Windows 10 update history
Windows 10, version 2004 and Windows Server, version 2004
Updates for Windows 10, version 2004 and Windows Server, version 2004
Windows 10 is a service, which means it gets better through periodic software updates.
The great news is you usually don’t have to do anything! If you have enabled automatic updates, new updates will automatically download and install whenever they’re available, so you don’t have to think about it.
On the left side of this page, you’ll find a list of all the updates released for this version of Windows. You can also find more information about releases and any known issues. Installing the most recent update ensures that you also get any previous updates you might have missed, including any important security fixes.
For more information about the update and how to get it, see:
Current status of Windows 10, version 2004 and Windows Server, version 2004
For the most up-to-date information about Known Issues for Windows and Windows Server, please go to the Windows release health dashboard.
Known issues
Certain Japanese half-width Katakana and full-width Katakana characters that have a consonant mark aren’t interpreted as the same character. When you use the CompareStringEx() function with the NORM_IGNOREWIDTH flag to compare them, these characters are evaluated as different because of an issue in the sorting rule . This issue affects all the updates starting on June 9, 2020 for Windows 10, version 2004.
Open the Command Prompt window ( cmd.exe) with elevated privileges.
Run “reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\Sorting\Versions /ve /d 0006020F /f”
Restart the computer or processes to see the full effect.
Important If you have not installed KB4586853or later on the computer, setting an invalid value in this registry might prevent the computer from starting up.
This workaround reverts the National Language Support (NLS) sorting rule to version 6.2, which is used in Windows 10, version 1909 and earlier. When sharing data between systems, consider applying the workaround consistently. If you use this workaround, conduct sufficient testing and evaluations to mitigate problems caused by different sorting rule versions on multiple systems.

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. This page will provide you with the build numbers for both 1909 and 1903 versions so that it will be easier for support to assist you if you encounter issues.
For more details about the enablement package and how to get the feature update, see the Windows 10, version 1909 delivery options blog.

What’s new in Windows 10, version 2004 for IT Pros
Applies to
- WindowsВ 10, version 2004
This article lists new and updated features and content that are of interest to IT Pros for Windows 10, version 2004, also known as the Windows 10 May 2020 Update. This update also contains all features and fixes included in previous cumulative updates to Windows 10, version 1909.
To download and install Windows 10, version 2004, use Windows Update (Settings > Update & Security > Windows Update). For more information, see this video.
The month indicator for this release is 04 instead of 03 to avoid confusion with Windows releases in the year 2003.
Security
Windows Hello
Windows Hello is now supported as Fast Identity Online 2 (FIDO2) authenticator across all major browsers including Chrome and Firefox.
You can now enable passwordless sign-in for Microsoft accounts on your Windows 10 device by going to Settings > Accounts > Sign-in options, and selecting On under Make your device passwordless. Enabling passwordless sign in will switch all Microsoft accounts on your Windows 10 device to modern authentication with Windows Hello Face, Fingerprint, or PIN.
Windows Hello PIN sign-in support is added to Safe mode.
Windows Hello for Business now has Hybrid Azure Active Directory support and phone number sign-in (MSA). FIDO2 security key support is expanded to Azure Active Directory hybrid environments, enabling enterprises with hybrid environments to take advantage of passwordless authentication. For more information, see Expanding Azure Active Directory support for FIDO2 preview to hybrid environments.
Windows Defender System Guard
In this release, Windows Defender System Guard enables an even higher level of System Management Mode (SMM) Firmware Protection that goes beyond checking the OS memory and secrets to additional resources like registers and IO.
With this improvement, the OS can detect a higher level of SMM compliance, enabling devices to be even more hardened against SMM exploits and vulnerabilities. This feature is forward-looking and currently requires new hardware available soon.
Windows Defender Application Guard
Windows Defender Application Guard has been available for Chromium-based Edge since early 2020.
Deployment
Windows Setup
Improvements in Windows Setup with this release also include:
- Reduced offline time during feature updates
- Improved controls for reserved storage
- Improved controls and diagnostics
- New recovery options
For more information, see Windows Setup enhancements in the Windows IT Pro Blog.
SetupDiag
In Windows 10, version 2004, SetupDiag is now automatically installed.
SetupDiag is a command-line tool that can help diagnose why a Windows 10 update failed. SetupDiag works by searching Windows Setup log files. When searching log files, SetupDiag uses a set of rules to match known issues.
During the upgrade process, Windows Setup will extract all its sources files to the %SystemDrive%$Windows.
bt\Sources directory. With Windows 10, version 2004 and later, Windows Setup now also installs SetupDiag.exe to this directory. If there is an issue with the upgrade, SetupDiag is automatically run to determine the cause of the failure. If the upgrade process proceeds normally, this directory is moved under %SystemDrive%\Windows.Old for cleanup.
