Windows中的家庭组 可以更轻松地在家庭网络上共享文件和打印机。您可以与家庭组中的其他人共享图片、音乐、视频、文档和打印机。作为一项安全措施，其他人无法更改您共享的文件，除非您授予他们这样做的权限。
当您使用Windows(Windows)设置计算机时，如果您的家庭网络中尚不存在家庭组，则会自动创建一个家庭组。我假设您的一台Windows计算机上已经有一个现有的家庭组。如果家庭组已经存在，您可以加入它，实际上，这将是您唯一的选择。
唯一的问题是，如果原来的计算机现在已经不见了，并且您不再拥有加入家庭组的密码。如果您有另一台计算机已加入该家庭组，则可以按照以下说明查看密码。如果没有，我会提到如何创建一个新的家庭组来替换旧的家庭组。
管理现有家庭组
要将第二台或第三台计算机连接到家庭组，请转到第一台计算机的控制面板，然后单击家庭组(HomeGroup)：
您可以阻止特定文件或文件夹被共享，并且您可以稍后共享其他库。您还可以通过选中将我的图片、音乐和视频流式传输到我的家庭网络上的所有设备(Stream my pictures, music, and videos to all devices on my home network)选项，使您的计算机充当DNLA服务器。(DNLA)您可以使用可以随时更改的密码来帮助保护您的家庭组。
点击查看或打印家庭组密码(View or print the homegroup password)查看密码：
将出现密码。您可以选择打印并分发给与您的家庭组相关的其他人。
在您的另一台Windows计算机上，转到Control Panel > HomeGroup，然后单击立即加入(Join Now)。
创建新的家庭组
如果您无法访问在网络上创建的原始家庭组的密码，则需要创建一个新的家庭组。请注意，这在Windows 7上是可能的。如果您使用的是Windows 8或Windows 10，则实际上没有简单的方法来创建新的家庭组。
因此，如果您陷入不知道家庭组密码并且所有计算机都运行Windows 8或 10 的情况，那么您必须以某种方式将Windows 7计算机接入您的网络才能创建新的家庭组。一旦创建并加入另一台计算机，您可以删除Windows 7计算机，家庭组将继续正常工作。
我读过的唯一其他可能的解决方案是从您的所有计算机中离开家庭组并关闭所有计算机，除了一个。然后重新启动最后一台计算机并打开家庭组对话框，如果幸运的话，您可能会在Windows 10中看到(Windows 10)Create a homegroup选项。同样，确保网络上的所有其他计算机都已关闭。
要在Windows 7中创建新的家庭组，请转到控制面板(Control Panel)，然后转到网络(Network)和共享中心(Sharing Center)。
在View your active networks下，单击网络名称下的Home network。您将看到一个弹出对话框，您可以在其中从几个选项中进行选择。您想将网络位置更改为Public。
现在单击Public network并将其更改回Home network。第二次你这样做，它应该会弹出创建家庭组(Create homegroup)对话框。
您会希望在这里非常快，因为如果您等待超过几秒钟，Windows将检测到原始家庭组并告诉您它无法创建新的家庭组，因为已经存在一个家庭组。如果您快速单击下一步，您将能够创建一个新的家庭组，它将覆盖现有的家庭组。
现在要查看计算机和共享文件，只需转到资源管理器(Explorer)，您就会看到一个名为“家庭组”的选项列出(Homegroup)。
家庭组的概念简化了小型家庭网络上的文件共享。在 2000 和 XP 等旧版Windows中，用户必须提供另一台机器的登录名和密码，或映射网络驱动器才能访问共享内容或设备。
如果您的家庭组有任何问题，请阅读我的 Windows 家庭组终极故障排除指南。如果您仍在运行Windows XP，您可以阅读我关于如何将 XP 机器连接到 Windows 家庭组的帖子。此外，如果您使用Windows 7创建了家庭组，您仍然可以将 Windows 8 或 Windows 10 计算机连接到该 Windows 7 家庭组(connect a Windows 8 or Windows 10 machine to that Windows 7 homegroup)。如果您只是需要在计算机之间共享文件(share files between computers)，请阅读我关于可能比使用家庭组更好的多种方式的文章。享受！
How to Configure a HomeGroup in Windows
A homegroup in Windows makes it easier to share files and printers on a home network. You can share pictures, music, videos, documents, and printers wіth other people in your homegroup. As a security measure, other people can’t change the files that you share, unless you give them permission to do so.
When you set up a computer with Windows, a homegroup is created automatically if one doesn’t already exist on your home network. I assume that you already have an existing homegroup on one of your Windows computers. If a homegroup already exists, you can join it and actually, that’ll be your only option.
The only problem is if the original computer is now gone and you no longer have the password to join the homegroup. If you have another computer that is already joined to that homegroup, you can view the password by following the directions down below. If not, I’ll mention how to create a new homegroup to replace an old homegroup.
Manage Existing HomeGroup
To connect a second or third computer to the homegroup, go to the first computer’s control panel, then click HomeGroup:
You can prevent specific files or folders from being shared, and you can share additional libraries later. You can also make your computer act like a DNLA server by checking the Stream my pictures, music, and videos to all devices on my home network option. You can help protect your homegroup with a password, which you can change at any time.
Click the View or print the homegroup password to view the password:
The password will appear. You may opt to print it and distribute to other people connected to your homegroup.
One your other Windows computers, go to Control Panel > HomeGroup and then click Join Now.
Create New HomeGroup
If you can’t access the password for the original homegroup that was created on your network, you will need to create a new homegroup. Note that this is possible on Windows 7. If you are using Windows 8 or Windows 10, there is literally no easy way to create a new homegroup.
So, if you’re stuck in this situation where you don’t know the homegroup password and all your computers are running Windows 8 or 10, then you’ll have to get a Windows 7 machine onto your network somehow in order to create the new homegroup. Once it has been created and another computer has joined, you can remove the Windows 7 computer and the homegroup will continue working fine.
The only other possible solution I have read about is leaving the homegroup from all of your computers and shutting all of them down, except for one. Then restart that last computer and open the homegroup dialog and if you’re lucky, you might see the Create a homegroup option in Windows 10. Again, make sure all other computers on the network are turned off.
To create a new homegroup in Windows 7, go to Control Panel, then Network and Sharing Center.
Under View your active networks, click on Home network under the network name. You’ll get a popup dialog where you can select from a couple of options. You want to change the network location to Public.
Now click on Public network and change it back to Home network. The second you do this, it should bring up the Create homegroup dialog.
You’ll want to be pretty fast here because if you wait more than a few seconds, Windows will detect the original homegroup and tell you that it cannot create a new homegroup because one already exists. If you click Next quickly, you’ll be able to create a new homegroup, which will override the existing homegroup.
Now to see the computers and shared files, just go to Explorer and you’ll see an option called Homegroup listed.
The concept of homegroup simplifies the file sharing on small scale home networks. In older versions of Windows like 2000 and XP, users had to supply a login and password for another machine or map a network drive to access shared content or devices.
If you’re having any kind of issues with your homegroup, read my ultimate troubleshooting guide for Windows homegroups. If you’re still running Windows XP, you can read my post on how to connect an XP machine to a Windows homegroup. Also, if you created the homegroup using Windows 7, you can still connect a Windows 8 or Windows 10 machine to that Windows 7 homegroup. If you simply need to share files between computers, read my article on the myriad of ways that probably are better than using homegroups. Enjoy!
