Get classic old Task Manager in Windows 10

Many users are not happy with the new "modern" task manager which was introduced in Windows 8. Windows 10 comes with the same Task Manager app. Although some of its functions are not bad, like the performance graph, one might not really need them. The old Task Manager is faster, bug-free and provides a more reliable workflow of task management for me. It is familiar and the new one does not even remember the last active tab. So I am definitely one of those who want the good old, more usable Task Manager back in Windows 10. Here is how you can get it back without replacing any system files or modifying permissions.
