Windows键位于键盘的左下角，是您通往Windows操作系统的门户。它会打开您的“开始(Start)”菜单，让您可以轻松访问重要的应用程序和文件，但它也可以用作其他快速访问键盘快捷键的(quick-access keyboard shortcuts)一部分，以节省时间并提高工作效率。
当您的Windows键盘按键中断时，您将失去最基本的工具之一。除非您想忘记一些最基本的 Windows 技能(basic Windows skills)，否则您需要修复损坏的键盘键。有几种方法可以做到这一点，所以为了帮助您，您可以遵循以下几个步骤。
检查键盘是否损坏(Check Your Keyboard For Damage)
在你做任何其他事情之前，你应该检查你的键盘是否有物理损坏。首先看一下Windows键本身——它是否像其他键一样有弹性，或者感觉下面可能有灰尘或碎屑？如果有，请尝试清洁它。
您可能可以移除密钥本身来执行此操作，但在尝试此操作之前请先查看您的手册，以确保您可以在不损坏密钥本身的情况下这样做。
您还应该将您的键盘视为一个整体。例如，有线键盘上损坏的电线可能足以阻止部分或全部按键工作。您的设备也可能存在无法通过目视检查检测到的问题。
如果键盘上的其他键也不再起作用，这很可能是真的。如果你把饮料洒在你的按键(spilled a drink over your keys)上，这足以打破你的键盘。如果是这种情况，请检查您的设备保修或寻求第三方维修。
尝试替代键盘(Try An Alternative Keyboard)
如果您确信您的键盘没有（或不应该）损坏，那么您需要测试该理论。执行此操作的一个好方法是使用替代键盘来测试该设备上的Windows键。
此测试可让您查看Windows本身是否存在问题。如果软件问题导致Windows密钥停止响应（例如，由于文件损坏或恶意软件感染(malware infection)），则Windows密钥不应在任一设备上工作。
但是，如果备用键盘确实有效，那么您可能可以排除软件问题。在您这样做之前，请研究您的键盘型号并确定是否有其他人报告的其他问题可以帮助您缩小问题范围。
检查 Windows 系统和文件完整性(Check Windows System And File Integrity)
当Windows处于完美的工作状态时，您不必担心按键损坏。但是，当它不起作用时，任何数量的丢失文件或丢失的进程都可能会阻止最基本的功能（例如Windows键盘键）正常工作。
测试是否是这种情况的一个好方法是使用Windows PowerShell检查您的(Windows PowerShell)Windows系统和文件完整性。您可以使用系统文件检查器 (sfc) 工具(System File Checker (sfc) tool )快速修复损坏的 Windows 文件(repair corrupt Windows files)。
- 为此，请右键单击开始(Start)菜单，然后单击Windows PowerShell (Admin)。在PowerShell终端窗口中，键入sfc /scannow开始检查您的系统。
系统文件检查器(System File Checker)工具完成扫描后，您可以运行检查磁盘工具 (chkdsk)(Check Disk tool (chkdsk))(Check Disk tool (chkdsk))来检查和修复Windows文件系统错误。
- 在打开的PowerShell窗口中，键入chkdsk /r 开始扫描。Windows 无法在启动时运行此扫描，因此您需要批准启动扫描以在您下次重新启动 PC 时检查您的系统。键入Y以批准此操作，然后手动重新启动以开始扫描。
一旦您的 PC 重新启动，扫描就会开始。任何可能影响Windows执行方式的驱动器问题都应自动修复。
禁用 Windows 筛选键(Disable Windows Filter Keys)
Windows 10(Windows 10 accessibility features)更有用的辅助功能之一是能够为可能意外按键的用户过滤掉不必要的击键。不幸的是，对于那些不需要它的人来说，这个功能可能会被意外启用，导致Windows忽略Windows键本身的按下。
您可以在Windows 设置(Windows Settings)菜单的键盘(Keyboards )区域中禁用此过滤键功能。
- 要访问您的设置，请右键单击“开始(Start)”菜单，然后单击“设置”(Settings)。在此处，按Ease of Access > Keyboard以访问您的Windows键盘设置。
- 在键盘(Keyboards)菜单中，找到使用过滤键(Use Filter Keys)设置。单击(Click)此设置的切换开关以禁用它，确保显示关闭(Off)标签。
检查无线键盘上的电池电量(Check Battery Levels On Wireless Keyboards)
如果您使用的是无线键盘，那么您应该已经定期为其充电。如果您的键盘按键在无线键盘上停止工作(keyboard keys stop working)，那么您可能需要检查它是否有足够的电池电量来注册正确的按键操作。
如何检查会有所不同，具体取决于您拥有的设备。某些无线键盘可能在产品本身上有电池指示灯，或者您可能需要制造商提供的第三方应用程序来检查设备是否充满电。
如果您无法检查这一点，请让设备充电几个小时，然后再次使用键盘。这应该留出足够的时间让键盘有足够的电量开始工作，除非电池或产品本身存在问题，需要制造商的额外支持才能进行故障排除或维修。
使用第三方软件切换 Windows 键(Use Third Party Software To Switch The Windows Key)
