Что такое «Servicing stack update», обновления служебного стека Windows 10

Скорее всего, вы уже сталкивались с обновлениями служебного стека (Servicing stack update, SSU) в роли системного администратора или конечного пользователя. Microsoft использует довольно расплывчатые описания применительно к данному типу обновлений.

Например, при проверке описания критического обновления KB4343669 для Windows 10 версии 1803 вы увидите следующую фразу «This update makes stability improvements for the Windows 10, version 1803 servicing stack» (Это обновление включает улучшения стабильности для служебного стека Windows 10 версии 1803), которое создает больше вопросов, чем ответов.

Для KB4132216 имеются дополнительные сведения об обновлении, но Microsoft никогда подробно не объясняла, для чего предназначены обновления служебного стека.

Разработчики ОС Windows классифицируют обновления служебного стека как критические обновления системы.

Ответы могут быть получены на японском сайте поддержки Microsoft Windows в виде этой статьи. Статья написана на японском языке, но старый добрый Google Translate дает некоторое представление о её содержании.

Проверить наличие обновления можно в меню Панель управления > Программы > Программы и компоненты > Просмотр установленных обновлений.

В статье представлена следующая информация:

• Что такое обновление служебного стека (Servicing stack update)?
• Подробная информация о применении данного типа обновлений.
• Как узнать, какая версия обновлений служебного стека является актуальной для данной версии Windows.
• Что делать, если обновление нельзя применить к системе.

Что такое обновление служебного стека?

Обновление служебного стека (Servicing stack update) обновляет компоненты службы Component Based Servicing (CBS), которая обрабатывает процесс установки операционной системы.

Накопительные обновления в Windows 10 включают в себя только самые новые версии файлов или новые файлы системы при установке. Обновления служебного стека должны быть отделены от процесса, поскольку они являются обязательными.

Установив обновления, можно улучшить следующее:

• Добиться установки последних обновлений, потому что они могут требовать определенную версию служебного стека.
• Повысить надежность процесса обновления.
• Улучшить производительность.
• Получить другие улучшения, упоминаемые в описании отдельных обновлений служебного стека.

Когда вы устанавливаете новое обновление служебного стека на устройстве Windows 10, все модули компонента CBS обновляются. Windows 10 блокирует удаление обновлений служебного стека на компьютерах Windows и единственный вариант, которым могут воспользоваться пользователи и администраторы при возникновении проблем после установки нового обновления служебного стека — это восстановление старой версии операционной системы.

Трудно узнать, какое обновление служебного стека является последним для конкретной версии Windows. Японская группа поддержки предлагает два способа узнать об этом:

• Запустите поиск на веб-сайте поддержки Microsoft по запросу Servicing stack update Windows 10 и просмотрите результаты.
• Настройте виртуальную среду и проверьте, какой пакет обновления стека установлен.

Корпорация Майкрософт не поддерживает публичный список обновлений служебного стека для консультации по актуальной версии обновления стека обслуживания для конкретной версии Windows.

Обновления служебного стека могут иметь предварительные условия для установки. Если требуемый пакет стека не установлен, Windows выдает сообщение об ошибке «Это обновление не может быть применено к вашему компьютеру».

Событие записывается в журнал Windows с ошибкой 2149842967 в качестве причины. Ошибка «переводится» как «WU_E_NOT_APPLICABLE». Другими словами, обновление невозможно установить, поскольку отсутствует необходимое предварительное обновление.

Заключение

Согласно Microsoft, обновления служебного стека обновляют только компоненты CBS. В японской статье содержится некоторое представление о текущем процессе обновления.

Servicing stack updates

Applies to

• WindowsВ 10, Windows 8.1, Windows 8, Windows 7

What is a servicing stack update?

Servicing stack updates provide fixes to the servicing stack, the component that installs Windows updates. Additionally, it contains the «component-based servicing stack» (CBS), which is a key underlying component for several elements of Windows deployment, such as DISM, SFC, changing Windows features or roles, and repairing components. The CBS is a small component that typically does not have updates released every month.

Why should servicing stack updates be installed and kept up to date?

Servicing stack updates improve the reliability of the update process to mitigate potential issues while installing the latest quality updates and feature updates. If you don’t install the latest servicing stack update, there’s a risk that your device can’t be updated with the latest Microsoft security fixes.

When are they released?

Servicing stack update are released depending on new issues or vulnerabilities. In rare occasions a servicing stack update may need to be released on demand to address an issue impacting systems installing the monthly security update. Starting in November 2018 new servicing stack updates will be classified as «Security» with a severity rating of «Critical.»

You can find a list of servicing stack updates at Latest servicing stack updates.

What’s the difference between a servicing stack update and a cumulative update?

