Windows 10 version 1903, April 2019 Update

Windows 10 version 1903, April 2019 Update: All the new features and changes

UPDATED 2/21: Windows 10 version 1903 (April 2019 Update) is expected to rollout sometime during spring 2019, and here are all the new features and changes that Microsoft has added to the new version thus far.

Windows 10 version 1903, April 2019 Update (19H1), will be the seventh major refresh that Microsoft is planning to release sometime in April (or early May) time frame with new features and improvements. 

Also, it’ll be the first of two updates coming in 2019, and while we’re still weeks away from the final release, thanks to the previews available in the Windows Insider Program, we now have a clear idea of the changes that will be coming with the “April 2019 Update” (assuming the name will follow the scheme as we’ve been seeing in previous releases).

In this guide, we’ll highlight the new features and improvements planned for version 1903 as they appear in each test preview. (You can also check all the new changes available with version 1809 (October 2018 Update) here.)

Info: This guide gets updated and republished with features and improvements as they become available through the Windows Insider Program. However, depending on when you’re reading this guide, some features and changes may still missing. If this is case, you can check this section with the latest updates.

What’s new with desktop experience

You can check out this walkthrough video with all the changes included in the most recent Windows 10 Insider Preview builds.

Starting with version 1903, Windows 10 is adding acrylic effect, part of Fluent Design, to the sign-in background. “The translucent texture of this transient surface helps you focus on the sign-in task by moving the actionable controls up in the visual hierarchy while maintaining their accessibility” — Microsoft explains.

If you don’t like the new experience, you can disable the acrylic effect on the sign-in screen using a policy in this location: Group Policy Editor under Administrative Templates > System > Logon > “Show clear logon background”.

Start menu

In the Start menu, you won’t find big changes, but now you can right-click on a group name or tile folder, and you’ll now have an option to unpin it.

When you hover over the navigation pane in the Start menu, after a short period it will now automatically expand. Also, when you click the power button, you’ll notice new icons for “Sleep,” “Shut down,” and “Restart.”

When you click the profile menu, you’ll also see icons for “Change account settings,” “Lock,” and “Sign-out.”

Also, the Start menu is debuting with a new simplified default layout that will appear on new installations and new accounts. According to the company, the new layout has been simplified into a sleek one column design with reduced top-level tiles.

In addition, the Start menu will now appear on its own separate process called: StartMenuExperienceHost.exe to simplify debugging and insulating Start from potential issues impacting other surfaces.

Search and Cortana

Starting with the Windows 10 April 2019 update, Microsoft is breaking Cortana and Search into two separate experiences in the taskbar. As a result, when you start a search, you’ll notice an updated landing page with better spacing to show recent activities and most recent apps, adding light theme support with some subtle acrylic effect over all the search filter options.

In addition, in the Settings app, you’ll now find two pages, one to control the Cortana settings and another page to configure the search experience.


In the taskbar, more specifically in the notifications area, Windows 10 is also including a new “disconnected” icon when there’s not an internet connection on your device. This icon will appear when no connection to the internet is detected for Ethernet, Wi-Fi, and Cellular adapters.

There’s a new microphone icon in the system tray which appears when your microphone is in use, which if hover over with the mouse will also show which app is currently accessing the device. If you have multiple apps accessing the microphone, then you’ll only see the number of apps using the device. Also, if you now double-click the icon, it’ll open the Microphone settings page.

In addition, you’ll see an updated Windows Update icon in the notification area (and in the Start menu power button) with an orange indicator alerting you that a restart is pending.

As part of a continuous effort to improve File Explorer, you’ll now find a new default date format, which is called friendly dates to show dates in a conversational format. For example, “5 hours ago,” instead of “12/24/2018 1:15 PM.”

The new format simplifies the date modified column and provides consistency with other views that you see throughout the operating system, apps, and on the web.

The “Downloads” folder now shows the most recent downloaded files at the top to help users to find content faster as most people never spacify a new name of internet files, and then they get lost in the folder.

Also, File Explorer now allows you to rename a file using a dot at the beginning of the name (for example, “.gitignore”).


If you’re using the new clipboard experience on Windows 10, beginning with this new version, the interface is getting updates to optimize the design for text snippets making each entry smaller to see more content.

Light theme

Starting with Windows 10 version 1903, there’s a new system light theme that brings lighter colors for the Start menu, Action Center, taskbar, touch keyboard, and other elements that didn’t have a true light color scheme when switching from the dark to light system theme.

The new changes are also available across the operating system, when an username and password is required, such as when creating a new account.

What’s new with Settings experience

In the update planned for April 2019, the Settings app is also getting a number of refinements. For instance, you’ll find a new way to help users finish their Windows setup and quickly access some of the most frequently used settings.

