如果您在尝试通过按CTRL+ALT+DEL或尝试Restart/Shut-down系统打开“安全和登录选项”窗口^{(Security and Sign-in Options)}时显示安全和关闭选项失败^{(Failure to display security and shut-down options)}，那么本文可能是对你有帮助。

无法显示安全和关闭选项

Windows 11/10上出现此问题的可能原因如下：

1. 系统文件损坏。
2. 某些第三方程序可能与该过程发生冲突。
3. 第三方安全软件正在阻止该过程。

错误可能伴随着声明——

The logon process was unable to display security and logon options when Ctrl+Alt+Delete was pressed. If Windows doesnt respond, press ESC or use the power switch to restart.

您可以尝试以下解决方案来解决问题：

1. 运行 SFC 和 DISM 扫描
2. 运行系统维护^{(System Maintenance)}疑难解答
3. ^{(Troubleshoot)}对处于干净启动状态的系统进行^{(Clean Boot State)}故障排除。

1]运行SFC和DISM扫描

问题的主要原因是系统文件损坏。在这种情况下，运行SFC和DISM扫描可能会有所帮助。这些工具可以帮助检测丢失和损坏的文件并替换它们。

系统文件检查器与Windows 资源保护^{(Windows Resource Protection)}集成，可保护注册表项和文件夹以及关键系统文件。如果检测到受保护的系统文件有任何更改，修改后的文件将从位于Windows文件夹本身的缓存副本中恢复。

如果SFC扫描没有帮助，您可以运行DISM 扫描^{(DISM scan)}。

2]运行^(Run)系统维护^{(System Maintenance)}疑难解答

系统^(System)维护疑难解答程序检查与系统相关的问题，并在可能的情况下对其进行疑难解答。运行系统维护疑难解答的过程如下：

Press Win+R打开“运行”^(Run)窗口并键入命令控制面板。按 Enter^{(Hit Enter)}打开“控制面板^{(Control Panel)}”窗口。将 View by 选项更改为小图标^{(Small icons)}（或大^(Large)图标，不应为Category）。

选择Troubleshooting > System and Security。从列表中选择系统维护^{(System Maintenance)}疑难解答并运行它。

完成后重新启动系统。

3]在干净启动状态^{(Clean Boot State)}下对系统进行故障排除^{(Troubleshoot)}

如果第三方软件干扰了进程，可以通过在干净启动状态下重新启动系统来隔离这种可能性。这样，您可以防止第三方软件在启动时启动。

如果在Clean Boot State中重新启动系统后问题得到解决，请尝试识别有问题的程序并将其卸载。

All the best!

Fix Failure to display security and shut-down options error in Windows

If you encounter a message – Failure to display security and shut-down options while trying to open the Security and Sign-in Options window by pressing CTRL+ALT+DEL or attempting to Restart/Shut-down the system, then this article may be helpful for you.

Failure to display security and shut-down options

The probable causes for this issue on Windows 11/10 are as follows:

1. Corruption of system files.
2. Some third-party programs might be conflicting with the process.
3. Third-Party security software is preventing the process.

The error may be accompanied by the statement-

The logon process was unable to display security and logon options when Ctrl+Alt+Delete was pressed. If Windows doesnt respond, press ESC or use the power switch to restart.

You may try the following solutions to fix the problems:

1. Run an SFC and DISM scan
2. Run the System Maintenance troubleshooter
3. Troubleshoot the system in the Clean Boot State.

1] Run an SFC and DISM scan

The main cause of the issue is corrupt system files. In this case, running SFC and DISM scans can be helpful. These tools can help in detecting missing and corrupt files and replace them.

The System File Checker is integrated with Windows Resource Protection, which protects registry keys and folders as well as critical system files. If any changes are detected to a protected system file, the modified file is restored from a cached copy located in the Windows folder itself.

If the SFC scan doesn’t help, you can run the DISM scan.

2] Run the System Maintenance troubleshooter

The System maintenance troubleshooter checks problems related to the system and troubleshoots them if possible. The procedure for running the System Maintenance Troubleshooter is as follows:

Press Win+R to open the Run window and type the command control panel. Hit Enter to open the Control Panel window. Change the View by option to Small icons (or Large icons, it shall not be Category).

Select Troubleshooting > System and Security. Choose the System Maintenance troubleshooter from the list and run it.

Restart the system once you are done.

3] Troubleshoot the system in the Clean Boot State

If third-party software is interfering with the processes, the possibility can be isolated by restarting the system in a clean boot state. This way, you could prevent third-party software from launching at the startup itself.

If the issue gets resolved after restarting the system in Clean Boot State, try identifying the troublesome program and uninstall it.

All the best!
