The launch of a major Windows 10 update isn’t the end of a process. it’s really just the beginning. As soon as one of Microsoft’s twice-yearly feature updates is released, the company quickly gets to work on improving it by fixing bugs, releasing security patches, and occasionally adding new features.

Here we’ve summarized what you need to know about every Windows 10 update being released to the public. First come updates to the currently shipping version of Windows 10 — version 1909, known as the November 2019 Update — with the most recent updates on top.

(Note that Microsoft has not yet begun actively pushing 1909 to users. You can seek out and install the release on your PC, but why rush things? In fact, we recommend keeping 1909 off your machine for now to avoid any bugs that may crop up with the new release.)

Next come updates to version 1903, known as the May 2019 Update; version 1809, known as the October 2018 Update; version 1803, the April 2018 Update; version 1709, the Fall Creators Update; and finally version 1703, the Creators Update. For each build, we’ve included the date of its initial release and a link to Microsoft’s announcement about it.

Note: If you’re looking for information about Insider Program previews for upcoming feature releases of Windows 10, see “Windows 10 Redstone: A guide to the builds.” And if you’re still using an earlier version of Windows, see the Microsoft support site for details about updates to Windows 7, Windows 8.1 and Windows 10 version 1607 / Windows Server 2016.

Windows 10 November 2019 Update (version 1909)

Release date: Nov. 12, 2019

Version 1909, called the Windows 10 November 2019 Update, is the most recent update to Windows 10. There are very few new features in this update, making it more like a service pack of old than a feature update. At this point it’s not clear whether in the future there will be one full-featured update and one service-pack-like update per year or whether Microsoft will go back to its two-feature-updates-a-year schedule. For more details, see “What we know so far about the unusual Windows 10 1909” and “5 unanswered questions about Windows 10 1909.”

Here’s a quick summary of what’s new for users in 1909.

• It lets you create calendar events straight from the taskbar. To do it, click the time on the taskbar and you’ll open the Calendar view. Now click a date and time, then type the event’s name into the text box. You’ll also be able to choose the date, time and location.
• When you type a search into the search box, it will now search through files in your OneDrive account as well as on your PC. Also, as you type, a drop-down menu with suggested files appears. Click a file to open it.
• Voice assistants in addition to Cortana, including Amazon’s Alexa, will be able to run on Windows 10’s lock screen.
• Under-the-hood improvements should speed up the performance of some PCs, as well as increase the battery life in some laptops.
• The Start Menu has gotten minor tweaks. When you hover over items in the navigation pane on the left side of the menu, the items clearly show what you’re about to click.

What IT needs to know: The following features in 1909 are of note for IT staff.

• Windows containers no longer need to have their host and container versions match. That requirement restricted Windows from supporting mixed-version container pod scenarios. Previously, containers from older versions of Windows 10 couldn’t be run on newer versions of Windows 10. In this update, it’s possible, so that a container made using 1903, for example, can be run on 1909.
• Windows Defender Credential Guard, which protects enterprise users’ logins and credentials against theft, is now available for ARM64 devices. Some Windows 10 convertible PCs use ARM64.
• Enterprises can now use Microsoft’s Intune enterprise mobility management (EMM) service to allow devices running Windows 10 in S mode to install and run Win32 (desktop) apps. Before this, S Mode only allowed devices to run apps from the Microsoft Store. Microsoft Store apps don’t run on the desktop.
• The security of BitLocker encryption has been improved. Whenever BitLocker is used to encrypt a device, a recovery key is created, but before this security improvement, it was possible for an unauthorized user to get access to the recovery key and decrypt the device. Now, PCs have additional security if a key is exposed. Here’s how Microsoft explains the change: “Key-rolling or Key-rotation feature enables secure rolling of Recovery passwords on MDM managed AAD devices upon on demand request from Microsoft Intune/MDM tools or upon every time recovery password is used to unlock the BitLocker protected drive.”

Updates to the May 2019 Update (version 1903)

Note: Starting in November 2019, Microsoft began issuing identical updates for Windows 10 versions 1903 and 1909. The updates above under “Windows 10 November 2019 Update (version 1909)” are the same as those delivered to version 1903.

KB4522355 (OS Build 18362.449)

Release date: October 24, 2019

This update fixes a wide variety of minor bugs, including one that prevented Microsoft Narrator from working in certain touch mode scenarios; another that prevented windows from being shrunk in some cases; and another that caused the Start menu, the Cortana Search bar, Tray icons, or Microsoft Edge to stop responding in certain scenarios after installing a monthly update.

There are no known issues in this update.

