How to turn off remote control on Lenovo laptops is as follows:

1. Open computer properties, select remote settings, open the remote settings window and cancel "Allow remote connections to this computer", so that you can turn off remote control. Keep the computer in a relatively safe state.

2. You can also remove "Allow this computer to be remotely controlled" in the advanced options and set the time for remote control.

Note: If you want to allow remote control, you only need to follow this step and reverse the settings.
