TaskMan Get in touch

How it works

A rebuild of the Windows 11 Task Manager, feature for feature. What TaskMan does, what it’s built with, and how far along it is.

The premise

A rebuild of the Windows 11 Task Manager that matches it exactly: every page, column, action, dialog and setting, and nothing extra.

It’s built on WinUI 3, using CsWin32 for native calls plus hand-written bindings for the ntdll functions CsWin32 doesn’t cover. The spec starts by working out which Task Manager numbers can actually be read from user mode, since that decides what the rest of the build can do.

What’s included

Matching the real Task Manager is the goal, tracked with a feature checklist

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

Native calls through CsWin32, with hand-written ntdll bindings where needed

How it’s built

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

It lives in a private repository, and its history isn’t published.

How the work is done

Every project here starts as a written spec, and the spec stays the source of truth once there’s code. The repository keeps a build plan with current status, an append-only decision log of where the code departed from the plan, and a handoff document that describes where things stand, including the unfinished parts.

That’s how one person keeps this many projects moving, and it’s what this page is written from.

Current state

Prototype. Works, but isn’t finished.

The source is private, so the way to check what this page says is to use the product.
