NTop

Regardless of whether it is an unresponsive window, high CPU usage, freezing or perhaps a suspicious app, the first instinct is to open Task Manager to figure out what is happening. While it is an overall decent option, Task Manager is still lacking in terms of features and options.
NTop is a console-based Task Manager alternative that offers a few extra options compared to the Windows embedded tool. For starters, the program comes with Vi emulation and hence, allows users to make searches, sort processes list after a given column, view process tree, kill processes or execute commands.
Navigating through the processes can be done via the up and down arrow keys, whereas browsing through the columns entails holding Control and using the left and right arrow keys. The app enables the tagging and following of various processes as well as killing the suspicious or unresponsive ones.
The information about the usage statistics of the PC are displayed in the upper section with clear details. For example, users can preview the total available RAM and CPU along with details such as the percentage of memory being used or the number of tasks running. The app shows the total available RAM and tasks, so users can make estimations easier.
