Understanding Processes: What to Keep and What to Terminate
As a general guide when reviewing the process list:
System processes to leave alone: System, System Idle Process, smss.exe, csrss.exe, wininit.exe, services.exe, lsass.exe, explorer.exe, svchost.exe. Terminating these will cause Windows to crash or become unstable.
Safe to terminate if not needed: Browser processes (chrome.exe, firefox.exe) if you have too many tabs open consuming RAM. Background updater processes (adobeupdateservice.exe, etc.). Media players or programs you're not actively using.
If unsure: Right-click and search Google for the process name before terminating. SterJo Task Manager makes this easy with its built-in search option.
