Process Lasso and Never Spin solve different versions of “my PC is slow.”

Choose by control level

Never Spin is an alternative only when you want less configuration.

These products are not clones. Process Lasso is a mature Windows utility with tools for persistent process priority, CPU affinity, CPU sets, power profiles, and broader automation. That depth is useful to enthusiasts, gamers, workstation operators, and administrators who know which process behavior they want to control.

Choose Process Lasso when

• You need persistent priority or affinity rules for named processes.
• You want CPU sets, power-profile automation, or detailed process tuning.
• You are comfortable testing rules and understanding their side effects.
• Your computers are Windows-based.

Choose Never Spin when

• You want a smaller, simpler automatic response to sustained background CPU or memory load.
• You want the three most recently used apps protected automatically.
• You want whole browsers to remain review-only rather than being closed automatically.
• You need supported downloads for Windows x64, Mac Apple Silicon, or Mac Intel.
• You value local monitoring and local stop history over advanced tuning panels.

What Never Spin will not do

Never Spin is not an advanced tuning tool, antivirus product, storage cleaner, or hardware optimizer. It focuses on one job: stopping a safe background app that keeps making the laptop slow while protecting current work.

Do not stack overlapping automation

Two utilities changing the same process at the same time can make results harder to understand. If you switch, disable overlapping automation first and test during a noncritical workload. Use the high CPU diagnostic to confirm that a sustained background task is actually the problem before installing another process tool.
