s now smoother on both desktop applications and Windows apps.
The build also includes minor improvements to Windows Ink, Cortana, Windows Defender, accessibility features and the Settings app. And, as always, there are a variety of bug fixes.
Release date: December 7