Inspired by the Microsoft account homepage, the Settings home page now has a header allowing you to take quick actions for things like signing in and managing your Microsoft account. It also gives you an “easy to glance” at system status, such as when updates are available.

The Storage settings page has been redesigned to see at glance how space is been utilized, instead of having to select each drive to see the same information, which wasn’t very intuitive for many users.

As a result of this change, you’ll no longer find the Storage sense section, but you can still access the settings to enable, disable, and configure the feature by clicking the Configure Storage Sense or run it now link under “Storage.”

Windows 10 will also recommend troubleshooting for other problems that aren’t critical to normal operation, but might be impacting your experience. For example, the operating system may recommend disabling a setting that sometimes causes an app or feature to crash unexpectedly until an update is available.

Also, you will see notifications when there is a recommended troubleshooter available for your device. If you click the notification, the Settings app will open in the Troubleshoot page, where you can choose whether to run the recommended troubleshooter or ignore it.

If you want to see the problems that Windows 10 fixed on your behalf, you click the View history link.

The UI for Automation framework now includes support for IAccessible2 information from Google Chrome, which supports IAccessible2 rather than UI Automation. This enables UI Automation clients to receive the IAccessible2 information through the UI Automation client interfaces.

Narrator now includes “Read by Sentence,” which allows you to read next, current, and previous sentences with Narrator. The new feature is available with the keyboard and with touch. (Move by sentence doesn’t yet work for Braille.)

  • Caps + Ctrl + Period (.): Reads next sentence.
  • Caps + Ctrl + Comma (,): Reads current sentence.
  • Caps + Ctrl + M: Reads previous sentence.

Sentence is now a new Narrator view and can be reached using the Caps + Page Up or Caps + Page Down keyboard shortcut, and then, you can navigate with Caps + Left arrow for move by previous sentence and Caps + Right arrow for move by next sentence.

Moving forward Narrator will alert you when you’re accidentally typing with Caps Lock turned on. The setting is enabled by default. To adjust this setting, open the Narrator Settings (Ctrl + Win + N), then navigate to the “Change how much content you hear” heading and review the combo box for “Change when you receive Caps Lock warnings while typing”.

You can now use the text reading commands to scan the window. It’s also possible to use “read by sentence” command with a braille display hitting the dots 2-3-4 or 2-3-4-7 in command input mode. The view options are now more consistent, and you’ll hear control information more consistently. 

Character phonetic reading will no longer announce the phonetic information (“a Alpha,” “b Bravo,” c “Charlie”) automatically. If you need the phonetic information to disambiguate characters, you can issue a command to hear the phonetics. Use the keyboard command of Narrator key + Comma twice quickly.

Also, with version 1903, the experience includes a new “Narrator Home,” which will launch every time that you start Narrator with everything you need to start using the experience.

When using a web browser, you can use the Narrator + 0 command to read the complete URL aloud.

It’s now possible to use capitalization for all reading modes. (You can use the Narrator + 4 command to turn it on or off.) 

The text-reading commands are now available to read an entire window, and you can have Narrator read groups of keyboard keys when pressed. You can independently select Hear letters, numbers, and punctuation as you type, Hear function keys as you type, Hear arrow, Tab, and other navigation keys as you type, Hear when toggle keys like Caps lock and Num lock are turned on or off, and Hear Shift, Alt, and other modifier keys as you type.

When viewing a website, the reading and navigation commands now stay in the page on supported web browsers, and when reading emails with Outlook or the Mail apps.

Starting with this new version of Windows 10, Narrator will stop announcing non-selected in a table when the aria-selected isn’t set on Microsoft Edge, when navigating to a nested table, and when you leave and re-enter a table when reading a single table continuously.

In addition, Narrator now recognizes combo edit controls and will speak them as “combo edit” instead of just “edit.” And if you forget your PIN or password, Narrator will stay on the whole time while you reset it.

The Read Current character phonetics adds Narrator + 5 twice command to render current character phonetics.

When Scan Mode is enabled and Narrator is on a slider, the left and right arrows will decrease and increase the slider. Up and down arrows will continue to navigate to the previous or next paragraph or item. Home and End will move the slider to the beginning or the end.

Also, Narrator now announces the state of hardware buttons such as volume keys.


If you write in Vietnamese, Windows 10 now includes Vietnamese Telex and Number-key based (VNI) keyboards for the touch-based keyboard.

As part of the input improvements, you can now access even more symbols and special characters from the touch keyboard. Once in the number and symbols view (&123) on the touch keyboard, just tap the new ‘Ω ‘ key and you’ll now see a number of tabs with lists of symbols.

