在我的笔记本电脑上安装Windows 8.1后，我注意到一个非常大的烦恼：“网络”窗格中没有“(Networks)忘记此网络”("Forget this network")选项。我没有直观的方法来删除由于密码已更改而不再有效的无线网络。您如何解决此问题并在Windows 8.1中删除无线网络？让我们在本教程中找出答案。
它在 Windows 8 中的工作原理
在Windows 8中，当您要删除无线网络(wireless network)时，请打开“网络(Networks)”窗格（本教程说明如何：如何在Windows 8中(Windows 8)管理无线网络连接和配置文件(Manage Wireless Network Connections & Profiles)）并右键单击或按住要删除的网络。
打开一个上下文菜单，其中包括“忘记此网络”("Forget this network")选项。
容易，不是吗？
不幸的是，在Windows 8.1中，您不能再在“(Windows 8.1)网络(Networks)”窗格中单击鼠标右键，并且没有要显示的上下文菜单。但是，您确实有几种新方法可以做同样的事情。
如何在Windows 8.1中忘记(Windows 8.1)无线网络(Wireless Network)，来自网络列表(Networks List)
在Windows 8.1中，您可以在尝试连接无线网络(wireless network)后删除/忘记它。网络必须在范围内并且对您的笔记本电脑或平板电脑(laptop or tablet)可见。如果不是，则无法使用此方法将其删除。如果网络可用，以下是它的完成方式：
在“网络(Networks)”窗格中，选择要删除的网络，然后按“连接(Connect)” 。
如果Windows 8.1无法连接到它，您将看到一条错误消息(error message)和一个显示“忘记网络”("Forget network")的按钮。
按下它，网络就会被删除。您可以重新连接到网络，就像它是新检测到的网络一样。
如何从 PC 设置中忘记Windows 8.1中的(Windows 8.1)无线网络(Wireless Network)
如果您安装了自 2014 年4 月 8(April 8th)日起免费向所有Windows 8.1用户发布的Windows 8.1 更新(Update)，那么您还有另一种忘记无线网络(wireless network)的方法。此方法不适用于没有此更新的Windows 8.1设备。(Windows 8.1)
打开 PC 设置并转到网络(Network)。
在“连接(Connections)”部分，查找 Wi-Fi 和“管理已知网络”("Manage known networks")链接。单击或点击它。
Windows 8.1 显示一个无线网络列表，其中存储连接详细信息。
选择(Select)您要忘记的网络，然后按忘记(Forget)。
Windows 8.1不再存储所选网络，下次连接时，您必须再次输入其密码。
如何在Windows 8.1中通过命令提示符忘记(Command Prompt)无线网络(Wireless Network)
即使网络不在范围内，您也可以在命令提示符的帮助下删除(Command Prompt)Windows 8.1存储的任何无线网络配置文件(network profile)。
以管理员身份启动命令提示符(Command Prompt)并键入以下命令：netsh wlan show profiles.
它将显示Windows 8.1存储的所有无线网络(wireless network)配置文件。如果您使用笔记本电脑或平板电脑超过几周，则该列表可能会很长。
确定要删除的无线网络(wireless network)netsh wlan delete profile name="profile name"配置文件的名称，然后键入以下命令将其删除： 。
例如，我想删除名为swisscom的(swisscom)无线网络配置文件(wireless network profile)，然后键入：。netsh wlan delete profile name="swisscom"
感觉极客？🙂
如何在Windows 8.1中忘记所有(Windows 8.1)无线网络(Wireless Networks)
在某些情况下，您可能需要删除存储在Windows 8.1中的所有(Windows 8.1)无线网络(wireless network)配置文件。幸运的是，您不必一一删除它们。那真是太可怕了。
您所要做的就是输入以下命令：netsh wlan delete profile name=* i=*.