Windows Autopilot
With this release, you can configure Windows Autopilot user-driven Hybrid Azure Active Directory join with VPN support. This support is also backported to Windows 10, version 1909 and 1903.
If you configure the language settings in the Autopilot profile and the device is connected to Ethernet, all scenarios will now skip the language, locale, and keyboard pages. In previous versions, this was only supported with self-deploying profiles.
Microsoft Endpoint Manager
An in-place upgrade wizard is available in Configuration Manager. For more information, see Simplifying Windows 10 deployment with Configuration Manager.
Windows Assessment and Deployment Toolkit (ADK)
Download the Windows ADK and Windows PE add-on for Windows 10, version 2004 here: Download and install the Windows ADK.
Microsoft Deployment Toolkit (MDT)
MDT version 8456 supports Windows 10, version 2004, but there is currently an issue that causes MDT to incorrectly detect that UEFI is present. There is an update available for MDT to address this issue.
For the latest information about MDT, see the MDT release notes.
Servicing
Delivery Optimization
Windows PowerShell cmdlets have been improved:
- Get-DeliveryOptimizationStatus has added the -PeerInfo option for a real-time peak behind the scenes on peer-to-peer activity (for example the peer IP Address, bytes received / sent).
- Get-DeliveryOptimizationLogAnalysis is a new cmdlet that provides a summary of the activity in your DO log (# of downloads, downloads from peers, overall peer efficiency). Use the -ListConnections option to for in-depth look at peer-to-peer connections.
- Enable-DeliveryOptimizationVerboseLogs is a new cmdlet that enables a greater level of logging detail to assist in troubleshooting.
- Enterprise network throttling is enhanced to optimize foreground vs. background throttling.
- Automatic cloud-based congestion detection is available for PCs with cloud service support.
The following Delivery Optimization policies are removed in this release:
- Percentage of Maximum Download Bandwidth (DOPercentageMaxDownloadBandwidth)
- Reason: Replaced with separate policies for foreground and background.
- Max Upload Bandwidth (DOMaxUploadBandwidth)
- Reason: Impacts uploads to internet peers only, which isn’t used in enterprises.
- Absolute max throttle (DOMaxDownloadBandwidth)
- Reason: Separated to foreground and background.
Windows Update for Business
Windows Update for Business enhancements in this release include:
Intune console updates: target version is now available allowing you to specify which version of Windows 10 you want devices to move to. Additionally, this capability enables you to keep devices on their current version until they reach end of service. Check it out in Intune, also available as a Group Policy and Configuration Service Provider (CSP) policy.
Validation improvements: To ensure devices and end users stay productive and protected, Microsoft uses safeguard holds to block devices from updating when there are known issues that would impact that device. Also, to better enable IT administrators to validate on the latest release, we have created a new policy that enables admins to opt devices out of the built-in safeguard holds.
Update less: Last year, we changed update installation policies for Windows 10 to only target devices running a feature update version that is nearing end of service. As a result, many devices are only updating once a year. To enable all devices to make the most of this policy change, and to prevent confusion, we have removed deferrals from the Windows Update settings Advanced Options page starting on Windows 10, version 2004. If you wish to continue leveraging deferrals, you can use local Group Policy (Computer Configuration > Administrative Templates > Windows Components > Windows Update > Windows Update for Business > Select when Preview builds and Feature Updates are received or Select when Quality Updates are received). For more information about this change, see Simplified Windows Update settings for end users.
Networking
Wi-Fi 6 and WPA3
Windows now supports the latest Wi-Fi standards with Wi-Fi 6 and WPA3. Wi-Fi 6 gives you better wireless coverage and performance with added security. WPA3 provides improved Wi-Fi security and secures open networks.
In this release, Tunnel Extensible Authentication Protocol (TEAP) has been added as an authentication method to allow chaining together multiple credentials into a single EAP transaction. TEAP networks can be configured by enterprise policy.
Virtualization
Windows Sandbox
Windows Sandbox is an isolated desktop environment where you can install software without the fear of lasting impact to your device. This feature was released with Windows 10, version 1903. Windows 10, version 2004 includes bug fixes and enables even more control over configuration.
- MappedFolders now supports a destination folder. Previously no destination could be specified, it was always mapped to the Sandbox desktop.
- AudioInput/VideoInput settings now enable you to share their host microphone or webcam with the Sandbox.
- ProtectedClient is a new security setting that runs the connection to the Sandbox with extra security settings enabled. This is disabled by default due to issues with copy & paste.
