如果在更新 Windows 11/10并在登录时，系统提示您输入一个您显然从未在设备上设置过的PIN ，您可以尝试这篇文章中提供的解决方案来解决这个看似奇怪的问题。^(PIN)

Windows 在登录^(Sign-in)屏幕上要求输入 PIN^(PIN)而不是密码

如果您遇到此问题，您可以尝试以下我们推荐的解决方案（不分先后顺序），看看是否有助于解决问题。

1. 添加然后删除 PIN
2. 卸载 Windows 更新
3. 执行系统还原
4. 重置 Windows 11/10

让我们看一下关于列出的每个解决方案所涉及的过程的描述。

在您尝试以下解决方案之前，如果您看到如上图所示的PIN登录提示，您可以单击其他登录选项（^(PIN)钥匙^(Key)图标），看看您是否可以输入密码并成功登录. 您也可以尝试添加然后删除 PIN 码^{(add and then remove the PIN)}。如果这有帮助，那么请继续使用以下解决方案。

1]卸载Windows更新

通常不建议卸载更新。但在这种情况下，您可能必须卸载^{(uninstall the ‘buggy’ update)}Windows 10 设备上的“错误”更新。

如果卸载更新后问题仍未解决，请尝试下一个解决方案。

2]执行系统还原

由于您无法登录Windows设备并进入桌面，因此您可以在无法启动到桌面时执行系统还原方法^{(System Restore method when you can’t boot to the desktop)}。

此系统还原^{(System Restore)}操作会将您的系统恢复到当前导致问题的更新安装之前的早期状态。

之后，您可以隐藏该更新^{(Hide that update)}或暂停更新^{(Pause Updates)}7 天——这让Microsoft有时间发布更新的修复程序。

3]重置Windows 10

同样，由于您无法访问 Windows 10 设备上的桌面执行重置，您可以尝试高级选项中的重置方法^{(Reset method from Advanced Options)}。就是这样：

• 关闭并启动计算机。
• 按 F11 进入 Windows高级启动选项^{(Advanced Startup Options)} 菜单。
• 选择 疑难解答^{(Troubleshoot)}。​​​
• 选择重置这台电脑^{(Reset this PC)}。​​​
• 选择保留我的文件^{(Keep my files )}选项..
• 按照屏幕上的说明进行操作。​

确保^(Make)让 Windows 10 保存现有文件和数据。

希望这可以帮助！

Windows asks for PIN instead of password on Sign-in screen

If you’re faced with this issue, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue.

1. Add and then remove the PIN
2. Uninstall the Windows Update
3. Perform System Restore
4. Reset Windows 11/10

Let’s take a look at the description of the process involved concerning each of the listed solutions.

Before you try the solutions below, if you are presented with the PIN login prompt as shown in the lead-in image above, you can click other Sign-in options (the Key icon) and see if you can input your password and login successfully. You may also try to add and then remove the PIN. If that helps, good else proceed with the solutions below.

1] Uninstall the Windows Update

Uninstalling updates is usually not recommended. But in cases like this, you might have to uninstall the ‘buggy’ update on your Windows 10 device.

If after uninstalling the update but the issue isn’t resolved, try the next solution.

2] Perform System Restore

As you’re unable to log into your Windows device and get to the desktop, you can perform the System Restore method when you can’t boot to the desktop.

This System Restore operation reverts your system back to an earlier state before the update installation that is causing issues at the moment.

After that, you may Hide that update or Pause Updates for say 7 days – which gives time for Microsoft to release an updated fix.

3] Reset Windows 10

Here again, as you can’t get to the desktop on your Windows 10 device to perform a reset, you can try the Reset method from Advanced Options. Here’s how:

• Turn off and start the computer​.
• Press F11 to enter the Windows Advanced Startup Options menu.
• Select Troubleshoot. ​
• Select Reset this PC. ​
• Select Keep my files ​option.. ​
• Follow the on-screen instructions.​

Make sure you make Windows 10 save your existing files and data.

Hope this helps!
