All the features and changes found in Windows 10 build 21364 (and earlier)
Windows 10 devices enrolled in the Windows Insider Program’s Dev Channel recently picked up Windows 10 build 21364, a new preview that includes a couple of significant changes and several improvements.
For example, in this release, Microsoft is shipping a new update version of the Windows Subsystem for Linux that brings support for Linux GUI apps to Windows 10. Task Manager gets a new Eco mode to limit app access to resources to improve performance, and now the tool displays classifications for Microsoft Edge processes.
Besides build 21364, the company also made available three other previews since our last roundup of changes, including build 21343, 21354, and 21359 that also delivered several changes and visual improvements to the Settings app, File Explorer, Start menu, and more.
In this Windows 10 guide, we will highlight the new features and changes Microsoft has been working on in the Dev Channel of the Windows Insider Program.
Windows 10 Dev Channel changes up to build 21364
These are the most important features and improvements that Microsoft has been working on in the last four preview builds of Windows 10:
Start menu
Although the Start menu remains identical to previous releases, Microsoft has added several changes in the last four builds. For example, starting with build 21343, the “Windows Administrative Tools” folder in the Start menu has now been renamed “Windows Tools.” Also, the entry is no longer a folder either. Instead, it is an option with a new modern icon that opens the Windows Tools page in Control Panel.

Finally, with the rollout of Windows 10 build 21364, Microsoft has removed the “3D Viewer” and “Print 3D” app shortcuts from the menu.
Task Manager
As part of the Dev Channel development, the Task Manager introduces two worthy changes, including process classifications for Microsoft Edge and Eco mode.
Microsoft Edge processes
The process classification means that Task Manager now will be available to display and describe each process for the Chromium version of Edge. The classification breaks down into several categories, including Tabs, Utility plugins (Utility: Audio Service Extensions), Browser processes (Browser, GPU Process, Crashpad), Dedicated & Service workers, and others.

While you won’t be drilling down into these processes often, it will become useful to help determine the resources or websites that are slowing down the system to deal with them accordingly to improve performance.
Eco mode
Eco mode is an experimental feature that gives you the ability to limit system resources to processes manually. Although Windows 10 does a good job managing resources, this new feature will help to deal with apps that may be using a lot of resources, and you would like to restrict its consumption to safe resources for other apps.
The process to enable or disable “Eco mode” is straightforward. You only need to right-click a process, select the “Eco mode” option, and then click the Turn on Eco mode button. If the option is grayed out, you are trying to enable the feature in the process group. In this case, you will need to expand the group and turn on the mode for each child process.

These improvements with Task Manager are available with the rollout of build 21364.
Notifications
In the notifications department, build 21364 updates the notification: “We need to fix your account” to make it clearer. As a result, the notification now reads: “Select here to sign in to your account to continue using apps between this device and your other devices.”
Night light
Windows 10 build 21364 also brings changes to the night light feature. In this flight, when enabling or disabling night light manually through the Settings app or Action Center, the feature will change the state immediately without going through the slow transition.
News and interests
As part of the “news and interests” experience, build 21354 introduced more ways to customize the experience with a new “Manage interest” button that appears in the top-right that takes you to your Microsoft account to adjust the preferences.

File Explorer
Starting with build 21343, Windows 10 ships with an updated version of File Explorer that introduces a new set of modern icons with new styles, colors, and orientations to align with the design changes that Microsoft has been pushing throughout the experience.
The new icons are available across the experience, but you immediately notice the icon designs for the profiles folders, including Desktop, Documents, Downloads, Music, and Pictures.

Even many of the icons inside of the Control Panel have been updated.
Settings app
In the last several builds, Microsoft has also been working to improve the Settings app with many changes and new features.
Display
On Settings > System, the Display page includes an option to disable (or enable) content adaptive brightness control (CABC).
Content adaptive brightness control is a feature on Windows 10 that automatically controls the brightness and contrasts of the display based on the displayed content to improve energy efficiency.
The only downside is that it can cause distracting changes on the screen and reduces image quality. As a result of this problem, Microsoft decided to add the “Automatically adjust contrast based on the display content to help improve battery” option to disable the feature when you need to show content with more accurate colors.

Storage Sense
On Settings > System > Storage, the Storage Sense settings have been updated. For example, the page is now called “Configure Storage Sense,” the settings have been reorganized, and the descriptions have been reworded to make them simpler to understand.
The option to delete temporary files has been moved to the top, and it has been renamed to “Cleanup of temporary files.”