KB4517389 (OS Build 18362.418)

Release date: October 8, 2019

This update fixes a variety of security issues in Windows Shell, Internet Explorer, Microsoft Edge, Windows App Platform and Frameworks, Windows Cryptography, Windows Authentication, Windows Storage and Filesystems, Windows Kernel, Microsoft Scripting Engine, and Windows Server. For details, see Microsoft’s Security Update Guide. It also addresses an issue in security bulletin CVE-2019-1318 that may cause client or server computers that don’t support Extended Master Secret (EMS) RFC 7627 to have increased connection latency and CPU utilization. In addition, it fixes an issue with applications and printer drivers that utilize the Windows JavaScript engine (jscript.dll) for processing print jobs.

There are no known issues in this update.

What IT needs to know: Because this is a security update, it should be applied relatively soon. Over the next few weeks, check for reports about problematic issues, and if all seems well, apply the update.

Windows 10 May 2019 Update (version 1903)

Release date: May 21, 2019

Version 1903, called the Windows 10 May 2019 Update, is the feature update that preceded the November 2019 Update. Here’s a quick summary of what’s new for users in it. (For more details, see our full review.)

• Windows 10 Home and Pro users can now control whether to install the twice-yearly feature updates like the Windows 10 May 2019 Update via a new “Download and install now” option. However, when users’ current version of Windows reaches what Microsoft calls “end of service” — the point at which Microsoft no longer supports it — Windows 10 will install the latest feature update automatically. End of service is typically 18 months after a Windows 10 feature update is released.
• Windows 10 users can pause any minor Windows updates that Microsoft issues in between the big feature updates for up to 35 days.
• Cortana and the search box have been separated. To perform a Cortana search, you can say “Hey Cortana” and speak your search, click the Cortana icon to the right of the search box and speak, or press the Windows key + C and speak. All other searches are done by Windows Search.
• You can now use search to find files in any location on your PC, not just in default libraries and folders like OneDrive, Documents, Downloads, Music, Pictures, Videos, and Desktop. However, that requires indexing, which reduces laptop battery life and could slow down PC performance.
• You can uninstall more built-in apps than previously, including 3D Viewer (previously called Mixed Reality Viewer), Calculator, Calendar, Groove Music, Mail, Movies & TV, Paint 3D, Snip & Sketch, Sticky Notes, and Voice Recorder.

What IT needs to know: The Professional and Enterprise versions of Windows 10 get a new security tool called Windows Sandbox. It lets you test out software and websites in their own containers, so that if they’re dangerous, they can’t get to Windows 10 itself. Close the sandbox, and the software or website vanishes.

IT administrators can also extend the safety features of Windows Defender Application Guard beyond Edge via browser extensions for Chrome and Firefox and an app from the Microsoft store. When users browse to an untrusted site in Chrome or Firefox, the site will open in Edge, inside a virtual machine using Windows Defender Application Guard.

When Apple unveiled the iPhone 8 and the iPhone X in September 2017, the company also announced a universal wireless charging mat called AirPower. That was the year the iPhone finally got support for wireless charging.

But AirPower was meant to be more than a “dumb” wireless charger requiring you to place a product in the exact right spot. It could also recharge multiple devices wirelessly at the same time, including the iPhone, Apple Watch, and AirPods.

However, the accessory wasn’t ready in early 2018, and then Apple went dark. Finally, in March 2019, the AirPower was canceled. The problem with the AirPower, according to reports, was it was overheating.

But it turns out the project hasn’t been completely abandoned. The AirPower device is still very much in the works, a leaker says, and it’s a critical component when it comes to Apple’s plans of making a next-gen phone.

It may look like we’ve hit the peak of smartphone design, but handset makers aren’t done perfecting the phone yet. The goal is to increase the display so that it occupies the entire front of the device, eliminating buttons and ports. Apple has been working on this vision for years, and we may be closer than expected.

Three things need to happen for the wireless iPhone to become real. First, the notch has to disappear, and all the Face ID sensors need to be placed under the screen. Secondly, wireless AirDrop transfer speeds have to be faster and support larger data files. Finally, the iPhone needs to support fast wireless charging.

The notch is shrinking on this year’s iPhone 12 models, reports say, but it might take a while until the notice disappears. Apple might be making more progress on the other two fronts, though. It’s working on a new Wi-Fi spec called 802.11ay for “ultra-short range” use. And Apple is developing a revamped AirPower model, one that won’t overheat.

