Windows 10 May 2019 Update (version 1903 or 19H1) is an update for Windows 10, which was released to the public on 21 May 2019.
This update introduces some enhancements to the user interface, such as a new light mode theme, new expansion to Fluent design, many internal improvements to the shell, and so on.
It is the first version of Windows 10 to use a more descriptive codename (including the year and the order released) instead of the "Redstone" or "Threshold" codename.
New features and changes[edit | edit source]
- This version includes a new light variant of the Hero wallpaper, replacing the previous one.
- A new light theme has been added. When enabled, icons of UWP apps such as the Microsoft Store change their light accent to a darker one.
- Windows Sandbox, which emulates a Windows desktop for testing potentially malicious applications, has been added as an optional feature. It relies on Hyper-V, and thus requires at least the Pro SKU. However, it can be installed unofficially on the Home SKU.
- Cortana has been separated from the Search function. This can be seen on the Taskbar and in the Settings.
- The ability to pause updates for 35 days as maximum, which was previously only available in at least the Pro SKU, has been ported to the Home SKU.
- Automatic Active Hours has been added. It allows Windows to automatically adjust active hours based on system use activity.
- New icons have been added to the User account and Shut down submenus in the Start menu, the Security options page (which can be invoked by pressing Ctrl+Alt+Delete) and the login screen.
- A system tray icon for Windows Update has been added, which can be enabled in the "Advanced Options" page under "Update & Recovery" in Settings:
- When a reboot is required for installed updates, the Windows Update icon with an orange dot will appear on the system tray to alert users of the reboot requirements.
- If the device has not been rebooted for a while or if the Windows version became out of support, the dot turns red.
- The icon that appears in the login screen and system tray when the device is offline has been replaced with a globe-shaped icon.
- The login screen background now has an “acrylic” blur effect to align with the Fluent Design System. However, it still can be disabled over the registry.
- The brightness title in the Action Center was replaced by a slider.
- Many pages in Settings are redesigned and certain pages also received functionality updates.
- A microphone status icon now appears in the system tray when an app is using the microphone.
- On clean installations starting with this update, Windows will now reserve 7 GB of the device's storage to ensure proper installation of updates. Upgrades are unaffected by this change.
- The Game Bar has been decoupled from the Xbox app and turned into an overlay interface.
- The size and color of the mouse cursor can now be changed.
- The modern setup client used for upgrades (
setupprep.exe) gained some visual updates:- Most notably, the former color scheme of purple for the background and white for the text used since Windows 8 has been replaced by a new color scheme, which uses white for the background and blue for the text. When starting installation, the background color has also been changed from purple to blue.
- In addition, the Microsoft logo, as well as links to support and legal notices have been added to the bottom.
- Lastly, the "Get Updates" page has been changed to no longer show two options of whether checking updates and not. Instead, it shows a notice that setup is about to check for updates. The option to disable the update check can still be reached by clicking on the "Change how Windows Setup downloads updates" link and selecting the option there.
Removed features[edit | edit source]
- The sync feature of the messaging app has been removed.
- The "Product alert" button in Paint was removed.
