Windows 10: A guide to the updates

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 feature updates (such as Windows 10 version 22H2) is released, the company quickly gets to work on improving it by fixing bugs, releasing security patches, and occasionally adding new features.

In this story we summarize what you need to know about each update released to the public for the most recent versions of Windows 10 — versions 22H2 and 21H2. (Microsoft releases updates for those two versions together.) For each build, we’ve included the date of its initial release and a link to Microsoft’s announcement about it. The most recent updates appear first.

For details about how to install and manage Windows updates, see “How to handle Windows 10 and 11 updates.” If you’re looking for information about Insider Program previews for upcoming feature releases of Windows 10, see “Windows 10 Insider Previews: A guide to the builds.”

KB5046613 (OS Builds 19044.5131 and 19045.5131)

Release date: November 12, 2024

Windows 10 November 2021 Update (version 21H2)

Release date: November 16, 2021

Version 21H2, called the Windows 10 November 2021 Update, is the second feature update to Windows 10 released in 2021. Here’s a quick summary of what’s new:

Wi-Fi security has been enhanced with WPA3 H2E standards support.

GPU compute support has been added in the Windows Subsystem for Linux (WSL) and Azure IoT Edge for Linux on Windows (EFLOW) deployments for machine learning and other compute-intensive workflows.

There are also a number of features designed for IT and business:

Windows Hello for Business has a new deployment method called cloud trust that simplifies passwordless deployments.

For increased security, there have been changes to the Universal Windows Platform (UWP) VPN APIs, which includes the ability to implement common web-based authentication schemes and to reuse existing protocols.

Apps can now be provisioned from Azure Virtual Desktop. This allows those apps to run just like local apps, including the ability to copy and paste between remote and local apps.

The release closes the gap between Group Policy and mobile device management (MDM) settings. The device configuration settings catalog has been updated to list more than 1,400 settings previously not available for configuration via MDM. The new MDM policies include administrative template (ADMX) policies, such as App Compat, Event Forwarding, Servicing, and Task Scheduler.

An upgrade to Windows 10 Enterprise includes Universal Print, which now supports print jobs of up to 1GB or a series of print jobs from an individual user that add up to 1GB within any 15-minute period.

Universal Print integrates with OneDrive for web and Excel for web. This allows users of any browser or device connected to the internet to print documents hosted in OneDrive for web to a printer in their organization without installing printer drivers on their devices.

Microsoft has also announced that starting with this release, Windows 10 will get feature updates only once a year.

Windows 10 May 2021 Update (version 21H1)

Release date: May 18, 2021

Version 21H1, called the Windows 10 May 2021 Update, is the most recent update to Windows 10. This is a relatively minor update, but it does have a few new features.

Here’s a quick summary of what’s new in 21H1:

Windows Hello multicamera support: If you have an external Windows Hello camera for your PC, you can set the external camera as your default camera. (Windows Hello is used for signing into PCs.) Why should this change matter to you? If you have an external camera, you probably bought it because it’s superior to the built-in, internal one on your computer. So with this change, you’ll be able to use the more accurate camera for logging into your PC.

Improved Windows Defender Application Guard performance: Windows Defender Application Guard lets administrators configure applications to run in an isolated, virtualized container for improved security. With this change, documents will open more quickly. It can currently take up to a minute to open an Office document in it.

Better Windows Management Instrumentation (WMI) Group Policy Service support: Microsoft has made it easier for administrators to change settings to support remote work.

Windows 10 October 2020 Update (version 20H2)

Release date: October 20, 2020

Version 20H2, called the Windows 10 October 2020 Update, is the most recent update to Windows 10. This is a relatively minor update but does have a few new features.

Here’s a quick summary of what’s new in 20H2:

The new Chromium-based version of the Microsoft Edge browser is now built directly into Windows 10.

The System page of Control Panel has been removed. Those settings have been moved to the Settings app.

The Start menu’s tiled background will match your choice of Windows themes. So the tiled background will be light if you’re using the Windows 10 light theme and dark if you’re using the Windows 10 dark theme.

When you use Alt-Tab, Edge will now display each tab in your browser in a different Alt-Tab window. Previously, when you used Alt-Tab, Edge would get only a single window. You can change this new behavior by going to Settings > System > Multitasking.