您将看到它在一秒钟内删除所有配置文件。
注意：(NOTE:)该netsh命令具有许多其他参数，而不是本文中共享的参数。如果您想了解更多信息，我建议您阅读TechNet上的文档：无线局域网 (WLAN) 的 Netsh 命令(Netsh Commands for Wireless Local Area Network (WLAN))。
结论
Windows 8.1的初始版本让人很难忘记无线网络，但幸运的是，这个Windows 8.1 更新(Update)修复了这个问题以及其他几个问题。我希望您发现本指南很有用。如果您知道在Windows 8.1中忘记无线网络的其他方法，请不要犹豫，使用下面的评论表分享它们。
How to Delete or Forget Wireless Network Profiles in Windows 8.1
As soon as I installed Windowѕ 8.1 on my laptop, I noticed a pretty big annoyance: the absence of the "Forget this network" option in the Networks pane. I was left with no intuitive way of removing wireless networks that no longer worked because their password has been changed. How do you get around this problem and remove wireless networks in Windows 8.1? Let's find out in this tutorial.
How It Worked in Windows 8
In Windows 8, when you want to remove a wireless network, you open the Networks pane (this tutorial explains how: How to Manage Wireless Network Connections & Profiles in Windows 8) and right-click or press and hold the network you wanted removed.
A contextual menu is opened and it includes the option to "Forget this network".
Easy, isn't it?
Unfortunately, in Windows 8.1 you can no longer right-click in the Networks pane and there is no contextual menu to display. However, you do have several new methods for doing the same thing.
How to Forget a Wireless Network in Windows 8.1, from the Networks List
In Windows 8.1 you can remove/forget a wireless network after you try to connect to it. The network has to be in range and visible to your laptop or tablet. If it isn't, you can't remove it using this method. If the network is available, here's how its done:
In the Networks pane, select the network you want removed and press Connect.
If Windows 8.1 can't connect to it, you will see an error message and a button that says "Forget network".
Press on it and the network is removed. You can reconnect to the network as if it were a newly detected network.
How to Forget a Wireless Network in Windows 8.1, from PC Settings
If you have Windows 8.1 Update installed, which was released for free to all Windows 8.1 users as of April 8th 2014, then you have one more way of forgetting a wireless network. This method doesn't work on Windows 8.1 devices without this update.
Open PC Settings and go to Network.
In the Connections section, look for Wi-Fi and the "Manage known networks" link. Click or tap on it.
Windows 8.1 displays a list with the wireless networks for which its stores connection details.
Select the network you want to forget and press Forget.
The selected network is no longer stored by Windows 8.1 and the next time you connect to it, you will have to enter its password again.
How to Forget a Wireless Network in Windows 8.1, from the Command Prompt
You can remove any wireless network profile stored by Windows 8.1, even if the network is not in range, with the help of the Command Prompt.
Start the Command Prompt as administrator and type the following command: netsh wlan show profiles.
It will display all the wireless network profiles stored by Windows 8.1. The list can be long if you used your laptop or tablet for more than a couple of weeks.
Identify the name of the wireless network profile you want removed, then type the following command to remove it: netsh wlan delete profile name="profile name".
As an example, I wanted to remove a wireless network profile named swisscom and I typed: netsh wlan delete profile name="swisscom".
Feeling geeky? 🙂
How to Forget All Wireless Networks in Windows 8.1
In some scenarios you may need to remove all the wireless network profiles stored in Windows 8.1. Luckily, you don't have to remove them one by one. That would be really awful.
All you have to do is to type this command: netsh wlan delete profile name=* i=*.
You will see it deleting all profiles in less than a second.
NOTE: The netsh command has many other parameters than the ones shared in this article. If you want to learn more about it, I recommend reading its documentation on TechNet: Netsh Commands for Wireless Local Area Network (WLAN).
Conclusion
The initial release of Windows 8.1 made it hard to forget wireless networks but, luckily, this Windows 8.1 Update fixes this problem as well as a couple of other problems. I hope that you have found this guide useful. If you know other ways of forgetting wireless networks in Windows 8.1, don't hesitate to share them using the comments form below.
