Beta Test New Theme Features

07/11/20 Update below. This post was originally published on April 19th, 2018. It has been updated to reflect the latest version of Mach2 and the most current Windows 10 build.

  • The test additionally adds new reaction emojis — the 100, raised hand, fist, peace sign and wave — along with reporting and blocking tools, a “very early version” of automatic transcriptions,.
  • Previously, those features were tested by Google users picked at random to beta test. Currently, the new features available for Premium subscribers to test include watching videos with sound.

Windows 10 builds, especially Insider builds, contain many hidden features used by Microsoft to test or developer new features that are not officially released yet. These hidden features, though, are not enabled by default and require a special method to activate them.

1 Features 1.1 Aggregate Feature 1.2 Ore Feature 1.3 Scatter Feature 1.4 Single Block Feature 2 Feature Rules This is the features documentation for Bedrock Edition beta New features, components, and capabilities in this release are not final and might change without notice before the final release.

Will there be new Calendar and People experiences in the beta? We’ll roll out new experiences to those areas in the coming months. I have issues with the beta. Please see Get help with the beta, and if your issue.

This is where a tool called Mach2 comes into play that was released by Windows expert Rafael Rivera.

When originally released, you had to compile the program and scan debug symbols to find new hidden features in Windows 10 builds.

You can now simply download the program and consult Rivera's GitHub repository for the latest features found in a newly released Windows 10 Insider build.

According to Rafael, these hidden features are located in Feature Control, which 'is a system used to gate off new and unfinished features from production users in production code.'

Using Mach2, you can manage the Feature Store, a component of Feature Control, to find, disable, and enable features that are normally hidden from non-Microsoft users.

Below we will explain how you can download Mach2 and use it to enable hidden features in Windows 10 builds.

How to use Mach2 to find hidden features in Windows 10

Before we start, it should be noted that Rafael warned that enabling hidden development features could cause problems with your Windows 10 installation. Therefore, they should only be used on a system that you do not care what happens, such as a virtual machine with a saved snapshot.

To get started, download Mach2 from the program's release page. Once downloaded, extract the zip file and open a Windows 10 elevated command prompt.

At the command prompt, 'cd' into the folder where you extracted Mach2 and type 'mach2.exe -help' to see the program's instructions.

To see what features are currently enabled in Windows 10, enter the 'mach2 display' command. If you have not previously enabled or disabled any features, the listings will be empty.

If you have enabled/disabled features already, then those listed features will be displayed. As you can see below, the feature corresponding to ID 23615618 is enabled.

The feature ID '23615618' corresponds to the new theme-aware Start Menu that is being developed.

After a new Windows 10 Insider build is released, Rivera will create a text file that compares the available features in the newly released build with the previous one. He then hosts these files on his GitHub page so that you can see the new features that were added in this release.

These features commonly use internal Microsoft names that do not make it clear what they do, and you will need to experiment with them to learn more.

For example, in the latest Windows 10 Insider build 20161, Rivera lists various new features (in green) found in this build that you can test. One of these features is called 'LivePreviewForTabs' and has an ID of '25478404'.

This feature is a test of a new ALT+Tab change that shows Microsoft Edge tabs in the Windows task list.

To enable this feature, you would type 'mach2 enable 25175482' and press enter.

To disable a feature, we would use the 'mach2 disable 25175482' command.

When disabling or enabling features, you may need to reboot the computer to be fully enabled or disabled.

Now that you know how to find, display, enable and disable hidden features, it's time to start playing around and seeing what you can find.

Below I have listed some of the features that I could activate in Windows 10 Insider build 20161 using Mach2.

Hidden Features in Windows 10 Insider Build 20161 (21H1?)

I briefly went through the list of features in build 20161 and found a few that can be enabled. It should be noted that hidden features can sometimes be fickle and not work all of the time.

The hidden features we found are listed below.


System Control Panel Redirect (RedirectSystemControlPanel - ID: 25175482)

Microsoft has started testing the removal of the System control panel on Windows 10 and instead redirecting users to a new modern About page.

Theme-aware Start Menu (ThemeAwareAndFluentTiles - ID: 23615618)

New Windows 10 Start Menu tiles with colored backgrounds and hello to partially transparent theme-aware tiles that look so much nicer.

Last March, ProtonMail launched out of beta. This March, we’re bringing back ProtonMail Beta so you can test new ProtonMail features before they are released.

Today, we’re announcing the immediate availability of a new site, where we will be hosting experimental releases of ProtonMail. As many of you probably recall, ProtonMail spent over two years in beta before it was finally released to the world in March 2016. During our original beta, we worked closely with our user community to refine and develop ProtonMail into the world’s best secure email service.

As a community driven project, ProtonMail’s development path has always been driven by the user community, and the beta site will serve as a way for interested members of the ProtonMail community to provide feedback on new features prior to public release. Anybody can access the ProtonMail beta site, and will qualify for our security bug bounty program.

Note, there is also an existing ProtonMail Mobile Beta Program, which will continue to be actively maintained and supported by the ProtonMail Team.

Release Notes and Feedback

At the bottom of this post, we will be publishing up to date release notes for the ProtonMail beta releases. The ProtonMail version can always be found in the bottom left corner of the web app. Feedback on beta features and beta versions can be provided in the comments below, or they can be discussed on social media:


As before, requests for new features can be proposed and voted on, in the ProtonMail feedback forum:

Reporting Bugs

Note, will be hosting experimental builds, which are more likely to have bugs, as beta builds generally undergo less strenuous testing. If you find a bug in ProtonMail Beta, please let us know using the report bug feature built into ProtonMail:

Theme Developers

For the ProtonMail custom theme developer community, will serve as a tool to test your theme on new ProtonMail builds before they go public, so your custom theme can be tweaked to account for any new features or CSS changes.