Jon Prosser, well-known YouTuber and the source of a myriad of recent leaks, shared more details about Apple’s renewed AirPower plans on Twitter and YouTube:

According to a mid-March tweet, Apple needs AirPower “to push portless iPhone” in the future. That’s why the project has been resurrected, or perhaps never totally died. Prosser followed up on the story a few days ago, posting a new picture of the “C68” prototype that’s currently in the hands of Apple engineers working from home because of the novel coronavirus pandemic:

The leaker then took to YouTube to explain his scoop in great detail.

The original AirPower did not work because of the Apple Watch, Prosser said. The wearable uses a proprietary charging method, and AirPower units would often overheat and catch fire. Apple supposedly had 50,000 AirPower units made at some point, but decided not to launch the product.

The new prototype, seen in the tweet above, as well as in the mockup image that follows (also from Prosser), features the iPhone X’s A11 chip. That’s an upgrade from the A10 processor used in the previous version, but it’s not for added processing power: The A11 is the first A-series chip to intelligently manage heat dissipation.

The chip will supposedly route power to specific coils of the accessory, and cut it when some areas overheat. If the region where the Apple Watch is placed on overheats, the chip would just cut the power and wait for the temperature to drop. The other devices would continue charging.

It’s unclear what sort of charging speeds the AirPower will support. A portless iPhone would have to offer fast wireless charging support and work on any Qi charger, not just AirPower. The Huawei P40 Pro supports 40W wireless charging, and the OnePlus 8 Pro is rumored to get 30W wireless charging as well. The Galaxy S20 supports 15W wireless charging, while the iPhone 11 goes up to 7.5W. It’s unclear what sort of speeds the iPhone 12 will have to offer.

Prosser said on a podcast that the device might cost $250 when it launches in Q4 2020 or Q1 2021. That’s if Apple launches it, of course. That might sound like a lot for a wireless charger, but the AirPower would still be a unique accessory, one that Apple fans who own several devices might appreciate.

A leak from Ming Chi-Kuo said Apple would drop the Lightning connector from the iPhone that will succeed this year’s iPhone 12 series. The only way to make that happen is to either go all in on wireless charging or replace the Lightning port with USB-C.

Prosser’s leaks have been met with resistance, and he might still be wrong about AirPower. But the YouTuber was the first to give us the correct prices for the Galaxy S20 line, and many of his recent coronavirus-related leaks about Apple have come true. The full video about AirPower’s revival follows below.

There’s been a lot of speculation surrounding Apple’s iPhone release schedule as it pertains to both the iPhone 9 and iPhone 12.

Compounding matters, of course, is that the ongoing coronavirus pandemic has completely disrupted Apple’s development process and any initial release timelines it had.

The iPhone 9, for instance, was initially supposed to arrive in stores sometime in March according to a handful of credible sources. The March release date made sense given that the original iPhone SE — which is essentially the predecessor to the iPhone 9 — was released in March of 2016.

A new research note from GF Securities analyst Jeff Pu (via MacRumors) now claims that the compact device — which will boast a 4.7-inch LCD display with Touch ID — will be released in mid-April. We’ve seen a few previous reports claiming that the iPhone 9 would arrive last week, so you’d be well-advised to take Pu’s report with a grain of salt. That said, there’s no denying that the evidence pointing to an iPhone 9 release in April is mounting and increasingly hard to ignore.

In regards to the iPhone 12, Pu anticipates that various issues resulting from the coronavirus pandemic have impacted the device’s developmental timeline by about two weeks. The report notes:

As a result, Pu currently expects the 5.4-inch and two 6.1-inch models to be available in September, followed by the 6.7-inch model in October. This two-phase rollout would be similar to 2018, when the iPhone XS and iPhone XS Max were released in September, followed by the iPhone XR in October.

It’s worth noting that nothing is set in stone at this point given that the situation surrounding the coronavirus remains fluid and is changing from week to week. To this end, we’ve seen reports indicating that Apple won’t make a firm decision regarding the iPhone 12’s release schedule until sometime next month.

As we’ve highlighted before, the iPhone 12 release doesn’t just hinge on getting the engineering finished and starting mass production. There’s also an economic factor to consider. Remember, with millions of people across the world on lockdown, and with unemployment in the United States reaching new heights, the demand for luxury devices like a new iPhone may be significantly lower for months to come. As others have noted, the iPhone 12 will be the first iPhone to support 5G and Apple would ideally like to release it with a lot of fanfare as opposed to releasing it in an economic environment when people

When Microsoft demoed Windows 10X (pronounced like the letter X, not the Roman numeral 10) last year, the company declared that this version of Windows was specifically intended for dual-screen devices like the upcoming Surface Pro Neo (now delayed until after 2020, as covered by my colleague Ryan Whitwam). Now that’s changing, with Windows 10X reportedly being retooled for single-screen devices as well.

