Windows Task Manager is a useful tool that allows you to manage processes and monitor system performance. Here are some basic steps to use Windows Task Manager:

1. To open Task Manager, right-click on the taskbar and select “Task Manager” or press the Ctrl + Shift + Esc keys.
2. By default, Task Manager opens in the “Processes” tab, which displays all the processes currently running on your system. You can sort the list by clicking on the column headers.
3. To end a process, select it and click on the “End task” button. Be careful when ending processes, as some are critical to the system and ending them may cause issues.
4. The “Performance” tab displays real-time information about your system’s CPU, memory, disk, and network usage. You can monitor the usage of each component and see which processes are using the most resources.
5. The “Startup” tab displays a list of programs that are set to run automatically when Windows starts up. You can disable programs that you don’t need to improve system performance.
6. The “Details” tab displays a more detailed view of the processes currently running on your system, including the process name, PID, CPU usage, and memory usage.
7. You can right-click on a process to perform additional actions, such as setting the priority, opening the file location, or searching online for information about the process.

Using Task Manager can help you identify and manage resource-intensive processes, monitor system performance, and optimize your system for better performance.
