Caps Lock键是(Caps Lock)Windows中为数不多的“切换”键之一，并且经常会卡在反向配置中，从而很难识别其实际状态。让我们看看如何解决这个问题。
这是与大写锁定卡住(Caps Lock)问题不同的问题，大写锁定(Caps Lock)按钮由于硬件或软件故障而持续按下。当大写锁定(Caps Lock)键反转时，启用大写锁定时您会得到小写字符，(Caps)而不是您期望的大写字符，反之亦然。
如果您不小心输入了大量文本而没有意识到此问题，您可以随时将其更改回 MS Word 中的句子大小写(change it back to sentence case in MS Word)，但这里有一些方法可以解决问题的根本原因。
1：检查Shift键
如果您按下Caps Lock并且指示灯熄灭，但您的按键仍然敲击大写字母，通常是因为您的Shift键被卡住了。它可能被物理卡住或者只是按下了内部开关（或橡胶圆顶）。
要验证这一点，您可以使用Windows 11(Windows 11)中的屏幕键盘。
- 在“开始”菜单(Start Menu)中键入“屏幕键盘”以找到该应用程序并启动它。
- 该应用程序会突出显示键盘上按下的按键。检查Shift(Shift)键是否在此处突出显示。
如果您的钥匙确实卡住了，您可以尝试点击它以使其释放。如果这不起作用并且您的钥匙仍然卡住，您可能需要撬开键帽。
当然，这只是一次性修复，以防钥匙出现故障。长期需要更换按键，这只有在热插拔机械键盘的情况下才有可能。对于普通的橡胶膜型号，必须更换整个键盘。
您还可以通过使用 AHK 或类似程序将功能映射到键盘上的其他键来(mapping the function to a different key on your keyboard with AHK or a similar program)解决损坏的 Shift 或Windows键。这可以让您继续使用键盘一段时间。
2：重新连接键盘
即使Caps Lock或Shift键没有被物理卡住，键盘也可能被卡住并发送了错误的信号。最简单的解决方法是尝试重新连接键盘。
从PC 的USB端口拔下设备。对于无线键盘，这意味着拔出小型无线集线器。然后再次插回，让Windows重新启动相关服务。
这将修复键盘的任何连接或配置问题，并让您再次正常
使用大写锁定键。(Caps)
3：运行键盘疑难解答(Keyboard Troubleshooter)
内置的Windows疑难解答程序通常不足以捕获除最微小问题之外的任何问题，但首先尝试它们仍然是一个好主意。对于任何键盘问题，这意味着运行键盘(Keyboard)疑难解答。
但有一个小问题 -微软(Microsoft)正在弃用旧版疑难解答程序，包括键盘疑难解答程序。虽然该过程尚未完成，但重新设计的疑难解答(Troubleshooter)设置不再包含键盘(Keyboard)疑难解答。
幸运的是，您仍然可以直接在“开始”(Start)菜单中搜索“键盘(Keyboard)疑难解答”并尝试该应用程序。
4：关闭过滤器键
Microsoft Windows具有许多辅助功能，例如粘滞键(Sticky keys)和过滤键(Filter keys)，使残障人士可以更轻松地控制他们的电脑。但是，如果在您不需要这些功能时启用它们，则可能会产生问题
例如， Filter Keys(Filter Keys)旨在忽略重复的键并自定义重复率。当您无法快速敲击按键时，这非常有用，因为它可以让您忽略按键，直到按下按键为止。
但是，当它在正常使用过程中被激活时，即使硬件没有故障，它也会使某些按键看起来死机或无响应。
- 要关闭过滤键，请打开“设置”(Settings)。只需(Just)单击“开始”(Start)菜单中的齿轮图标即可。
- 找到左侧的“辅助功能”部分并切换到它。(Accessibility)向下滚动(Scroll)窗口，直到找到“交互”(Interaction)标题，在该标题下您将找到“键盘”(Keyboard)选项。
- 选择此选项将为您带来所有与键盘相关的辅助功能选项，包括过滤器(Filter)键。只需(Simply)单击开关即可停用该功能。
请记住，相比之下，打开过滤器键要容易得多，因为您所需要做的就是按住右侧Shift键 8 秒或更长时间。这就是为什么当您不需要
过滤器(Filter)键时很容易意外启用它。
5：重新安装键盘驱动程序
由于Microsoft Windows会自动安装键盘驱动程序，因此用户无需手动安装。但是，当您的键盘无法正常工作时，强制重新安装驱动程序可能是个好主意。
我们可以通过从设备管理器(Device Manager)卸载键盘来轻松完成此操作，并在您重新启动电脑时提示 Windows 重新安装丢失的驱动程序。这基本上是一种将键盘重置为其默认设置(resetting your keyboard to its default settings)的方法。
- 要重新安装键盘驱动程序，请首先在“开始”(Start)菜单中搜索“设备管理器”(Device Manager)并将其打开。
- 该窗口列出了电脑的所有硬件，包括键盘等外围设备。单击(Click)键盘旁边的小箭头以展开该部分。
