Add a resumable PowerShell setup flow for Windows developer machines by AmelBawa-msft · Pull Request #93 · microsoft/WindowsDeveloperConfig

AmirMS (AmelBawa-msft) · 2026-08-18T23:42:18Z

Introduces a PowerShell implementation of the developer workstation setup that
runs from a single command, checks every change before applying it, and continues
across the reboot WSL requires.

The release-copy updates move to a separate PR, so this branch no longer touches windows-dev-config/. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: fa27b7a2-0eb1-4970-927c-340739ecbdc1

CLI mode now matches module mode:
return-not (Test-DevConfigWingetUpgradeAvailable-Id $Id)
The helper runs winget list --upgrade-available and matches the package id. Exit codes are no use here — winget returns 0 either way — and the messages are localized, so the id is the only stable signal.
Checked against real winget on a VM, plus unit tests for the upgrade-available, no-match and failed-query cases.

Based on trying this out, I think this should be Microsoft.PowerToysWin32
