Hi FF_629,
Welcome to Microsoft Community.
Windows itself does not integrate the ability to trigger shutdown/restart behavior by keys other than the power button.
This phenomenon may be influenced by certain programs or services.
Would you mind sharing more information about this issue with us?
- Does pressing the corresponding key with the On-Screen Keyboard trigger the same behavior? Use the On-Screen Keyboard (OSK) to type - Microsoft Support
.
- Will the situation remain the same when performing the test in safe mode? Start your PC in safe mode in Windows - Microsoft Support
- Will you get the same results when running the test under a new local account? Create a local user or administrator account in Windows - Microsoft Support
- Is the problem a recent phenomenon? Or has it existed for a long time?
- Were there any special events in the device before the problem occurs? For example, system update, driver update, application update, BIOS update?
If I misunderstand your situation, feel free to correct me and share the information.
