What’s new for Windows 10, version 1909 and Windows 10, version 1903 release notes

Windows 10, versions 1903 and 1909 share a common core operating system and an identical set of system files. As a result, the new features in Windows 10, version 1909 were included in the recent monthly quality update for Windows 10, version 1903 (released October 8, 2019), but are currently in a dormant state. These new features will remain dormant until they are turned on using an enablement package, which is a small, quick-to-install “master switch” that simply activates the Windows 10, version 1909 features.

To reflect this change, the release notes for Windows 10, version 1903 and Windows 10, version 1909 will share an update history page. Each release page will contain a list of addressed issues for both 1903 and 1909 versions. Note that the 1909 version will always contain the fixes for 1903; however, 1903 will not contain the fixes for 1909.

What is the latest Windows 10 version that is available for download

It is well known that since the release of Windows 10 Microsoft releases new major updates every six months. In case you are not sure what is the latest Windows 10 latest version available or the version that is installed on your computer, then this guide will help to figure it out and also help you get the latest Windows 10 version.

What is Windows 10 latest version

There are multiple ways to figure out Windows 10 latest version. You can do it from the Microsoft website, or you can do it on your computer.

Microsoft Software Updates

In mid-October, Microsoft announced the availability of Windows 10 version 20H2, known as the October 2020 Update. But 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 each update released to the public for the most recent versions of Windows 10; currently that’s version 20H2 and version 2004 (also known as the May 2020 Update). These two versions are similar enough that Microsoft is releasing their updates 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 are on top.

And 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.”

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.

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.
