About RIVET
RIVET is made by Will Kirby, an independent developer in the UK, trading as Kirby Systems. It started in 2024 as a single PowerShell script written to stop retyping the same maintenance commands, and became a native Windows app on the Microsoft Store in July 2026.
Everything about how RIVET is built comes from one idea: a tool with this much access to your PC should show you what it is doing, and never phone home. So every change is previewed before it runs and written to a history, most changes can be undone, and there is no telemetry, no analytics and no account. RIVET is built alongside school, one release at a time, in public.
The story so far
| When | What happened |
|---|---|
| 2024 | A single PowerShell script for one machine: console output, no interface, written to stop retyping maintenance commands. |
| 15 May 2026 | RIVET 2.0 goes public on itch.io: still one file, now with a drawn HUD and typed commands. RIVET 2.1 followed. Both are now retired and free. |
| 23 July 2026 | First upload to Microsoft Partner Center. |
| 26 July 2026 | RIVET 3.0: a native WPF app on .NET 10, packaged as a signed MSIX for the Microsoft Store. |
| August 2026 | RIVET XP, a free Windows XP style task manager, released for the 25th anniversary of Windows XP. |
| 6 October 2026 | RIVET 3.6: ten languages and four new themes. |
| October 2026 | RIVET 3.7 (Spark, model sizes, about ten times lighter while idle) and, on 27 October, 3.7.5 (a first checkup that ends on one card, and cleanup reminders). Full detail on the versions page. |