- 现在您将获得插入 PC 的实际键盘的列表。例如，如果您有一个连接到笔记本电脑的USB键盘，它将显示两个键盘 - 一个是集成键盘 ( (USB)HID )，另一个是可移动键盘 (Standard PS/2 )。右键单击给您带来麻烦的键盘，然后选择卸载设备(Uninstall Device)。
- 系统将提示您确认您的决定。单击(Click)“卸载”(Uninstall)按钮继续。
Windows将卸载键盘，使其无法使用。不要惊慌 – 只需重新启动您的电脑即可再次恢复驱动程序，因为Windows会在您启动计算机时检查丢失的驱动程序并重新安装它们。
修复Windows(Windows)中的反向大写锁定问题的(Caps Lock Issue)最佳方法(Best Method)是什么？
一般来说，反向大写锁定在(Caps Lock)Windows中并不是一个主要问题。通常是配置问题或临时错误，可以通过拔下键盘甚至重新安装其驱动程序来修复。
某些(Certain)设置（例如过滤(Filter)键）可能会使键盘脱离其正常行为，使大写锁定(Caps Lock)看起来不起作用。键盘故障排除程序通常可以找出这些隐藏的配置问题。
如果这些都不起作用，则表明您设备的实际按键存在问题。Shift键可能被卡住，或者完全损坏，通常需要更换才能修复。(Shift)有进取心的用户可以通过使用AHK将其功能重新映射到不同的键来创建解决方法。
How to Fix Reversed Caps Lock Issue in Windows
The Cаps Lock key is one of the few “toggle” keys in Windows, and can often get stuck in a reverse configuratiоn, making it tricky to reсognize its aсtual statе. Let’s look at how to fix this issue.
This is a distinct problem from the stuck Caps Lock issue, where the Caps Lock button remains continuously pressed due to a hardware or software fault. When your Caps Lock key is reversed, you get lower case characters when Caps lock is enabled, instead of uppercase as you would expect, and vice versa.
If you have accidentally typed a lot of text without realizing this problem, you can always change it back to sentence case in MS Word, but here are some ways to fix the root cause of the problem.
1: Check the Shift Key
If you press your Caps Lock and the indicator goes off but your keys still hit capital letters, it’s usually because your Shift key is stuck. It could be physically jammed or just have the internal switch (or rubber dome) depressed.
To verify this, you can use the on-screen keyboard in Windows 11.
- Type “On-Screen Keyboard” in the Start Menu to find the app and launch it.
- The application highlights keys pressed on your keyboard. Check whether the Shift key shows up highlighted here.
If your key is indeed stuck, you can try tapping it to get it to release. In case that doesn’t work and your key remains stuck, you may have to pry off the keycap.
This is only a one-time fix, of course, in case the key is malfunctioning. Long term you need to replace the key, which is only possible in the case of a hot-swappable mechanical keyboard. For a normal rubber membrane model, the entire keyboard has to be replaced.
