Surface Pro 6，24H2，平板模式优化部分失效

Question

简单来说就是现在拔掉键盘只有任务栏会变成平板模式的任务栏，别的什么东西都和桌面模式一样不会像以前自动变了，请告诉我怎么解决，谢谢。

下面是在ms 社区英文区写的详细的求助，实在没力气用中文再写一遍了抱歉。

I use the Surface Pro 6,I can't get into the tablet mode when the keyboard unplugged. When I unplugged the keyboard, the situation:

•"Optimise taskbar for touch interactions when this device is used as a tablet" and touch keyboard Worked well.

•Microsoft Edge is NOT in touch mode (tabs, bookmarks, buttons etc.) are also NOT optimised for touch when Touch mode is set to Auto (default), which should only be enabled "when Microsoft Edge recognises you're using your device as a tablet," according to the settings.

•The bottoms in the context menu and the Start menu are NOT get bigger than normal PC mode.

I already did:

•Installed again the last version of windows 11 for twice by using offical ISO file.

•Registry Editor: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ImmersiveShell -> TabletMode set to 1

•Reinstall the official driver pack for Surface Pro 6

But the problem still exists.