Windows 10X is a bit like Windows 10 S, in that it offers a different set of capabilities and functions than the standard Windows 10 model, but that’s where the similarities stop. Windows 10X, for example, will support running at least some Win32 applications in containers. Windows 10X features a reinvented shell, with a brand-new taskbar and Start Menu experience.

The image below, from Windows Central, shows the Start Menu with the taskbar below it. Instead of grouping items from the left-hand side of the screen, the Start button, pinned tasks, and running tasks are centered on the display when running in touch mode. Switch to a mouse, and the system will group the icons in the more traditional left-hand-side fashion.

The new OS variant is said to also feature an all-new setup experience, a new action center, and a capability known as “Compose Mode” which switches the laptop from consumption-based to productivity-based. Compose Mode starts automatically when a keyboard is connected to the device, and it allows for more laptop-centric features like multi-windowed apps.

It’s not entirely clear if Microsoft is making this pivot because of issues directly related to Covid-19. It may be that the company has been unable to finish features on its expected timelines in order to ship Windows 10X on schedule and that the switch to single-screen devices will simplify the OS development process. According to Mary Jo Foley at ZDNet, the containerized Win32 support that Microsoft demonstrated in February of this year simply wasn’t all that good, as far as compatibility is concerned. Also, applications that affect system files, partition hard drives, or require access to functions outside their own sandbox won’t function.

According to Foley, “Officials didn’t discuss how well/badly Win32 apps worked when virtualized on 10X, but the inside word was that the team had a long way to go to make this something ‘normal’ users would understand and accept, as compatibility levels were not great.” The impact on battery life isn’t expected to be heavy, because the Win32 container system is only loaded if it’s actually needed — but that, in turn, implies that users may only see maximum advantage from devices if they don’t plan to run a lot of Win32 apps.

If you’re thinking all of this adds up to “What, exactly is Windows 10X for?” well, you’re on the same page as the rest of us. As a dual-screen OS also intended for foldable devices, Windows 10X seemed to have a distinct purpose. Retooling it as a single-screen OS makes sense if Microsoft wants to position it against Chromebooks, I guess? That’s not the worst idea, but again, the question of whether Windows has a software ecosystem to make the OS attractive seems like it could be a problem.

Microsoft hasn’t had much luck pushing Windows into form factors where it wasn’t previously established, and the delays and pivots aren’t expected to impact the Android-based Surface Duo, shipping later this year. Intel’s Lakefield chips have certain capabilities that only Windows 10X is optimized to use, for example.

The Covid-19 outbreak has screwed up everyone’s launch timelines and product roadmaps, so it’s a pretty good idea to take all these reports with a grain of salt right now. Companies are still discovering which products they’ll need to push back, and some of those decisions may depend on questions like “How effectively can team members still collaborate while working from home?” With everyone still adjusting to our collective new reality, the answers to these questions may not even be known yet.

From the tenor of reporting at ZDNet, it seems as if Microsoft may have committed to an aggressive launch timeframe for the software, only to come up short due to unforeseen circumstances.

Microsoft never sleeps. Even before the Windows 10 November 2019 Update (version 1909) started to roll out, the company began working on upcoming feature updates to Windows 10.

As it did with version 1909, Microsoft has been releasing a series of public preview builds to members of Microsoft’s Windows Insider Program.

After years of using “Redstone” in its code names for upcoming releases, Microsoft switched to a new format with version 1903, released in May 2019. The code names now use a YYH1/YYH2 format, with the YY standing for the last two numbers of the year and H1 or H2 referring to the first or second half of the year. So Windows 10 version 1909, which was released in November 2019, was code-named “19H2” (for second half of 2019). The next feature update, due in the spring of 2020, is code-named 20H1.

In December 2019, Microsoft also changed how its Insider rings work: Now the Fast ring is where new features are introduced for testing, regardless of which Windows 10 release they’ll eventually end up in. The Slow ring is where you’ll get more polished features that will be deployed in the next Windows 10 feature update; at the moment that’s Windows 10 20H1. And the Release Preview ring usually doesn’t see action until shortly before a new feature update is rolled out; it’s meant for final testing of an upcoming release.

Below you’ll find information about preview builds that have been released to the Fast ring, followed by preview builds specifically for 20H1. For each build, we’ve included the date of its release, which Insider ring it was released to, a summary of what’s in the build, and a link to Microsoft’s announcement about it. After that you’ll find summaries of all the preview builds that led up to prior feature updates, from the November 2019 Update (version 1909, code-named 19H2) on back to the Windows 10 Creators Update (version 1703, code-named Redstone 2).

