Windows Homegroup is great for sharing documents, pictures, and printers between computers on your home network. If you’ve had it set up for a while, you may have noticed that the ghosts of old computer hang around in your Homegroup list. Here’s how to banish them.
Windows Homegroup非常适合在家庭网络中的计算机之间共享文档，图片和打印机。 如果您已经设置了一段时间，那么您可能已经注意到，旧计算机的幽灵在您的家庭组列表中徘徊。 这是消除它们的方法。
If you’re on a home network and want an easy way to share files and printers between computers without monkeying around with Windows network settings, Homegroup is a great feature. All you have to do is create a homegroup on one computer (Windows 7 or later), note the password it generates, and then join that Homegroup on other computers. You get to select what types of files each computer shares during setup and that’s it. If you get rid of an old computer, though, Homegroup has no way of knowing whether the computer is no longer on the network or just unavailable. Removing a computer from your Homegroup is also super easy. It’s just that, for some reason, you can’t do it through the Homegroup control panel. But we’ve got you covered.
如果您在家庭网络中，并且想要一种简单的方法来在计算机之间共享文件和打印机，而又不浪费Windows网络设置，则Homegroup是一项很棒的功能。 您要做的就是在一台计算机(Windows 7或更高版本)上创建一个家庭组，记下它生成的密码，然后在其他计算机上加入该家庭组。 您可以选择在安装过程中每台计算机共享的文件类型，仅此而已。 但是，如果您摆脱了旧计算机，Homegroup将无法知道计算机是否不再在网络上或仅不可用。 从家庭组中删除计算机也非常容易。 仅仅是出于某种原因，您无法通过Homegroup控制面板执行此操作。 但是我们已经覆盖了您。
Start by opening File Explorer on any computer connected to the Homegroup. In the navigation pane on the left, scroll down and then expand the Homegroup folder. Note that if you’re on a computer running Windows 8 or later and you’re signed in with a Microsoft account, you’ll also see a user folder under the Homegroup folder that you’ll need to expand. If you’re on a Windows 7 computer, you’ll just see the Homegroup folder.
首先在连接到家庭组的任何计算机上打开文件资源管理器。 在左侧的导航窗格中，向下滚动，然后展开Homegroup文件夹。 请注意，如果您使用的是运行Windows 8或更高版本的计算机，并且已使用Microsoft帐户登录，那么您还将在需要扩展的Homegroup文件夹下看到一个用户文件夹。 如果您使用的是Windows 7计算机，则只会看到Homegroup文件夹。
In that folder, you’ll see a list of the PCs in the Homegroup. PCs that are unavailable on the network are dimmed. Here’s a caveat, though. If a computer is asleep, turned off, or just disconnected from the network, it will show as unavailable. Make sure that you’re removing a computer that you actually want to remove. If you’re not sure, make sure that all your current computers are turned on, not asleep, and are connected to the network. That said, if you do end up removing the wrong computer from your Homegroup, it’s easy enough to add it again.
在该文件夹中，您将看到家庭组中的PC列表。 网络上不可用的PC呈灰色。 不过，请注意。 如果计算机处于睡眠状态，关机或刚刚断开网络连接，则计算机将显示为不可用。 确保要删除实际上要删除的计算机。 如果不确定，请确保当前所有计算机都已打开而不是处于睡眠状态，并且已连接到网络。 也就是说，如果您最终从家庭组中删除了错误的计算机，那么再次添加它就很容易了。
Click the name of any unavailable PC.
单击任何不可用的PC的名称。
On the right, click the “Remove <computername> from the homegroup” link. You won’t get any confirmation about the removal; it will just happen.
在右侧，单击“从家庭组中删除<计算机名>”链接。 您不会收到有关删除的任何确认； 它只会发生。
And that’s it. The computer will no longer be listed in the Homegroup. Why Microsoft didn’t include the ability to remove a computer in the Homegroup control panel, there’s no telling. But it’s easy to get those old computers off your list once you know where to look.
就是这样。 该计算机将不再列在家庭组中。 为什么Microsoft在Homegroup控制面板中没有包括删除计算机的功能，这没有什么可说的。 但是，一旦您知道要查找的位置，就很容易将那些旧计算机从清单中删除。
