Final answer:
Yes, Tablet mode can be enabled every time Windows 10 restarts, even with an attached keyboard, by adjusting the settings in 'Tablet mode' under System Settings.
Step-by-step explanation:
The ability to enable Tablet mode every time Windows 10 restarts, even with an attached keyboard, is a feature provided in the operating system's settings. To ensure that Tablet mode is automatically activated on startup, you can adjust the appropriate setting in the System Settings under 'Tablet mode'. As of the knowledge cutoff date in 2023, users can choose the mode that Windows 10 boots into regardless of whether an external keyboard is connected or not.
To do this, go to Settings, then System, and select 'Tablet mode'. Here you can choose the option 'Use Tablet mode' and set it to 'On' to ensure Tablet mode is enabled at every startup. If you set it to "Use the appropriate mode for my hardware", Windows will decide whether to enable Tablet mode based on the presence of a keyboard. However, selecting the 'On' option overrides this automatic detection, forcing Tablet mode each time.
