Can this program control LOCALSYSTEM processes like Windows Update? I've often seen windows update hog 100% CPU usage under the process svchost.exe. Windows's own task manager won't change its priority since it is LOCALSYSTEM, but will this program be able to do so?
In my experience, most lightweight memory tools focus on user-level processes and don't usually interfere with critical SYSTEM services like Windows Update. Trying to optimize those can risk stability, so it's better to target background apps and non-essential services for smoother performance without causing issues.
