SysTracer is a system utility tool designed to scan and analyze your computer for any changes made to the registry and files. It offers a comprehensive scan of your system, recording information about various aspects such as modified files and folders, registry entries, installed programs, system services, system drivers, applications set to run at startup, running processes, loaded DLLs, and opened files, folders, and registry.

On Unix and Linux systems, we can use the "tail -f" command to view and monitor the information in the log files generated by the system or software. This is a very useful feature for programmers or system administrators. It's a pity that Windows doesn't have this feature built in. If you need to implement similar functions, you can use a third-party program, Tail4win.
