如果您想将 Windows 7 启动到安全模式，(Safe Mode,)这意味着您的计算机可能有问题。安全模式(Safe Mode)可以帮助您诊断，有时甚至可以修复问题。但是，在这样做之前，您必须首先知道如何将您的 Windows 7 计算机启动到安全模式(Safe Mode)。在本文中，我们将讨论什么是安全模式(Safe Mode)以及它是如何工作的，我们将引导您了解在Windows 7中进入和退出安全模式的方法：
1.在Windows 7启动过程中按住F8键(F8 key)
当您无法正常启动时，进入Windows 7 安全模式(Windows 7's Safe Mode)的最快方法是在 PC 启动时按住键盘上的F8 键(F8 key)，然后立即打开它。一些较旧的系统可能会停止加载操作系统(operating system)并显示有关执行此操作的键卡住的错误消息。(error message)对于这些情况，请快速点击F8 键(F8 key)而不是按住它。它会打开“高级启动选项(Advanced Boot Options)”窗口，您可以在其中选择启动到安全模式、带网络连接的(Safe Mode, Safe Mode with Networking,)安全模式和带命令提示符(Safe Mode with Command Prompt)的安全模式，以及其他几个选项。使用箭头键选择安全模式(Safe Mode)您喜欢，然后按Enter。
注意(NOTE)：如果您在安装新驱动程序或更改设置后无法正常启动 Windows 7 计算机，您可能需要先尝试“最后一次正确配置”("Last Known Good Configuration")选项，然后再尝试安全模式(Safe Mode)。理想情况下，这会重新启动 Windows 7，就像问题程序或选项(problem program or option)到位之前一样。
2. 使用系统配置工具(msconfig.exe) 将(System Configuration tool)Windows 7引导至安全模式(Mode)
另一种选择是使用系统配置工具(System Configuration tool)。最快的方法是在“开始”菜单(Start Menu)的搜索字段中键入命令msconfig，然后单击msconfig结果。
系统配置(System Configuration)打开后，转到引导(Boot)选项卡。在那里您可以找到一个名为“启动选项(Boot options)”的设置部分和一个名为“安全启动”的选项。("Safe boot.")启用它。
检查“安全启动”("Safe boot")条目后，单击“确定(OK)”并确认您要立即重新启动还是稍后重新启动。
下次启动 Windows 7 时，它将加载安全模式(Safe Mode)。
请注意，此设置在某种程度上是永久性的，直到您将其更改回来。您必须返回系统配置(System Configuration)工具，取消选中“安全启动”("Safe boot")选项，点击确定(OK)，然后再次重新启动Windows 7 PC 以退出安全模式(Safe Mode)。
3. 使用命令提示符(Command Prompt)启动Windows 7的安全模式
使用管理员权限启动命令提示符窗口。(Command Prompt window)在“开始”菜单(Start Menu)的搜索字段中搜索“cmd”，右键单击结果并从打开的上下文菜单中选择“以管理员身份运行” 。("Run as administrator")
如果您收到UAC 提示(UAC prompt)以批准具有管理员权限的运行，请回答是。(Yes)根据您想要的安全启动模式(boot mode)运行以下命令之一：(Run one)
- 安全模式(Safe Mode)："bcdedit /set {default} safeboot minimal"
- 带网络的安全模式(Safe Mode with Networking)："bcdedit /set {default} safeboot network"
- 带命令提示符的安全模式(Safe Mode with Command Prompt)："bcdedit /set {default} safebootalternateshell yes"
重新启动您的Windows 7系统，它将进入安全模式(Safe Mode)。在这个阶段，每次开机都会进入Windows 7的安全模式(Safe Mode)。完成会话后，运行此命令以能够再次正常启动Windows 7："bcdedit /deletevalue {default} safeboot"
在下次重新启动Windows 7时，您将获得完整的操作系统(operating system)。
4. 使用Windows 7 安装驱动器(installation drive)和命令提示符(Command Prompt)
使用Windows 7安装DVD引导您的计算机。看到设置向导(setup wizard)的第一个屏幕（如下屏幕截图所示）后，同时按下键盘上的Shift + F10键。它触发命令提示符(Command Prompt)窗口的启动。
在命令提示符(Command Prompt)窗口中，运行以下命令：_"_bcdedit /set {default} safeboot minimum"。然后按键盘上的Enter 。您会收到消息“操作已成功完成”。
现在关闭命令提示符(Command Prompt)并关闭Windows 7 安装向导(installation wizard)。向导会询问您是否确定要取消安装。说是，然后等待(Say Yes and wait)计算机重新启动。
一旦您的计算机重新启动，它应该会自动启动到安全模式(Mode)。在这个阶段，每次启动时，您都会获得Windows 7中的安全模式(Safe Mode)。完成安全模式(Safe Mode)会话后，运行此命令以再次正常启动："bcdedit /deletevalue {default} safeboot"
在下次重新启动Windows 7时，您将获得完整的操作系统(operating system)。
5. 使用Windows 7 修复盘(repair disk)和命令提示符(Command Prompt)
启动进入安全模式(Mode)的另一个选择是使用修复盘(repair disk)。首先启动(Boot)到修复光盘(repair disc)。在主窗口中，选择“命令提示符”。("Command Prompt.")