In addition to the Indic Traditional INSCRIPT keyboards already available, with this new version, Windows 10 is adding Indic Phonetic keyboards for Hindi, Bangla, Tamil, Marathi, Punjabi, Gujarati, Odia, Telugu, Kannada and Malayalam.

“How does a phonetic keyboard work? Basically, it’s a convenient way of typing that leverages the English QWERTY keyboard – as you type, we use transliteration to suggest possible Indic text candidates. For example, if you typed “namaste” using the Hindi Phonetic keyboard we would suggest नमस्ते.” — Microsoft explains.

Windows 10 version 1903 now adds a notification, which will appear the very first time you press Left Alt + Shift to explains that the hotkey triggers an input language change, and includes a direct link to the settings where the hotkey can be disabled, if pressing it was unintentional.

Touch keyboard

If you use the touch keyboard, you’ll now be able to type faster more accurately. Starting with this flight, Windows 10 will detect your typing behavior and dynamically adjust the hit target of each key, based on prediction of what letter most likely will be typed next.

Also, Windows 10 is making some changes to reduce the number of times in tablet mode where the touch keyboard ends up occluding the text field when docked.


The SwitfKey feature that provides more accurate autocorrections and predictions when using the touch keyboard experience is now expanding to more languages, including:

  • English (Canada) – en-CA

  • Spanish (United States) – es-US

If you’re using a hardware keyboard, text suggestions are also supported with the above languages.

In this version, Windows 10 is updating the Japanese IME by redesigning how it works with applications, and the candidate window interface has been updated to be cleaner and more polished.

As part of this work, all your Japanese IME settings have now been fully integrated into Settings. If you would like to see them, the fastest way there is to right-click the IME mode indicator in the taskbar and select Settings.

Emoji panel

Starting with the April 2019 Update, when you press Windows key + (period) or Windows key + (semicolon), in addition to emoji the picker that appears will now include symbols and kaomoji too.

As part of the symbols, you’ll find sections for punctuation, currency, geometric, math, Latin, and language symbols. As you pick them, your most commonly used symbols, the most recently used tab will populate with them, so it will be even easier to select them next time.

Also, this version ships with emoji 12.

What’s new with system experience

As part of the 19H1 development, Microsoft is also introducing a new group policy for prevent the use of security questions for local accounts. This can be found under Computer Configuration > Administrative Templates > Windows Components > Credential User Interface.

Reserved Storage

Starting with Windows 10 version 1903, April 2019 Update, Microsoft is introducing “Reserved Storage,” which is a new feature that sets aside part of your device available storage to reduce problems upgrading to a new version or installing updates as a result of not enough space.

Reserved Storage will set aside around 7GB of storage for updates, temporary files, system cache, and apps. When a new update is available, Windows 10 will delete the files located in the reserved storage automatically to make room to install the update.

Reserved Storage on Windows 10
Reserved Storage on Windows 10

If the space isn’t enough, then system will clean up other unnecessary files to make the space needed. In the case, the available space still not enough, then you’ll be advised to free space manually or connect another external storage, such as USB flash drive, which the system can use as temporary storage.

Over time, depending on how you use the device and based on diagnostic data, the amount of reserved space may increase in the future.

Users won’t be able to delete the reserved storage, but you’ll be able to adjust the amount of storage the system can set aside by removing optional features or languages installed on your device.

The feature will be enabled automatically on devices that come pre-installed with Windows 10 version 1903, or after performing a clean installation of the operating system. If you want to enable Reserved Storage on an existing installation, you can trigger a request using these steps.

Fiber Local Storage (FLS)

Also, in this new version, Windows 10 is increasing per-process Fiber Local Storage slot allocation. This change will positively impact any application that dynamically loads hundreds or thousands of unique DLLs that have statically-linked Visual C++ runtimes, or otherwise allocate FLS slots.

Reset this PC

If you use the Reset this PC feature, after installing version 1903, you’ll find a new experience to reinstall Windows 10 with a new interface that is more consistent across devices with different configurations, and it now requires fewer steps to complete.


In the Registry, when pressing the F4 key, you’ll see a caret at the end of the address bar, expanding the autocomplete drop-down.


In this major update, Windows 10 is also modifying the brightness behavior to prevent the display becoming brighter when moving from a battery charger to battery power.

“If a person adjusts their display brightness, that brightness will now be remembered as their preferred brightness whether they are on battery or connected to a charger.”

Windows Console

Ctrl + Mouse Wheel Scroll to zoom in text is now supported in Command Prompt, PowerShell and Windows Subsystem for Linux (WSL).

In addition, when using dark system theme, the scrollbars for Command Prompt, PowerShell and WSL will now become dark as well.
