TaskMan Get in touch

How it works

A full-parity replacement for the Windows 11 Task Manager. The full technical description of TaskMan — what it does, what it is made of, and what state it is in.

The premise

An exact-parity rebuild of the Windows 11 Task Manager: every page, column, action, dialog and setting, and deliberately nothing more.

It is built on WinUI 3 with native interop through CsWin32 plus hand-written bindings for the ntdll APIs the source generator does not expose. The specification opens with a feasibility audit of which Task Manager metrics are actually reachable from user mode — the constraint that shapes the whole build.

What is included

Feature parity as the explicit goal, with a parity checklist tracked against the real application

WinUI 3 on Windows App SDK, unpackaged, x64 and ARM64

Native interop via CsWin32 with hand-written ntdll bindings where required

How it is built

TaskMan is built on C#, .NET 8, WinUI 3 and CsWin32.

It is maintained in a private repository; its history is not published.

The method behind it

Every project here starts as a written specification, and the specification stays authoritative once code exists. The repository keeps a build plan with live status, an append-only decision log recording where the implementation departed from the plan, and a handoff document describing the true current state — including the parts that are not finished.

That is why a portfolio this wide is not a shallow one, and it is why this page can describe the product without overstating it.

Current state

Prototype. Working, not yet finished.

The source is private. What this page claims is checkable against the product itself, not the repository.
