有时，我们愚蠢的错误会让我们付出很多代价。例如，想一想您正在处理一些重要工作时不小心按了某个按钮导致系统关闭或重新启动的情况。接下来发生什么？不用^(Needless)说，你失去了所有的工作，不是吗？考虑另一种情况 - 您刚刚在系统上安装了一些Windows 更新^{(Windows Updates)}或应用程序，它需要您重新启动Windows才能进行更改。您不想执行此操作，因为您正在处理一些重要的事情。如果这一切让您感到困扰，请尝试ShutdownBlocker。

ShutdownBlocker是一款适用于^{(ShutdownBlocker)}Windows的免费软件工具，可让您阻止Windows中的任何关机、重启或注销命令。这个小巧而巧妙的应用程序可以防止设计不佳的安装程序（缺少“稍后重新启动”选项的安装程序），甚至Windows也会自行重新启动。

ShutdownBlocker 的工作原理

该实用程序应用程序通过注册ShutdownBlockReasonCreate()原因和反对WM_QUERYENDSESSION消息来工作。此外，要使其按设计运行，您需要以管理权限运行应用程序并授予对它的完全访问权限。该应用程序的便携式版本可用，您只需运行 .exe 文件即可。

如果您没有以管理权限启动Shutdownblocker ，那么您将看不到某些功能。^{(Shutdownblocker)}例如，您必须以管理员权限运行它，然后才能检查拦截 shutdown.exe 和MusNotification.exe的选项。

下载后首次运行应用程序时，应用程序的主窗口会出现在屏幕上，显示 2 个主要选项，如下面的屏幕截图所示。

1. 堵塞
2. 允许。

该程序必须保持运行才能工作。您可以使用“隐藏”按钮、退出键或应用程序的右上角关闭按钮将应用程序最小化到通知托盘。或者，您可以隐藏托盘图标（在设置中）以实现完全不可见的操作。

ShutdownBlocker的此操作不会以任何方式干扰您系统的其他设置。您可以手动关闭或重新启动系统。此外，您会收到Shutdownblocker正在运行的警告，该操作类似于您在其他应用程序打开时看到的操作，您选择“仍然关闭”选项将它们全部关闭。

Shutdownblocker还从其系统托盘图标中提供了一个右键单击“允许关机”选项。^(Allow)

您可以为ShutdownBlocker^{(ShutdownBlocker)}选择或配置不同的选项，例如 -

• 在没有托盘图标的情况下运行
• 从 Windows 开始
• 显示关键信息
• 添加快捷方式。

只需^(Simply)点击主屏幕底部的“设置”按钮，然后检查上面列出的选项。^(Settings)

如果您在删除 Shutdownblocker 的保护时遇到问题，请重新启动，以管理员身份启动它并单击Allow > Quit，然后输入shutdown.exe /?在命令行中确认它是否有效。

ShutdownBlocker, blocks accidental Shutdown or Restart of computer

At times our silly mistakes can cost us a lot. For examplе, think of a situation where you are in the middle of some іmportant work and you aсcidentаlly preѕs some button that causes a sуstem shut down or restаrt. What happens next? Needlesѕ to mention, you lose all the work, isn’t it? Consider another situation – you have just finished installing some Windows Updates or an app on your system and it requires you to restart Windows to make the changes. You do not want to perform this aсtion since you are working on something important. If all this bothers yоu, try ShutdownBlocker.

ShutdownBlocker is a freeware tool for Windows which allows you to prevent any shutdown, restart or log off commands in Windows. The small, ingenious app offers protection against poorly designed installers (the ones lacking a ‘restart later’ option), and even Windows restarts itself.

How ShutdownBlocker works

The utility app works by registering a ShutdownBlockReasonCreate() reason and objecting to WM_QUERYENDSESSION messages. Also, to enable it to function as designed, you need to run the app with administrative privileges and give full access to it. The portable version of the app is available and you can simply run the .exe file.

If you do not launch Shutdownblocker with administrative privileges then certain features will not be visible to you. For example, you must be running it with administrative access before you can check the option to intercept shutdown.exe and MusNotification.exe.

When you first run the app after downloading it, the main window of the app appears on your screen displaying 2 main options as shown in the screenshot below.

1. Block
2. Allow.

The program must be kept running to work. You can minimize the app to the notification tray by using the ‘Hide’ button, the escape key, or the app’s upper right close button. Optionally you can hide the tray icon (in settings) for completely invisible operation.

This operation of ShutdownBlocker does not in any way interfere with other settings of your system. You can manually shut down or restart your system. Also, you’ll be warned that Shutdownblocker is running, an action similar to the one you see when other apps are open and you choose “shut down anyway” option to close them all.

Shutdownblocker also offers a right-click “Allow shutdowns” option from its system tray icon.

You can select or configure different options for ShutdownBlocker like-

• Run without the tray icon
• Start with Windows
• Display critical messages
• Add shortcuts.

Simply, hit the Settings button, seen at the bottom of the main screen and check the options listed above.

If you have problems removing Shutdownblocker’s protection, reboot, launch it as an administrator and click Allow > Quit, then enter shutdown.exe /? at the command line to confirm that it works.