Both Windows 10 and Windows Server use the cumulative update mechanism, in which many fixes to improve the quality and security of Windows are packaged into a single update. Each cumulative update includes the changes and fixes from all previous updates.

Servicing stack updates must ship separately from the cumulative updates because they modify the component that installs Windows updates. The servicing stack is released separately because the servicing stack itself requires an update. For example, the cumulative update KB4284880 requires the May 17, 2018 servicing stack update, which includes updates to Windows Update.

Is there any special guidance?

Microsoft recommends you install the latest servicing stack updates for your operating system before installing the latest cumulative update.

Typically, the improvements are reliability and performance improvements that do not require any specific special guidance. If there is any significant impact, it will be present in the release notes.

Installation notes

• Servicing stack updates contain the full servicing stack; as a result, typically administrators only need to install the latest servicing stack update for the operating system.
• Installing servicing stack update does not require restarting the device, so installation should not be disruptive.
• Servicing stack update releases are specific to the operating system version (build number), much like quality updates.
• Search to install latest available Servicing stack update for Windows 10.
• Once a servicing stack update is installed, it cannot be removed or uninstalled from the machine.

Simplifying on-premises deployment of servicing stack updates

With the Windows Update experience, servicing stack updates and cumulative updates are deployed together to the device. The update stack automatically orchestrates the installation, so both are applied correctly. Starting in February 2021, the cumulative update will include the latest servicing stack updates, to provide a single cumulative update payload to both Windows Server Update Services (WSUS) and Microsoft Catalog. If you use an endpoint management tool backed by WSUS, such as Configuration Manager, you will only have to select and deploy the monthly cumulative update. The latest servicing stack updates will automatically be applied correctly. Release notes and file information for cumulative updates, including those related to the servicing stack, will be in a single KB article. The combined monthly cumulative update will be available on Windows 10, version 2004 and later starting with the 2021 2C release, KB4601382.

Show windows side by side in windows 10

I’ve always right clicked on the taskbar and selected «Show windows side by side.» Now on my Windows 10 laptop, the two windows display very narrow and only on one half of the screen. Is there something I can do to make two documents display across the entire width of the screen?

***Post moved by the moderator to the appropriate forum category.***

Aero Snap is one of the interesting features of Windows 10 that automatically arrange windows by tiles or side by side. Here are the different methods on how you can customize your windows view on your desktop using Aero Snap:

Method 1: Side by side windows.

This method will make each window take half of the computer screen allowing you to arrange it side by side.

1. Press and hold Windows logo key.

2. Press the left or right arrow key.

Method 2: Vertical Snap

You can also use Aero Snap to maximize or minimize the open windows on your desktop.

1. Press and hold Windows logo key + Up arrow key to snap the window to the top halves of the screen.

2. Press and hold Windows logo key + Down arrow key to snap the window to the bottom halves of the screen.

3. Press Windows logo key + Up arrow key twice to maximize the window.

4. Press Windows logo key + Down arrow key twice to minimize the window.

Method 3: 2×2 Snap

2×2 Snap will let you put up to 4 windows on your desktop using a combination of the Windows logo key + left/right/up/down arrow key.

Based on this thread and another in a different forum, the problem with side by side and stacked windows not working is due to a bug whereby various apps come up and appear to be on the desktop. When you do a side by side, you might have only 2 windows you see — everything else is minimised — but after the operation you wind up with screen real estate as if you were sharing with 2 3 4 or more shadow apps that do not show up.

If you use task manager, you will see phantom apps — e.g. calculator, calendar, skype, all of these come from C:\Program Files\WindowsApps. You might also see SystemSettings. If you kill these, you will generally find that Side-By-Side and Stacked windows behave as expected. Rarely, you may also have to stop/start (re-cycle explorer).

A guaranteed fix is to logoff (not reboot — just logoff) and login. Things work ok until you use a few modern apps and then they start to leak and screw things up.

Randomish8 (from other forum) may have reduced the problem to ApplicationFrameHost.exe as opposed to the mix of Apps I have stumbled across. I have not run into it yet but his solution may be more comprehensive.

I use Cygwin and I have a script that looks for processes in C:\Program Files\WindowsApps or named Systemsettings and kills those. If that is not sufficient I have another script that also recycles Explorer. So far that has always fixed things. I will try to look for ApplicationFrameHost.exe instead to see if that works.

In any event, you are not going nuts. The windows arrangement features works expected and as they always did when you log in and eventually degenerate as apps start to leak. Microsoft is definitely on the hook to fix this but in the meantime, there are ways of coping.

‘Show windows stacked’ and ‘Show windows side by side’ does the same so one of them must be broken. I believe that the latter.

I’m talking about my PC in this comment.

It looks like Show windows stacked and Show windows side by side are both broken in Windows 10. Due to the Aero corner snapping feature (4 quadrants), they broke it.
