Hello Windows Insiders, today we are releasing Windows 10 Insider Preview Build 21387 to Windows Insiders in the Dev Channel.
Changes and Improvements
- The Internet Explorer 11 desktop application is now retired as of this Insider Preview build. For additional details see https://aka.ms/IEmodeblog.
- We are turning off the “Eco mode” feature in Task Manager in order to refine the experience and address several issues thanks to Windows Insider feedback.
Fixes
- We fixed an issue in the previous flight where during the upgrade and in the welcome screens displayed after first sign in, the text was unexpectedly using the Times New Roman font.
- We fixed an issue resulting in some Insiders seeing errors when trying to launch Notepad via the Run dialog.
- We fixed an issue for WSL users, preventing some Linux GUI apps from launching correctly via the shortcut that is automatically added to Start menu.
- We fixed an issue resulting in the reset or change PIN workflows not working.
- We fixed an issue where for some Insiders, night light was immediately turning off after being enabled.
- We fixed an issue in recent flights where you might unexpectedly get a “We can’t find an audio device” error when trying to play audio from a connected Bluetooth speaker.
- We fixed an issue where explorer.exe might crash after repeated use of the touchpad gesture for switching Virtual Desktops.
- We fixed two issues impacting the ability to print using USB printers.
- We fixed an issue resulting in the Windows Update page potentially becoming unresponsive after clicking Pause Updates.
- We fixed an issue causing some devices to fail with error code 0xc1900101. While this fix will resolve the problem on some devices, there is a second issue causing the same error code (noted below). We’re working on a fix for this issue as well.
- We fixed an issue where some devices were re-offered the .NET update after it is installed. After taking this build you should no longer be reoffered the .NET update. If you experience and issue getting Build 21387 because of a pending .NET update, you can work around the issue by pausing then un-pausing updates.
- We fixed an issue where some devices would crash with a DPC_WATCHDOG_VIOLATION error when using OneDrive Personal Vault.
- We fixed a ctfmon.exe crash when using ATOK (a third-party IME) if reconversion was triggered in some win32 apps.
Known issues
- The Windows Camera App currently does not respect the default brightness setting set via the new Camera Settings page.
- We’re investigating an issue where elements of Search (including the search box in File Explorer) are no longer displaying correctly in dark theme.
- [News and interests] We’re investigating an issue where the flyout may occasionally flash in the top left corner of your screen after clicking the button on your taskbar.
- We’re working on a fix for a second issue causing some devices to fail when updating to this build with error code 0xc1900101. When the update fails, it will roll back to the previous build. If you are encountering this issue, we recommend pausing updates until we release a build with the fix.

Добрый вечер, друзья! Компания Microsoft выпустила новую предварительную сборку Windows 10 под номером 21387 для участников программы Windows Insider, использующих канал Dev.
Полный номер сборки: 21387.1.co_release.210518-1436.
Недавно имя ветки изменилось на CO_RELEASE. Как и в октябре, когда инсайдеры начали получать сборки из ветки FE_RELEASE, компания практикует возможность изменения ветки, которая считается активной веткой разработки. Поскольку инженеры работают в разных ветках внутри цикла разработки, не исключено, что может потребоваться перемещение инсайдеров между этими ветками. В компании относятся к этим сборкам так же, как и к сборкам из ветки RS_PRERELEASE.
Напоминаем, что на канале Dev выпускаются сборки, которые могут содержать довольно неприятные ошибки. Если вам необходима большая стабильность, то рекомендуем перейти на каналы Beta или Release Preview.
Изменения и улучшения
- Начиная с этой сборки настольное приложение Internet Explorer 11 не будет работать. Подробную информацию об этом вы можете найти в официальном блоге.
- Отключена функция «Эко-режим» в «Диспетчере задач», поскольку компания работает над улучшением работы и исправлением некоторых проблем.
Исправления
- Исправлена проблема, возникшая в предыдущей сборке, из-за которой в процессе обновления и на экранах приветствия, отображаемых при первом входе в систему после обновления, для текста неожиданно использовался шрифт Times New Roman.
