Hi Customer,
Welcome to Microsoft Community.
Based on the original description, we understand that your device is experiencing an unusual automatic reset of settings.
The system itself does not have the ability to change specific settings automatically and proactively.
This phenomenon may be related to certain “file states”, “computer states”. The settings item related to the taskbar revert to the state they were in at a particular point in time for unknown reasons.
Changes in power management policies, power status of the device may be one of the relevant factors, while corruption of the profile itself may be also an indirect factor.
If possible, would you mind sharing more information about this issue with us?
- Were there any special events in the device before the situation first occurred? For example, system update, driver update, application update, BIOS update, firmware update?
- Is the situation the same when you observe it in a relatively clean environment (for example, new local account, safe mode)? Manage user accounts in Windows - Microsoft Support
Windows startup settings - Microsoft Support
- Is the situation the same if you adjust options in your system that may be related to power management or file status? For example, fast startup, hibernation. Wake on LAN behavior - Windows Client | Microsoft Learn
How to disable and re-enable hibernation - Windows Client | Microsoft Learn
If I misunderstand your situation, feel free to correct me and share the information.
