In their own words

Process Lasso

Process Lasso is Windows software for automating process controls and helping maintain system responsiveness. Its ProBalance feature adjusts running programs’ priorities during high CPU loads. Persistent settings can apply CPU affinities, CPU sets, and priorities when processes launch, while rules can automate those controls, power profiles, and other actions based on thresholds or other criteria. Power plan automation can respond to selected processes or system idle time; Keep Awake can prevent sleep for a chosen period or while selected processes run. Listed algorithms include CPU Limiter, Instance Balancer, and Group Extender, and the software can log process launches and other selected system activity. A separate background service, Process Governor, enforces algorithms and rules; the graphical interface is optional. The free plan can be used indefinitely by most users, but some features are trial-only and commercial use requires purchase within 30 days of deployment. Single PC Monthly is listed at $4.95 a month as a recurring subscription. Compatibility is listed for Windows 7–11 and Windows Server 2012–2025.