- Исправлена проблема, из-за которой у некоторых инсайдеров возникала ошибка при попытке запустить «Блокнот» с помощью диалогового окна «Выполнить».
- Исправлена проблема с WSL, из-за которой некоторые Linux-приложения с графическим интерфейсом некорректно запускались с помощью ярлыка, который автоматически добавляется в меню «Пуск».
- Исправлена проблема, из-за которой не работали сценарии спроса или изменения ПИН-кода.
- Исправлена проблема, из-за которой у некоторых инсайдеров функция «Ночной свет» отключалась сразу после включения.
- Исправлена проблема, наблюдавшаяся в предыдущих сборках, из-за которой пользователи могли неожиданно получить ошибку «Не удаётся найти звуковое устройство» при попытке воспроизвести звук на подключенном Bluetooth-динамике.
- Исправлена проблема, из-за которой explorer.exe мог аварийно завершить работу после многократного использования жеста на сенсорной панели для переключения виртуальных рабочих столов.
- Исправлены две проблемы, влиявшие на возможность печати с помощью USB-принтеров.
- Исправлена проблема, из-за которой страница «Центра обновления Windows» могла перестать отвечать на запросы после нажатия на кнопку «Приостановить обновления».
- Исправлена проблема, из-за которой на некоторых устройствах наблюдались сбои с кодом ошибки 0xc1900101. Это обновление решит проблему на некоторых устройствах, однако существует вторая проблема, которая вызывает ошибку с тем же кодом (см. ниже). Инженеры работают над исправлением проблемы.
- Исправлена проблема, из-за которой на некоторых устройствах повторно предлагалось обновление .NET после его установки. Обновившись до этой сборки, вы больше не будете получать повторное обновление .NET. Если у вас возникли проблемы с получением сборки 21387 из-за ожидающего обновления .NET, то вы можете обойти эту проблему, приостановив, а затем возобновив получение обновлений.
- Исправлена проблема, из-за которой на некоторых устройствах возникал GSOD с ошибкой DPC_WATCHDOG_VIOLATION при использовании OneDrive Personal Vault.
- Исправлен сбой ctfmon.exe, возникавший при использовании ATOK (стороннего IME), если в некоторых Win32-приложениях была запущена реконверсия.
Известные проблемы
- Приложение «Камера» сейчас не учитывает настройку яркости по умолчанию, установленную на новой странице в «Параметрах».
- Исследуется проблема, из-за которой элементы Windows Search (в том числе поле поиска в «Проводнике») некорректно отображаются в тёмной теме оформления.
- [Новости и интересы] Исследуется проблема, из-за которой всплывающее окно после нажатия на кнопку на панели задач может мигнуть в левом верхнем углу экрана.
- Инженеры работают над исправлением второй проблемы, которая приводит к сбою при попытке обновления до этой сборки с кодом ошибки 0xc1900101. Если в процессе обновления произойдёт сбой, система автоматически откатится до предыдущей сборки. Пользователям, которые столкнутся с этой проблемой, рекомендуется приостановить получение обновлений до момента, пока не будет выпущена сборка с исправлением.
Желаем вам удачного обновления!

This Friday, Microsoft rolls out Windows 10 Build 21387 to Insiders in the Dev channel. As it was earlier announced, it no longer includes Internet Explorer 11 preinstalled. But to our surprise, yet another feature is now removed from the OS — the Eco Mode option in Task Manager.
Using Eco Mode, you could identify apps that consume high resources. Eco Mode could be used to limit such app’s resource consumption so that the system gives priority to other apps. However, Windows 10 Build 21387 doesn’t include it, as developers are about to refine the experience and address several issues they have learned about from collected feedback.
As for Internet Explorer 11, earlier Microsoft announced that they remove it from the default Windows 10 bundle. Internet Explorer 11 will reach its end of support on June 15, 2021. The company mentioned three main reasons to ditch the old browser in favor of the new Microsoft Edge: better compatibility, streamlined productivity, and better browsing security.
Well, here are the changes in today’s Insider Preview release.