You can also work around a broken Shift or Windows key by mapping the function to a different key on your keyboard with AHK or a similar program. This lets you keep using the keyboard for a while longer.
2: Reconnect Your Keyboard
Even if the Caps Lock or the Shift key is not physically stuck, it is possible that the keyboard is stuck sending the wrong signal. The simplest fix for this is to just try reconnecting your keyboard.
Unplug the device from the USB port of your PC. For a wireless keyboard, this means pulling out the small wireless hub. Then plug it back in again, letting Windows restart the relevant service.
This will fix any connection or configuration issues with the keyboard and let you use the Caps lock key normally again.
3: Run the Keyboard Troubleshooter
The built-in Windows troubleshooters usually aren’t good enough to catch anything but the most minor problems, but it’s still a good idea to try them out first. For any keyboard issue, this means running the Keyboard troubleshooter.
There is a small problem though – Microsoft is in the process of deprecating the legacy troubleshooters, including the keyboard troubleshooter. While the process hasn’t been completed yet, the reworked Troubleshooter settings no longer have a Keyboard troubleshooter.
Luckily, you can still directly search for the Keyboard troubleshooter in the Start menu and try the application.
4: Turn Off Filter Keys
Microsoft Windows has many accessibility features like Sticky keys and Filter keys to make it easier for people with disabilities to control their PCs. But these same features can create issues if they get enabled when you don’t need them
Filter Keys, for example, is designed to ignore repeated keys and customize the repeat rate. This can be very useful when you have trouble quickly tapping keys, as it lets you ignore keypresses until they are held down.
But when it gets activated during normal usage, it can make certain keys seem dead or unresponsive, even though the hardware is not at fault.
- To turn off filter keys, open Settings. Just click on the gear icon in the Start menu.
- Find the Accessibility section on the left and switch to it. Scroll down the window until you find the Interaction header, under which you will find the Keyboard option.
- Selecting this brings you to all the keyboard-related accessibility options, including Filter keys. Simply click on the toggle to deactivate the feature.
Keep in mind that turning on the filter keys is much easier by comparison since all you need to do is hold the right Shift key for 8 seconds or more. This is why it is very easy to accidentally enable Filter keys when you don’t need it.
5: Reinstall Keyboard Drivers
Since Microsoft Windows installs keyboard drivers automatically, there’s no need for a user to do it manually. But when your keyboard is not functioning properly, it can be a good idea to force the drivers to reinstall.
We can do this easily by uninstalling the keyboard from the Device Manager, prompting Windows to reinstall the missing drivers when you restart your PC. This is basically a way of resetting your keyboard to its default settings.
- To reinstall your keyboard drivers, first search for the Device Manager in the Start menu and open it.
- The window lists all the hardware that comprises your PC, including peripherals like keyboards. Click on the small arrow next to Keyboards to expand the section.
- Now you will get a list of the actual keyboards plugged into your PC. If you have a USB keyboard connected to a laptop, for example, it will show two keyboards – one integrated (HID), the other removable (Standard PS/2). Right-click on the keyboard giving you trouble and select Uninstall Device.
- You will be prompted to confirm your decision. Click on the Uninstall button to proceed.
Windows will uninstall the keyboard, making it unusable. Don’t panic – just restart your PC to get the drivers back again, as Windows checks for missing drivers and reinstalls them when you boot up the computer.
What Is the Best Method of Fixing the Reversed Caps Lock Issue in Windows?
Generally speaking, a reversed Caps Lock is not a major issue in Windows. Usually a configuration problem or a temporary bug, it can be fixed by unplugging your keyboard or even reinstalling its drivers.
Certain settings like Filter keys can throw off your keyboard from its normal behavior making the Caps Lock seem non-functional. The keyboard troubleshooter can often dig out these hidden configuration issues.
If none of these work, it points to a problem with the actual keys of your device. The Shift key might be stuck, or just outright broken, which usually needs replacement to fix. Enterprising users can create workarounds by using AHK to remap its function to a different key.