如果这些方法不能修复Windows中损坏的键盘键，您可能需要考虑更换键盘。但是，在您这样做之前，您可以使用第三方软件将损坏的Windows键换成另一个工作键。
您可能会发现设备上的其他键未使用，例如右Ctrl键。您可以使用SharpKeys重新映射此键(remap this key)，该实用程序旨在让您快速将一个键切换到另一个键。
- 安装SharpKeys 后，您可以通过单击(SharpKeys)添加(Add )按钮将一个键映射到另一个键。
- 您需要使用左侧菜单将Windows键（Special: Left Windows (E0_5B)或Special: Right Windows (E0_5C) ）映射到右侧列出的物理键。(Special: Right Windows (E0_5C))在此处选择您的键，然后单击确定(OK)将其保存到SharpKeys键映射列表。
- 重新映射 Windows 键后，按写入注册表(Write to Registry)以保存更改。之后您可能需要重新启动设备。
修复 Windows 键盘问题(Fixing Windows Keyboard Issues)
Windows中损坏的键盘键可能难以处理，但您应该能够使用上面列出的方法之一解决问题。首先，检查电池电量和物理检查键盘可以解决问题，但也不要忘记拔下电源插头并重新插入以重新注册您的设备。
一旦您的键盘正常工作(keyboard is working)，您就可以开始按照设计的方式使用Windows 。许多(Many)适用于Windows 10的最有用的键盘快捷键(useful keyboard shortcuts)都使用Windows键，包括快速截取屏幕截图(quickly take screenshots)并将其保存到文件的能力。在下面的评论中让我们知道您的Windows键盘提示。
How To Fix a Broken Windows Keyboard Key
The Windowѕ key, situated in the bottom-left of your keyboard, is your gateway to the Windows operating systеm. It brings up your Start mеnu, giving you easy access to уour important apрs and files, but it can also be υsed as part of other quick-access keyboard shortcuts to save time and improve productivity.
When your Windows keyboard key breaks, you’re left without one of your most basic tools. Unless you want to unlearn some of the most basic Windows skills, you’ll need to fix your broken keyboard key instead. There are a few ways to do this, so to help you, here are a few steps you can follow.
Check Your Keyboard For Damage
Before you do anything else, you should inspect your keyboard for physical damage. Start by looking at the Windows key itself—does it feels as springy as the other keys, or does it feel like there might be dirt or debris stuck underneath? If there is, try to clean it.
You may be able to remove the key itself to do this, but check your manual first before you try this to make sure you can without damaging the key itself.
You should also look at your keyboard as a whole. A damaged wire on a wired keyboard, for instance, could be enough to stop some or all keys from working. There may also be undetectable issues with your device that you simply can’t detect from a visual inspection.
This will likely be true if other keys on your keyboard are no longer working, too. If you’ve spilled a drink over your keys, this would be enough to break your keyboard. Check your device warranty or seek third-party repairs if this is the case.
