: Identifying bottlenecks in CPU, memory, and disk I/O.
While Windows includes native tools like Task Manager and Resource Monitor, Sysinternals offers significantly deeper insights. These tools provide granular data on process behavior, registry changes, and file system activity that standard administrative interfaces often obscure. They are widely used for: sysinternals

Often described as "Task Manager on steroids," Process Explorer shows you exactly which handles and DLLs processes have opened. It can pinpoint which program is "locking" a file you're trying to delete and provides real-time CPU usage for individual threads. 2.

Unlike most Sysinternals tools that are run on-demand, Sysmon is a system service that remains resident across reboots to log system activity to the Windows event log. It tracks process creations, network connections, and changes to file creation times, providing a rich audit trail for security analysts. 5. ProcDump
