It doesn't work when task-manager is active window.
My Environment is:
Microsoft Windows [Version 10.0.18363.1379]

(Respectfully but in simple words) It is because task manager runs as administrator, and the tool (if not run as administrator) will be running as regular user and will have no power when task manager is in the foreground.

The goal can be achieved by running the tool as administrator, which can be done by configuring a Scheduled Task and have it run at startup and set it to run as administrator, or set the executable to always run as administrator.

I run this tool as administrator(right click -> run as administrator), but it still doesn't works.