When you pin a site to the taskbar in Edge, you can click or mouse over its icon to see all your browser tabs that are open for that website.

When you detach a keyboard on a 2-in-1 device, the device will automatically switch to the tablet-based interface. Previously, you were asked whether you wanted to switch. You can change that setting by going to Settings > System > Tablet.

The Your Phone app gets a variety of new features for some Samsung devices. When using one of the devices, you can interact with the Android apps on your phone from the Your Phone app on Windows 10.

What IT needs to know: Windows 10 version 20H2 also has a variety of small changes of note for sysadmins and those in IT.

IT professionals who administer multiple mobile devices get a new Modern Device Management (MDM) “Local Users and Groups” settings policy that mirrors options available for devices that are managed through Group Policy.

Windows Autopilot, used to set up and configure devices in enterprises, has gained a variety of small enhancement, including better deployment of HoloLens devices, the addition of co-management policies, enhancements to Autopilot deployment reporting, and the ability to reuse Configuration Manager task sequences to configure devices.

Microsoft Defender Application Guard now supports Office. This allows untrusted Office documents from outside an enterprise to launch in an isolated container to stop potentially malicious content from compromising computers or exploiting personal information found on them.

Latest Cumulative Updates (LCUs) and Servicing Stack Updates (SSUs) have been combined into a single cumulative monthly update, available via Microsoft Catalog or Windows Server Update Services.

Biometric sign-on has been made more secure. Windows Hello now has support for virtualization-based security for certain fingerprint and face sensors, which protects, isolates, and secures a user’s biometric authentication data.

For more details, see Microsoft’s “What’s new for IT pros in Windows 10, version 20H2.”

Windows 10 May 2020 Update (version 2004)

Release date: May 27, 2020

Version 2004, called the Windows 10 May 2020 Update, is the most recent update to Windows 10. This is a relatively minor update but does have a variety of new features for both users and system administrators. For more details, see: “Review: Windows 10 May 2020 Update delivers little tweaks that add up to… well, not a lot.”

Here’s a quick summary of what’s new in 2004:

Cortana now runs as a standalone app in a resizable window. It also loses a variety of capabilities, such as playing music, controlling home devices, and working on the lock screen.

Task Manager now displays new information, including the temperature of your GPU and your disk type.

Settings gets many small tweaks, including adding a header with account information, and a redone network status page that combines information that used to be found on multiple pages, such as your IP address, current connection properties and data usage.

The Windows Subsystem for Linux (WSL) gets more features. It now uses a real Linux kernel, and is faster than previously.

IT can now take advantage of Windows Hello biometrics logins rather than passwords, by setting that up as the default on enterprise devices.

Installing and setting up Windows for others has been made easier thanks to new controls added to Dynamic Update, which can lead to less downtime during installation for users.

A variety of new commands have been given to PowerShell for Delivery Optimization, a Windows networking service that reduces bandwidth consumption by sharing the work of downloading update and upgrade packages among multiple devices in business deployments.

The security of the Chromium version of Edge has been improved, thanks to porting Application Guard to it.

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.”

There are two known issues in this update: one in which some users cannot set Win32 program defaults for certain app and file type combinations using the Open with… command or Settings > Apps > Default apps, and another in which Microsoft Notepad and other Win32 programs cannot be set as default applications.

Windows 10 October 2018 Update (version 1809)

Release date: October 2, 2018; paused October 5; re-released November 13, 2018

Version 1809, called the Windows 10 October 2018 Update, is the feature update that preceded the May 2019 Update. Here’s a quick summary of what’s new for users in it. (For more details, see our full review.)

A new, powered-up Windows Clipboard can hold multiple clips, store clips permanently, let you preview clips and choose which one you’d like to paste into a document, and share clips across Windows 10 devices.

A new screenshot and annotation tool called Snip & Sketch lets you capture and annotate the entire screen, a rectangular portion of the screen or a freehand-drawn portion of it. After you take a screen capture, you can annotate it and then save it to a file, copy it to the Clipboard, open it in another program or share it via email, social media and other methods.

Storage Sense, which helps save storage space, now works with OneDrive Files On-Demand to clean out files you’ve downloaded from OneDrive cloud storage to your PC but that you don’t use any longer. You can choose how long you would like the cloud files to stay on your PC unused before you want them deleted, from never to 60 days.

