Process Lasso is free to use indefinitely, but some advanced features may disable over time and a nag may be shown. Process Lasso Pro unlocks everything, with a lifetime license that is a one-time payment. Commercial use requires a license within 30 days of deployment.
A Process Lasso Pro lifetime license is a one-time payment. It includes every minor and major update, forever: You never pay again to stay current.
| Lifetime license | One-time price | Covers | Updates |
|---|---|---|---|
| Single PC | $39.95 $23.97 | 1 PC, home or commercial use | All updates, forever |
| Entire Home | $59.95 $35.97 | Up to 5 PCs in one home, non-commercial use | All updates, forever |
You can move a license to a new PC or a fresh Windows installation at any time by activating it there. Businesses buying for more PCs can save with volume packs, and servers need Process Lasso Server Edition. The licensing documentation covers virtual machines, Remote Desktop Services and the full terms.
Every Pro feature can be tried during a short trial after you install. After the trial, the free version keeps every feature marked Yes below, and adding rules for features marked Trial only needs a Pro license.
