One of the things Microsoft updated in Windows 8 is Task Manager. It has a more user-friendly interface, provides more information, and is easier to use. If you want to get the features of the new Task Manager in Windows 7, check out DBC Task Manager.
DBC Task Manager has a similar UI as the Windows 8 Task Manager and some of its functionality. It doesn’t require installation, and won’t replace the existing Task Manager in Windows 7.
It doesn’t give you all of the features of the new Task Manager, but is a good start and offers something different for drilling down apps that are taking up system resources in Windows 7.
It’s currently a work in progress and you can download the 32 or 64-bit version of DBC Task Manager from Neowin.net.
