Canary channel Windows 11 build 26040.1000 Features, Changes, improvements, and bug Fixes

Experience crystal clear online communication with Voice Clarity

The canary channel update under rs_prerelease branch Windows 11 Build 26040.1000 is going to expand Voice Clarity which has been available on Surface devices and making it available to more users. This audio experience enhancement is based on state-of-the-art AI technology. The feature cancels echo, suppresses background noise, and lowers reverberation in real time with the help of low-complexity AI models. This feature is enabled by default and can be utilized by applications using Communications Signal Processing Mode, such as Phone Link and WhatsApp. Since Voice Clarity is compatible with x64 and Arm64 CPUs you don’t have to bother about extra hardware. Apps that use This will work using Communications Signal Processing Mode automatically even on devices that don’t have the facility of Communications Mode processing.

Likewise, Voice Clarity will enhance the experience of PC gamers who use Communications Signal Processing Mode for their online communications. To implement these modifications, apps can give a “toggle switch” for the Deep Noise Suppression stream effect to switch between AI models for voice-only communications (Deep Noise Suppression enabled, the default setting) and generic audio content (Deep Noise Suppression disabled). Voice Clarity will certainly give a boost of confidence when hearing audio during online meetings.

New automatic account management feature in Windows LAPS

Windows 11 Build 26040.1000 rs_prerelease has worked on Windows Local Administrator Password Solution (LAPS) and added a new automatic account management feature. This feature allows IT admins to configure Windows LAPS to automatically create the managed local account. Moreover, the ability to configure the name of the account, enable, or disable the account, and optionally randomize the account name for improved security are added. The build has appended improved integration with existing Microsoft local account management policies.

Here is an image of the new Automatic account management setting:

Improved readability password dictionary (and password font) in Windows LAPS

The update has added a new PasswordComplexity setting to Windows LAPS. This feature will help an IT administrator configure Windows LAPS to create less confusing passwords. This setting is likewise the existing complexity setting 4 in that all four character categories are used (upper case letters, lower case letters, numbers, and special characters). Nevertheless, when PasswordComplexity is configured with the new setting of 5, the most confusing characters are omitted to enhance password readability. For instance, the number 1 and the letter I are never utilized in the new setting.

The below changes are induced to the default password dictionary character set, when PasswordComplexity is set to 5:

  1. Don’t use these letters: ‘I’, ‘O’, ‘Q’, ‘l’, ‘o’
  2. Don’t use these numbers: ‘0’, ‘1’
  3. Don’t use these ‘special’ characters: ‘,’, ‘.’, ‘&’, ‘{‘, ‘}’, ‘[‘, ‘]’, ‘(‘, ‘)’, ‘;’
  4. Start using these ‘special’ characters: ‘:’, ‘=’, ‘?’, ‘*’

The Windows LAPS tab in the AD Users and Computers snap-in (through MMC) has also been improved. When the Windows LAPS password is portrayed in the clear, the password now uses a new font for enhancing readability.

Windows LAPS CSP also gives complete support for setting up the new PasswordComplexity setting (5). The Windows LAPS documentation will be updated at a later date with additional information on this new setting.

New passphrase feature in Windows LAPS

LAPS has been enhanced with a new passphrase feature allowing IT admins to set up this to generate passphrases such as EatsVeganYummyTasty. Compare this to a more traditional style password like “q6Rgag667Pu23qA886?n:K” – the passphrase is much easier to read, repeat, and type.

The current PasswordComplexity policy setting can be set to determine 1 of 3 different passphrase word lists. All 3 passphrase word lists are formed as part of Windows, so no extra download is required. Policy setting  named PassphraseLength which is a new one works to determine the number of words in a passphrase.

Structure of a passphrase is uncomplicated: the configured number of words is randomly chosen from the configured word list and added together. The first letter of each word is capitalized for better readability.

Windows 11 build 26040.1000 canary channel

The new PassphraseLength policy setting:

The new passphrase feature is completely supported when backing passwords up to either Microsoft Entra ID or Windows Server AD.

The source of passphrase word lists is Deep Dive: EFF’s New Wordlists for Random Passphrases which is used according to CC-BY-3.0 Attribution license. Download link of the word lists is https://go.microsoft.com/fwlink/?linkid=2255471.

These 3 PasswordComplexity passphrase settings is taken from Electronic Frontier Foundation passphrase word lists.

LAPS is incompatible with either customer-configured word lists or customization of the built-in word lists.

The Windows LAPS CSP provides full support for controlling these settings. The documentation of Windows LAPS CSP will be revised later to reflect the new settings.

New image rollback detection feature in Windows LAPS

Windows 11 Build 26040.1000 has added rollback detection feature to LAPS. As a result, Windows LAPS will detect when an image rollback if occurred. When a live OS image is rolled back (irrespective of of mechanism such as Hyper-V snapshot reversion, or via image re-deployment products) it ends up with a “torn state” situation oftentimes where the password stored in Active Directory no longer matches the password (hash) stored locally on the device. IT admin can not sign into the device using the saved Windows LAPS password when this happens. The issue is not fixed until Windows LAPS alternates the password per the normal password expiration timestamp, which might not occur for days or weeks.

This adds an Active Directory attribute msLAPS-CurrentPasswordVersion to the Windows LAPS schema. This attribute possesses a random GUID which is documented by Windows LAPS every time a new password is persisted in AD, followed by saving a local copy. During every processing cycle, the GUID stored in “msLAPS-CurrentPasswordVersion” will be queried and matched with the locally persisted copy; if they are distinct, the password will be instantly rotated.

To enable this, run the most delinquent version of the Update-LapsADSchema PowerShell cmdlet. LAPS will keep a note of the existence of the new attribute and begin using it.

Windows LAPS will log a typical new reason when a rollback is detected, for instance:

Windows LAPS event log message when OS rollback is detected.

In case of not running the latest version of the “Update-LapsADSchema PowerShell” cmdlet Windows LAPS will log a 10108 warning event in the event log, but will show normal behavior in all other regards.

It is important to know that no policy settings are used to enable or configure this feature. This is always enabled once the new schema attribute has been added.