The Microsoft Edge browser lets you set autoplay permissions for sound and video on websites on a site-by-site basis. It also lets you look up word definitions in its built-in eReader for books and PDFs, and mark up PDFs and books using a highlighter and by adding notes.

The new Your Phone app links Windows 10 devices to iOS and Android phones. It allows you to start web browsing on an iOS or Android device and then continue where you left off on your PC. It also lets you view photos on your Android phone from your Windows 10 PC.

Search Previews have been powered up slightly. You no longer need to click to display the preview panel; it opens automatically. It also now shows files found on your PC.

Smaller changes include a new dark theme for File Explorer; the addition of the SwiftKey swipe keyboard, which lets you enter text by swiping a finger across an onscreen keyboard; updates that are less intrusive; and faster sign-ins on shared PCs.

What IT needs to know: There are few significant changes that affect IT in the Windows 10 October 2018 Update, other than New Microsoft Edge Group Policies that let admins enable and disable full-screen mode, printing, the favorites bar, and browser history saves. IT can also allow or ban Edge extensions (not that there are many available) and configure the Home button and new tab page and startup options.

Windows 10 April 2018 Update (version 1803)

Release date: April 30, 2018

Version 1803, called the Windows 10 April 2018 Update, is the major update to Windows 10 that preceded the October 2018 Update. Here’s a quick summary of what’s new for users in it. (For more details, see our full review.)

The most important new feature is Timeline, which lets you review and resume activities and open files you’ve started on your PC, or any other Windows PCs you have. It also tracks what you’ve done on iOS and Android devices if you install Microsoft’s digital assistant Cortana on them and are logged in. It shows a list of activities day by day for up to 30 days. Each activity shows up as a large tile, with the file name and document title or URL and website name across it, and the name of the application or app that created it across the top. Click any activity to reopen it. (Note that at present, Timeline only tracks activities in certain Microsoft programs such as the Edge browser and Office applications.)

The new Diagnostic Data Viewer is supported, which Microsoft is designed to let you see the “diagnostic data collected from your Windows devices, how it is used, and to provide you with increased control over that data.” However, the information is presented in such a complex, technical way that even programmers will likely have a difficult time understanding it. The viewer isn’t built directly into the Windows 10 April 2018 Update. Instead, you have to download it from the Microsoft Store.

The My People feature now lets you pin up to 10 contacts on the Windows taskbar. Previously, you could only pin up to three.

Microsoft Edge gets several minor tweaks, including a revamped Hub, the ability to mute auto-playing audio in tabs, and a forms-filler for web-based forms.

The Notebook feature of Cortana gets a new, cleaner interface for its Notebook. It now has two tabs, Organizer and Manage Skills. The Organizer makes it easier to create lists and set reminders. The Manage Skills tab lets you add “skills” to Cortana, such as controlling your home and its appliances, connecting Cortana to music services such as Spotify, tracking your fitness and more.

You get more control over app permissions, such as whether they can access your camera, location and contacts.

What IT needs to know: IT staff should be aware of these features that are new in the Windows 10 April 2018 Update:

Windows 10 Professional now gets the Windows Defender Application Guard, which protects Microsoft Edge. There’s also a new feature in the application guard that lets users download files inside Edge instead of directly to the operating system, as a way to increase security.

There are new policies for Group Policy and Mobile Device Management (MDM) that can better control how Delivery Optimization is used for Windows Update and Windows Store app updates. You can also now monitor Delivery Optimization using Windows Analytics.

Windows AutoPilot also gets a tweak that lets IT make sure policies, settings and apps are provisioned on devices before users begin using them.

Windows gets the Linux curl and tar utilities for downloading files and extracting.tar archives built directly into Windows. Windows also now natively supports Unix sockets (AF_UNIX) with a new afunix.sys kernel driver. That will make it easier to port software to Windows from Linux as well as from other Unix-like operating systems.

There are a host of improvements to the Windows Subsystem for Linux, which lets you run a variety of Linux distributions on Windows 10. Linux applications can run in the background, some launch settings for Linux distributions can be customized, and Linux applications have been given access to serial devices. The new Unix sockets report is available for the Windows Subsystem for Linux as well as Windows itself.
