So you notice you are missing icons in the System Tray, like the clock or volume icons, and then you realize that you simply can’t enable them because the checkboxes are grayed out. So what do you do?

因此，您注意到系统托盘中缺少图标，例如时钟或音量图标，然后您意识到，由于复选框为灰色，因此您根本无法启用它们。 所以你会怎么做？

The problem exists because system policies were set that probably shouldn’t be, but either way your icons are missing:

存在此问题是因为设置了可能不应该设置的系统策略，但是无论哪种方式都缺少图标：

Normally you can re-enable the items by right-clicking on the Taskbar, choosing properties and going to the Notification Area tab:

通常，您可以通过右键单击任务栏，选择属性并转到“通知区域”选项卡来重新启用项目：

But they are grayed out… what’s up with that?

但是它们变灰了……这是怎么回事？

Note: I’m assuming you already did the normal Windows fix-it technique of rebooting, and the problem still exists.

注意：我假设您已经执行了正常的Windows Fix-it重启技术，但问题仍然存在。

Fix for Notification Icons are Missing and Checkboxes are Grayed Out

修复了通知图标丢失和复选框呈灰色的问题

You can solve all of these problems by looking in two separate places in the registry, and then deleting a bunch of keys in each location. We’ll detail all of the keys here, but you can skip down a bit for a downloadable registry hack file.

您可以通过在注册表中的两个单独的位置中查找，然后删除每个位置中的一堆**来解决所有这些问题。 我们将在此处详细说明所有键，但您可以略过一点以下载可下载的注册表黑客文件。

Open up regedit.exe through the start menu search or run box, and then browse down to the following key:

通过开始菜单搜索或运行框打开regedit.exe，然后向下浏览至以下键：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer

If you see any of the following key names in the right-hand pane, delete them:

如果在右侧窗格中看到以下任何键名称，请删除它们：

• NoTrayItemsDisplay
  NoTrayItemsDisplay
• HideClock
  隐藏时钟
• HideSCAPower
  HideSCAPower
• HideSCAVolume
  HideSCA卷
• NoAutoTrayNotify
  NoAutoTrayNotify
• HideSCANetwork
  HideSCANetwork

After deleting the values in that pane, browse to the following key and then repeat the process:

删除该窗格中的值后，浏览至以下键，然后重复该过程：

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer

HKEY_CURRENT_USER \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer

You’ll have to logout and then back in, and then most likely go back into taskbar properties and re-check the boxes for each.

您必须先注销然后再登录，然后很可能返回到任务栏属性，然后重新选中每个复选框。

What if the Volume Icon Still Doesn’t Work?

如果音量图标仍然不起作用怎么办？

Over the last year, many people have reported a related problem to me: They just have no volume icon… and also no sound.

去年，许多人向我报告了一个相关的问题：他们只是没有音量图标……也没有声音。

If you encounter this problem, you should immediately open Device Manager and make sure that there are no exclamation points next to your sound card, because the problem is likely that your sound card driver isn’t working.

如果遇到此问题，应立即打开“设备管理器”，并确保声卡旁边没有感叹号，因为该问题可能是声卡驱动程序无法正常工作。

If there are exclamation points, or the sound card is missing and there are a bunch of “Unknown devices”, you usually need to reload the sound card driver from the manufacturer, but sometimes you can right-click on the device and choose to “Update Driver”.

如果有感叹号，或者声卡丢失，并且有一堆“未知设备”，通常需要从制造商处重新加载声卡驱动程序，但是有时您可以右键单击该设备并选择“更新驱动程序”。

Note: I’ve also run into this issue with Toshiba and Acer laptops, the solution for those usually being a BIOS update.

注意：东芝和Acer笔记本电脑也遇到了这个问题，通常通过BIOS更新来解决这些问题。

If you still have problems, head over to our forum and ask your question over there.

如果您仍然有问题，请前往我们的论坛并在那询问您的问题。

Important Note: Numerous people have reported to me that this problem happens much less after installing Service Pack 1, so you should probably make sure you are all patched up as well.

重要说明：许多人向我报告说，在安装Service Pack 1之后，此问题的发生率将大大降低，因此您可能应该确保还对所有这些补丁进行了修补。
