Windows 10 comes with a Task Manager which is similar to Windows 8 and radically different from the one in Windows 7 and earlier. It has some nice features, like the performance graph or startup impact calculation. It is able to control which apps launch during startup and can analyze performance of various hardware components. However, only the Processes tab shows if a process is 32-bit. So you might want to tweak the Details tab to show this information too.
