windows11回退windows10后无法打开开始菜单和设置

您好 fan rui meng，

感谢您联系 Microsoft Q&A。

为了更好地了解该问题，并确认是否与 Windows 回退过程有关，请协助收集以下信息：

1. 开始菜单相关进程是否正在运行？

请打开 PowerShell 并执行以下命令：

• Get-Process -Name ShellExperienceHost
• Get-Process -Name SearchUI

请将执行结果分享给我们。

2. 该系统是从 Windows 10 升级到 Windows 11 后再回退到 Windows 10，还是直接全新安装的 Windows 10？

请在 PowerShell 中执行以下命令：

• Test-Path "$env:windir\Panther\miglog.xml"

如果返回结果为 True，则表示该系统曾执行过升级。

如果返回结果为 False（文件不存在），则更可能是全新安装的系统。

3. 测试是否能够手动启动 Windows Explorer

请按照以下步骤操作：

• 按 Windows + R 打开“运行”窗口。
• 输入：explorer.exe
• 点击“确定”，并告知我们 Windows Explorer 是否能够正常打开，或者是否出现任何错误信息。

此外，烦请告知您当前使用的 Windows 10 版本 是什么？

您可以按 Windows + R，输入 winver，然后将显示的版本信息（例如 Windows 10 22H2、21H2 等）截图或发送给我们，以便进一步分析问题。

与此同时，请先尝试以下故障排除步骤：

1. 重启 Windows Explorer
2. 按 Ctrl + Shift + Esc 打开任务管理器。
3. 找到 Windows Explorer（Windows 资源管理器）。
4. 右键单击并选择 重新启动（Restart）。
5. 运行系统文件修复

请以管理员身份打开命令提示符（Command Prompt），执行以下命令：

• sfc /scannow

待其执行完成后，再运行：

• DISM /Online /Cleanup-Image /RestoreHealth

如果完成上述步骤后问题仍然存在，请收集以下日志用于进一步分析，并将日志上传到 OneDrive 后与我们共享下载链接：

• System Event Log（系统事件日志）
• Application Event Log（应用程序事件日志）
• Microsoft-Windows-Shell-Core*
• Microsoft-Windows-Apps/*
• Microsoft-Windows-TWinUI*

收到上述信息和日志后，我们将继续进行调查，并提供进一步的建议。

感谢您的配合。

希望以上信息能够为您提供帮助。如有任何疑问或需要进一步协助，请随时联系我们。

如果本回复解决了您的问题，也欢迎您将其标记为答案。

此致

Dear fan rui meng,

Thank you for contacting Microsoft Q&A.

To better understand the issue and determine whether this is related to the Windows rollback process, could you please help us collect the following information?

1. Is the Start Menu process running?

Please open PowerShell and run:

• Get-Process -Name ShellExperienceHost
• Get-Process -Name SearchUI

Kindly share the results with us.

2. Was this system originally upgraded from Windows 10 to Windows 11 and then rolled back to Windows 10, or was Windows 10 installed as a clean installation?

Please run the following command in PowerShell:

• Test-Path "$env:windir\Panther\miglog.xml"

If the result is True, the system was upgraded.

If the file does not exist (False), it is more likely a clean installation.

3. Test whether Windows Explorer can be launched manually

• Press Windows + R to open the Run dialog.
• Type: explorer.exe
• Click OK and let us know whether Windows Explorer opens successfully or if any error message is displayed.

Additionally, could you please let us know which version of Windows 10 you are currently using?

You can press Windows + R, type winver, and then share a screenshot of the version information (for example, Windows 10 22H2, 21H2, etc.) with us. This will help us further investigate the issue.

In the meantime, please try the following troubleshooting steps:

1. Restart Windows Explorer

• Press Ctrl + Shift + Esc to open Task Manager.
• Locate Windows Explorer.
• Right-click it and select Restart.

2. Run System File Repair

Open Command Prompt as Administrator and run:

• sfc /scannow

After it completes, run:

• DISM /Online /Cleanup-Image /RestoreHealth

If the issue persists after performing the above steps, please collect and provide the following logs for further investigation, then upload to OneDrive and kindly share link with us:

• System Event Log
• Application Event Log
• Microsoft-Windows-Shell-Core*
• Microsoft-Windows-Apps/*
• Microsoft-Windows-TWinUI*

Once we receive the requested information and logs, we will continue our investigation and provide further guidance.

Thank you for your cooperation.

Hope you found something helpful here. Please let me know if you need further assistance.

If this answer could solve the issue, it's appreciated to accept the answer.