它会启动一个命令提示符(Command Prompt)窗口，您可以在其中运行多个命令。输入(Enter one)以下命令之一，具体取决于您想要的安全模式：(Safe Mode)
- 安全模式(Safe Mode)："bcdedit /set {default} safeboot minimal"
- 带网络的安全模式(Safe Mode with Networking)："bcdedit /set {default} safeboot network"
- 带命令提示符的安全模式(Safe Mode with Command Prompt)："bcdedit /set {default} safebootalternateshell yes"
关闭命令提示符(Command Prompt)窗口，然后在主系统恢复选项(System Recovery Options)窗口上按重新启动。(Restart)它将 Windows 7 重新启动到安全模式(Safe Mode)。
在这个阶段，每次启动时，都会启动Windows 7 安全模式(Safe Mode)。完成安全模式(Safe Mode)会话后，运行此命令以再次正常启动："bcdedit /deletevalue {default} safeboot"
在下次重新启动Windows 7时，您将获得完整的操作系统(operating system)。
Windows 7 中的安全模式
当被告知进入安全模式(Safe Mode)时，Windows仅加载运行所需的最基本要素（最少(minimal set)的驱动程序和服务集）。除了Windows(Windows)的核心程序和功能之外，您无权访问任何内容，其中不包括网络设备的驱动程序——这意味着您通常无法在标准安全模式下(Safe Mode)访问 Internet 。在安全模式下(Safe Mode)，您可能会觉得您的屏幕看起来很不稳定并且与通常情况不同。这是因为它已设置为以最低的图形设置和Windows支持的最低分辨率运行。在Windows 7的情况下，即 800 x 600 像素。
此外，您可能会注意到桌面的所有四个角都以文本形式写有“安全模式” 。("Safe Mode")此外，当您在Windows 7中启动进入(Windows 7)安全模式(Safe Mode)时，总是会看到Windows 帮助和支持(Windows Help and Support)工具，它会解释什么是安全模式(Safe Mode)以及如何使用它。
再一次记住，安全模式(Safe Mode)不会加载任何应该在启动时运行的第三方服务或程序。它仅加载Windows 7运行所需的核心服务和功能。
不同种类的安全模式(Safe Mode)有什么作用？
您可能已经注意到，除了普通的旧安全模式(Safe Mode)之外，您还有几个选项。
如果您需要互联网来更新驱动程序或其他程序，请确保在启动安全模式时选择(Safe Mode)“带网络的安全模式”("Safe Mode with Networking")选项。它会加载使用网卡或调制解调器(network card or modem)所需的驱动程序，以便您可以在安全模式下(Safe Mode)访问互联网或其他联网计算机。
或者，如果您更喜欢使用命令提示符(Command Prompt)，您可能希望使用“带命令提示符的安全模式”("Safe Mode with Command Prompt")选项，以便加载执行此操作所需的工具。使用命令提示符(Command Prompt)的高级用户可能已经知道为什么这很有帮助。但是，即使是初学者也可以受益于在安全模式下使用(Safe Mode)命令提示符(Command Prompt)。只需几个简单的命令，他们就可以更快地浏览计算机。
您(Did)是否进入了 Windows 7 的安全模式(Mode)？
恭喜！现在您知道如何将任何Windows 7计算机启动到安全模式(Safe Mode)。它可以成为各种尴尬情况的救星，我们很想听听您关于使用安全模式(Safe Mode)进行故障排除的任何故事。
5 ways to boot Windows 7 into Safe Mode
If you want to boot Windows 7 into Safe Mode, it means that there is probably something wrong with your computer. Safe Mode can help you diagnose and sometimes even repair issues. However, before doing so, you must first know how to boot your Windows 7 computer into Safe Mode. In this article, we discuss what Safe Mode is and how it works, and we walk you through the methods of getting in and out of it, in Windows 7:
1. Hold down the F8 key during the Windows 7 boot
The fastest method for entering Windows 7's Safe Mode when you cannot boot normally, is to hold down the F8 key on your keyboard while your PC is starting, immediately after turning it on. Some older systems may stop loading the operating system and display an error message about a stuck key for doing this. For those cases tap the F8 key rapidly instead of holding it down. It brings up the Advanced Boot Options window, in which you can choose to boot into Safe Mode, Safe Mode with Networking, and Safe Mode with Command Prompt, among several other options. Use the arrow keys to select the Safe Mode you prefer and press Enter after that.
NOTE: If you are unable to start your Windows 7 computer normally after installing new drivers or changing settings, you may want to go down and try the "Last Known Good Configuration" option before trying Safe Mode. Ideally, this reboots Windows 7 as it was before the problem program or option was put in place.
2. Use the System Configuration tool (msconfig.exe) to boot Windows 7 into Safe Mode
Another option is to use the System Configuration tool. The fastest way to do that is to type the command msconfig in the search field from the Start Menu and then click the msconfig result.