Try An Alternative Keyboard
If you’re confident that your keyboard isn’t (or shouldn’t) be damaged, then you’ll need to test the theory. A good way to do this is to use an alternative keyboard to test the Windows key on that device.
This test allows you to see if Windows itself is the problem. If a software issue is causing the Windows key to stop responding (for instance, due to corrupt files or a malware infection), then the Windows key shouldn’t work on either device.
If the alternative keyboard does work, however, then you can probably rule out a software issue as the problem. Before you do, research your keyboard model and determine if there are any other issues that others have reported that could help you narrow down the problem.
Check Windows System And File Integrity
When Windows is in perfect working order, you shouldn’t need to worry about broken keys. When it isn’t working, however, any number of missing files or missing processes could stop the most basic features—such as your Windows keyboard key—from working correctly.
A good way to test if this is the case is to check your Windows system and file integrity using the Windows PowerShell. You can use the System File Checker (sfc) tool to quickly repair corrupt Windows files.
- To do this, right-click the Start menu and click Windows PowerShell (Admin). In the PowerShell terminal window, type sfc /scannow to begin checking your system.
Once the System File Checker tool has completed your scan, you can run the Check Disk tool (chkdsk) to check for and repair Windows file system errors.
- In the open PowerShell window, type chkdsk /r to begin the scan. Windows can’t run this scan while booted up, so you’ll need to approve a boot scan to check your system when you next restart your PC. Type Y to approve this, then manually reboot to begin the scan.
Once your PC restarts, the scan should begin. Any problems with your drive that could impact on how Windows is performing should be repaired automatically.
Disable Windows Filter Keys
One of the more useful Windows 10 accessibility features is the ability to filter out unnecessary keystrokes for users who may press keys by accident. Unfortunately, this feature can be enabled by accident for those who don’t need it, causing Windows to ignore presses of the Windows key itself.
You can disable this filter keys feature in the Keyboards area of the Windows Settings menu.
- To access your settings, right-click the Start menu and click Settings. From here, press Ease of Access > Keyboard to access your Windows keyboard settings.
- In the Keyboards menu, find the Use Filter Keys setting. Click the toggle for this setting to disable it, ensuring that the Off label is displayed.
Check Battery Levels On Wireless Keyboards
If you’re using a wireless keyboard, then you should already be in a regular schedule of keeping it charged. If your keyboard keys stop working on a wireless keyboard, then you may want to check whether it has enough battery charge to register the correct key presses.
How to check this will vary, depending on the device you own. Some wireless keyboards may have battery indicators on the product itself, or you may need third-party apps from the manufacturer to check whether the device is sufficiently charged.
If you can’t check this, then leave the device to charge for a few hours before using the keyboard again. This should leave enough time for the keyboard to have sufficient charge to begin working, unless there’s an issue with the battery or product itself that requires additional support from the manufacturer to troubleshoot or repair.
Use Third Party Software To Switch The Windows Key
If these methods don’t fix a broken keyboard key in Windows, you may need to consider replacing your keyboard. Before you do that, however, you could use third-party software to switch the broken Windows key with another, working key instead.
You may find other keys on your device aren’t being used, such as the right Ctrl key. You could remap this key using SharpKeys, a utility designed to quickly allow you to switch one key for another.
- Once you’ve installed SharpKeys, you can map one key to another by clicking the Add button.
- You’ll need to map the Windows key (Special: Left Windows (E0_5B) or Special: Right Windows (E0_5C)) using the left-hand menu to a physical key listed on the right. Select your keys here, then click OK to save it to the SharpKeys key mapping list.
- Once you’ve re-mapped your Windows key, press Write to Registry to save the changes. You may need to restart your device afterwards.
Fixing Windows Keyboard Issues
A broken keyboard key in Windows can be difficult to deal with, but you should be able to resolve the problem using one of the methods listed above. In the first instance, checking battery levels and physically inspecting your keyboard could solve the problem, but don’t forget to unplug and plug it back in to re-register your device, too.
Once your keyboard is working, you can start to use Windows the way it was designed. Many of the most useful keyboard shortcuts for Windows 10 use the Windows key, including the ability to quickly take screenshots and save them to a file.