- PrinterRedirection: You can now enable and disable host printer sharing with the Sandbox.
- ClipboardRedirection: You can now enable and disable host clipboard sharing with the Sandbox.
- MemoryInMB adds the ability to specify the maximum memory usage of the Sandbox.
Windows Media Player is also added back to the Sandbox image in this release.
Windows Sandbox also has improved accessibility in this release, including:
- Microphone support is available.
- Added functionality to configure the audio input device via the Windows Sandbox config file.
- A Shift + Alt + PrintScreen key sequence that activates the ease of access dialog for enabling high contrast mode.
- A ctrl + alt + break key sequence that allows entering/exiting fullscreen mode.
Windows Subsystem for Linux (WSL)
With this release, memory that is no longer in use in a Linux VM will be freed back to Windows. Previously, a WSL VM’s memory could grow, but would not shrink when no longer needed.
WSL2 support has been added for ARM64 devices if your device supports virtualization.
For a full list of updates to WSL, see the WSL release notes.
Windows Virtual Desktop (WVD)
Windows 10 is an integral part of WVD, and several enhancements are available in the Spring 2020 update. Check out Windows Virtual Desktop documentation for the latest and greatest information, as well as the WVD Virtual Event from March.
Microsoft Edge
Read about plans for the new Microsoft Edge and other innovations announced at Build 2020 and What’s new at Microsoft Edge Insider.
Also see information about the exciting new Edge browser here.
Application settings
This release enables explicit Control over restarting apps at sign-in (Build 18965) that were open when you restart your PC.
Windows Shell
Several enhancements to the Windows 10 user interface are implemented in this release:
Cortana
Cortana has been updated and enhanced in Windows 10, version 2004:
Productivity: chat-based UI gives you the ability to interact with Cortana using typed or spoken natural language queries to easily get information across Microsoft 365 and stay on track. Productivity focused capabilities such as finding people profiles, checking schedules, joining meetings, and adding to lists in Microsoft To Do are currently available to English speakers in the US.
- In the coming months, with regular app updates through the Microsoft Store, we’ll enhance this experience to support wake word invocation and enable listening when you say “Cortana,” offer more productivity capabilities such as surfacing relevant emails and documents to help you prepare for meetings, and expand supported capabilities for international users.
Security: tightened access to Cortana so that you must be securely logged in with your work or school account or your Microsoft account before using Cortana. Because of this tightened access, some consumer skills including music, connected home, and third-party skills will no longer be available. Additionally, users get cloud-based assistance services that meet Office 365’s enterprise-level privacy, security, and compliance promises as set out in the Online Services Terms.
Move the Cortana window: drag the Cortana window to a more convenient location on your desktop.
For updated information, see the Microsoft 365 blog.
Windows Search
Windows Search is improved in several ways. For more information, see Supercharging Windows Search.
Virtual Desktops
There is a new Update on Virtual Desktop renaming (Build 18975), where, instead of getting stuck with the system-issued names like Desktop 1, you can now rename your virtual desktops more freely.
Bluetooth pairing
Pairing Bluetooth devices with your computer will occur through notifications, so you won’t need to go to the Settings app to finish pairing. Other improvements include faster pairing and device name display. For more information, see Improving your Bluetooth pairing experience.
Reset this PC
The ‘reset this PC’ recovery function now includes a cloud download option.
Task Manager
The following items are added to Task Manager in this release:
- GPU Temperature is available on the Performance tab for devices with a dedicated GPU card.
- Disk type is now listed for each disk on the Performance tab.
Graphics & display
DirectX
New DirectX 12 features are available in this release.
2-in-1 PCs

The screen will be optimized for touch when you detach your two-in-one’s keyboard, but you’ll still keep the familiar look of your desktop without interruption.
Specialized displays
With this update, devices running Windows 10 Enterprise or Windows 10 Pro for Workstations with multiple displays can be configured to prevent Windows from using a display, making it available for a specialized purpose.
- Fixed-function arcade & gaming such as cockpit, driving, flight, and military simulators
- Medical imaging devices with custom panels, such as grayscale X-ray displays
- Video walls like those displayed in Microsoft Store
- Dedicated video monitoring
- Monitor panel testing and validation
- Independent Hardware Vendor (IHV) driver testing and validation
To prevent Windows from using a display, choose Settings > Display and click Advanced display settings. Select a display to view or change, and then set the Remove display from desktop setting to On. The display will now be available for a specialized use.
Desktop Analytics
Desktop Analytics is a cloud-connected service, integrated with Configuration Manager that provides data-driven insights to the management of Windows endpoints in your organization. Desktop Analytics requires a Windows E3 or E5 license, or a Microsoft 365 E3 or E5 license.