Once System Configuration opens, go to the Boot tab. There you find a settings section called Boot options and an option called "Safe boot." Enable it.
After you check the "Safe boot" entry, click OK and confirm whether you would like to restart now or later.
The next time you start Windows 7, it is going to load the Safe Mode.
Note that this setting is somewhat permanent until you change it back. You must return to the System Configuration tool, uncheck the "Safe boot" option, hit OK and then restart your Windows 7 PC again to get back out of Safe Mode.
3. Use the Command Prompt to start Windows 7's Safe Mode
Start a Command Prompt window with administrator permissions. Search for "cmd" in the search field of the Start Menu, right-click on the result and choose "Run as administrator" from the context menu that opens.
Answer Yes if you get a UAC prompt to approve the run with administrator permissions. Run one of the following commands depending on which safe boot mode you want:
- Safe Mode: "bcdedit /set {default} safeboot minimal"
- Safe Mode with Networking: "bcdedit /set {default} safeboot network"
- Safe Mode with Command Prompt: "bcdedit /set {default} safebootalternateshell yes"
Restart your Windows 7 system, and it is going to start into Safe Mode. At this stage, every time you boot, you get the Safe Mode of Windows 7. After you finish your session, run this command to be able to boot Windows 7 normally again: "bcdedit /deletevalue {default} safeboot"
At the next restart of Windows 7, you get the full operating system.
4. Use a Windows 7 installation drive and the Command Prompt
Use a Windows 7 installation DVD to boot your computer. Once you see the first screen of the setup wizard (the one shown in the screenshot below), press simultaneously on the Shift + F10 keys from your keyboard. It triggers the launch of a Command Prompt window.
In the Command Prompt window, run this command: _"_bcdedit /set {default} safeboot minimal". Then press Enter on your keyboard. You get the message "The operation completed successfully."
Now close Command Prompt and also close the Windows 7 installation wizard. The wizard asks if you are sure about canceling the installation. Say Yes and wait for the computer to reboot.
Once your computer restarts, it should automatically boot into Safe Mode. At this stage, every time you boot, you get the Safe Mode in Windows 7. After you finish your Safe Mode session, run this command to be able to boot normally again: "bcdedit /deletevalue {default} safeboot"
At the next restart of Windows 7, you get the full operating system.
5. Use a Windows 7 repair disk and the Command Prompt
Another option to boot into Safe Mode is to use a repair disk. Boot into the repair disc first. On the main window, choose "Command Prompt."
It starts a Command Prompt window where you run several commands. Enter one of the following commands, depending on which Safe Mode you want:
- Safe Mode: "bcdedit /set {default} safeboot minimal"
- Safe Mode with Networking: "bcdedit /set {default} safeboot network"
- Safe Mode with Command Prompt: "bcdedit /set {default} safebootalternateshell yes"
Close the Command Prompt window and then press Restart on the main System Recovery Options window. It restarts Windows 7 into Safe Mode.
At this stage, every time you boot, you start the Windows 7 Safe Mode. After you finish your Safe Mode session, run this command to be able to boot normally again: "bcdedit /deletevalue {default} safeboot"
At the next restart of Windows 7, you get the full operating system.
Safe Mode in Windows 7
When told to enter Safe Mode, Windows only loads the barest essentials needed to function (a minimal set of drivers and services). You do not have access to anything but the core programs and functions of Windows, which do not include the drivers for your networking devices - meaning you usually cannot access the internet while in the standard Safe Mode. While in Safe Mode, you might feel that your screen looks wonky and different than it usually does. It is because it has been set to run at the lowest possible graphics settings and the minimum resolution supported by Windows. In the case of Windows 7, that is 800 x 600 pixels.
Also, you might notice that all four corners of the desktop have "Safe Mode" written in text. Additionally, when you boot into Safe Mode in Windows 7, you are always greeted by the Windows Help and Support tool, explaining what Safe Mode is and how to use it.
Once again, remember that Safe Mode does not load any third-party services or programs that were supposed to run at startup. It loads only the core services and features needed by Windows 7 to run.
What do the different kinds of Safe Mode do?
You might have noticed that you have a couple of options beyond the plain old Safe Mode.
If you need the internet to update drivers or other programs, make sure to choose the "Safe Mode with Networking" option when initiating Safe Mode. It loads the drivers necessary to use your network card or modem so that you can access the internet or other networked computers while in Safe Mode.
Alternatively, if you prefer to use the Command Prompt, you might want to use the "Safe Mode with Command Prompt" option so that it loads the tools necessary to do this. The advanced users who use the Command Prompt probably already know why this is helpful. However, even beginners can benefit from using Command Prompt in Safe Mode. With just a few simple commands, they can navigate the computer more quickly.
Did you enter Windows 7's Safe Mode?
Congratulations! Now you know how to boot any Windows 7 computer into Safe Mode. It can be a lifesaver for all sorts of embarrassing situations, and we would love to hear any stories you have about using Safe Mode for troubleshooting.
