Situation

• Building Node.js with Temporal support now states:

Temporal support is enabled by default starting in Node.js 26. Building it requires a Rust toolchain.

Windows prerequisites - Automated install with WinGet states:

WinGet configuration files can be used to install all the required prerequisites for Node.js development easily.

This is no longer true, because a Rust toolchain is required and not automatically installed. The WinGet configuration files do not install Rust.

Change

• Add the WinGet package Rustlang.Rust.MSVC to the WinGet configuration files

• Correct the configurationVersion to 0.2.0 to match $schema=https://aka.ms/configuration-dsc-schema/0.2, which is the latest version.

• Add "Rust Toolchain MSVC" to the list of installed components in Windows prerequisites - Automated install with WinGet

Verification

On Windows 11 25H2 (amd64)

Uninstall any related previously installed prerequisites from Settings > Apps, such as:

• Rust
• Microsoft Visual Studio Installer
• Python
• Python Install Manager
• Git

Uninstall:

• NASM (delete C:\Program Files\NASM)

In a PowerShell terminal, execute each of the following separately. Between each test,
uninstall Microsoft Visual Studio Installer:

winget configure .\.configurations\configuration.vsBuildTools.dsc.yaml

winget configure .\.configurations\configuration.dsc.yaml # Community Edition

winget configure .\.configurations\configuration.vsProfessional.dsc.yaml

winget configure .\.configurations\configuration.vsEnterprise.dsc.yaml

Check installation:

rustc --version
cargo --version

Expect the following versions or above:

rustc 1.95.0 (59807616e 2026-04-14)
cargo 1.95.0 (f2d3ce0bd 2026-03-21)