Note: If you’re looking for information about updates being rolled out to all Windows 10 users, not previews for Windows Insiders, see “Windows 10: A guide to the updates.”

Those who received Build 18362.10015 with 19H2 features turned on by default will also receive Build 18362.10019 with all 19H2 features turned on. And those on the Windows 10 May 2019 Update just joining their PCs into the Slow ring to take 19H2 updates will also receive Build 18362.10019 with all 19H2 features turned on.

Windows 10 Insider Preview Build 18363.327 for 19H2

Release date: August 26, 2019

Released to: Release Preview ring

This build is available only for about 10% of the Windows Insiders in the Release Preview ring, and is being used only to test out Microsoft’s throttled approach for rolling out 19H2 once it’s ready. Insiders in the Release Preview ring can go to Settings > Update & Security > Windows Update to see if there is a Windows 10, version 1909 update available. They can then choose to install it or ignore it. If they install it, they will be on 19H2 Build 18363.327.

19H2 Build 18363.327 contains no new features, and in fact has fewer features than the current latest version of 19H2 in the Slow ring.

Windows 10 Insider Preview Builds 18362.10014 & 18362.10015 for 19H2

Release date: August 19, 2019

Released to: Slow ring

These two builds are nearly identical, except that 18362.10014 has new features turned off and 18362.10015 has them turned on. Microsoft did that because it’s testing its ability to turn on features via a controlled feature rollout. So over time, users who download 18362.10014 will eventually see the new features. Whether you’ll download 18362.10014 or 18362.10015 depends on your current build. Those on 19H2 Build 18362.10012 will receive 18362.10014 (which has the features turned off) and those on 19H2 Build 18362.100013 will get 18362.10015, which has them turned on.

There are only a few very minor changes in these builds. The search box in File Explorer is now powered by Windows Search. Enterprises can supplement the Windows 10 in S Mode policy to allow traditional Win32 (desktop) apps from Microsoft Intune. Windows Defender Credential Guard for ARM64 devices now has additional protection against credential theft for enterprises deploying ARM64 devices in their organizations.

Windows 10 Insider Preview Builds 18362.10012 and 18362.10013 for 19H2

Release date: August 8, 2019

Released to: Slow ring

These two builds are nearly identical, except that 18362.10012 has new features turned off and 18362.10013 has them turned on. Microsoft did that because it’s testing its ability to turn on features via a controlled feature rollout. So over time, users who download 18362.10012 will eventually see the new features. Whether you’ll download 18362.10012 or 18362.10013 depends on your current build. Those on 19H2 Build 18362.10005 will receive 18362.10012 (which has the features turned off) and those on 19H2 Build 18362.10006 will get 18362.10013, which has them turned on.

The primary new feature is the ability to create an event straight from the Calendar flyout on the taskbar.  There are other minor changes as well, including that the navigation pane on the Start menu now expands when you hover over it with your mouse, so you can better see where clicking goes. In addition, general battery life and power efficiency improvements have been made for PCs with certain processors.

Windows 10 Insider Preview Build 18362.10005 for 19H2

Release date: July 15, 2019

Released to: Slow ring

This build includes all the fixes released in KB4507453 for the Windows 10 May 2019 Update (version 1903) as well as a handful of very minor changes, including a new feature called Key-rolling or Key-rotation for MDM-managed AAD devices that will help prevent accidental recovery password disclosures as part of manual BitLocker drive unlocks done by users. There is also a change that will let third-party digital assistants voice-activate above the lock screen.

Note that the changes in this build are turned off by default, so users will not see them immediately. Microsoft will turn them on in controlled rollouts at some point.

Windows 10 Insider Preview Build 18362.10000 for 19H2

Release date: July 1, 2019

Released to: Slow ring

This first build for the 19H2 version of Windows 10, the update due sometime this fall, is being released only to the Insider Slow ring. (Those in the Fast ring will continue to get builds for 20H1, due the first half of 2020.)

Insiders will see no changes in this build. Instead, the update contains what Microsoft calls “two behind-the-scenes changes designed for OEMs.” It is being used, according to Microsoft, “to test our process and servicing pipeline for delivering these updates to customers.”

Although Insiders won’t see changes, there is significant news in the Microsoft announcement. Reading between the lines of the Microsoft description of the build and a blog post about 19H2 in general, it appears that the upcoming fall update will contain very few new features, and will be more like what Microsoft used to call a Service Pack — a rollup of multiple changes, delivered in a single build rather than in multiple ones.

In addition, the update won’t be delivered as the company’s twice-annual feature updates have been up until now. Instead, it will be delivered in the same way as a Windows 10 monthly update.