Under the “Configure cleanup schedules” section, you will now find the settings to schedule a Storage Sense cleanup.
Finally, the button at the bottom of the page to manually run the optimization has been renamed “Run Storage Sense now.”
Multitasking
On Settings > System, the Multitasking page, there’s a new “Title bar window shake” option to enable or disable Aero Shake on Windows 10.

Cameras
On Settings > Devices, the Cameras page is new to Windows 10, and it includes the settings to enable or disable cameras, and you can also install and set up network cameras.

Device Usage
On Settings > Personalization, the Device Usage page is new starting with build 21354, and it houses the settings that allow you to configure Windows 10 for how you plan to use the device.

If these settings look familiar is because the feature is already available in the out-of-box experience (OOBE) when performing a clean install on Windows 10.
Accessibility
On Settings, the “Ease of Access” section has been renamed to Accessibility, but the settings haven’t received any new updates in recent builds.

Activity history
On Settings > Privacy, the Activity history page removes the “Send my activity history to Microsoft” option. As a result, Windows 10 now loses the ability to sync activities to the cloud and across devices as part of the Timeline experience.

App permissions
On Settings > Privacy, the Downloads folder, Music library, Screenshot borders, and Screenshots and apps are new pages that allow you to decide which apps can access your downloads folder, music files, and whether to take capture borders in screenshots.

Windows Update
On Settings > Update & Security, the Windows Updates settings since build 21354, Windows 10 turns on the “Automatically adjust active hours for this device based on activity” option automatically inside the “Change active hours” page for devices that never change this setting before. Otherwise, the setting will remain unchanged.

Apps
As part of the app improvements and changes, Windows 10 build 21354 ships with a new version of the Microsoft Paint app that now includes a modern icon and updates from the Microsoft Store. This means that the app will receive updates without having to wait for new releases of Windows.

Windows Subsystem for Linux
The Windows Subsystem for Linux (WSL) has been getting some interesting improvements in the last several builds. For example, on build 21354, a change has been made to the WSL integration in File Explorer that changes the default \\wsl\\
path to \\wsl.localhost\\
, which according to the company, improves performance and reliability.
If you want to use the previous path, you still can, but the experience will be better using the new path.
Starting with Windows 10 build 21364, Microsoft is also shipping a new update for WSL that supports running Linux GUI (graphical user interface) applications to use your mouse and keyboard instead of commands.
The integration works thanks to a new companion system distro that includes an X server, Wayland, pulse audio server, and everything required to render applications using the Linux visual style elements, including for frame, menus, buttons, and options.

This new app integration with the Windows Subsystem for Linux also includes support for speakers, microphones, and GPU acceleration for 3D graphics.
Containers
Beginning with build 21343, the Windows Sandbox and Microsoft Defender Application Guard feature now use a new container technology that makes the experience lightweight and faster to start up.
In addition, the Windows Sandbox container has been updated to include the Chromium version of Microsoft Edge.
Language
On the language side of things, Windows 10 build 21364 introduced a new touch keyboard layout for the Japanese language known as “50-on touch keyboard.”
The layout has been designed to allow users to input text more easily without knowing how to compose Hiragana characters.
While in the touch keyboard, you can enable the new layout by clicking the Settings button, selecting the Keyboard layout menu, and choosing the 50-on option.

Microsoft Edge
While Microsoft Edge gets updates independently from Windows updates, some features still require system updates. For example, in build 21354, Windows 10 includes a change to allow pinned sites to show all the open tabs across windows in the taskbar.
Other changes
In addition to all the new features and changes, Windows 10 also ships with a few other improvements. For instance, starting with build 21364, you will now find support for x64 out-of-process shell extensions. And, you can now enable compatibility settings for x64 applications on devices based on ARM processors.
Also, when there is a problem with the account information on the Shared Experiences page, the system will generate a notification inside Action Center instead of showing multiple toast notifications.

Don’t get distracted by the iMac’s looks — the real story is the price
Apple announced its refreshed iMac 24 this week, and while everyone is focusing on the awkward chin and odd color palette, it’s the price that I find the most interesting. There aren’t many all-in-one Windows PCs out there, and they certainly don’t compete at that price point, processor, and 4.5K display. That’s the real story.
