A PowerShell script for external customers who have provisioned a Cloud PC from the Windows 365 Dev Ready Image and want to remove all of the bundled third-party developer tools from their machine.

After Node.js is uninstalled, the script also reinstalls GitHub Copilot CLI in its standalone form so the copilot command keeps working without Node.js.

• Python 3.13 (MSI + the C:\Python313 install directory)
• Node.js LTS (winget package)
• nvm-windows (%ProgramData%\nvm and the %ProgramFiles%\nodejs symlink)
• oh-my-posh (%ProgramFiles%\oh-my-posh) and the Cascadia Code / Cascadia Mono Nerd Font variants it installs (registry + font files)
• uv tools (%ProgramData%\UVTools)
• Ubuntu WSL distribution (VHDX, install folder, and HKCU\Software\Microsoft\Windows\CurrentVersion\Lxss registry keys, including the default-user entry)
• Tool entries added to the machine PATH
• The oh-my-posh blocks in the Windows Terminal settings.json and the PowerShell Microsoft.PowerShell_profile.ps1 files for every local user

After Node.js is removed, the script reinstalls the standalone GitHub Copilot CLI via winget (GitHub.Copilot) and patches the existing npm shims (%ProgramData%\npm\copilot.ps1 and copilot.cmd) to point at the standalone executable. This keeps the copilot command — and the Start Menu shortcut — working without Node.js.

• Windows PowerShell 5.1 or PowerShell 7+
• Run as Administrator (the script enforces this)
• Internet access (winget needs it for the Copilot CLI reinstall)
• A reboot is recommended after the script completes (font cache, PATH, and WSL changes do not all take effect until next sign-in)

From an elevated PowerShell window:

cd DevReadyImage-Uninstaller
.\Uninstall-ThirdPartyTools.ps1

The script:

1. Scans the machine and prints a removal plan of everything it would touch.
2. Asks you to confirm (Y / N) before changing anything.
3. Runs each removal step, printing one section per item.
4. If Node.js was removed, reinstalls Copilot CLI standalone and verifies copilot.exe is on PATH.

A full PowerShell transcript of every run is written to:

%TEMP%\Uninstall-ThirdPartyTools_<yyyyMMdd_HHmmss>.log

Attach this file when reporting issues.

• The script deletes any Microsoft.PowerShell_profile.ps1 that references oh-my-posh rather than editing it. Back the file up first if you have custom content you want to keep.
• The Ubuntu removal calls wsl --shutdown before deleting the VHDX so the file is not locked. If the delete still fails, sign out and re-run.
• Some MSI components (Python in particular) must be uninstalled in a specific order; the script handles this with a 3-pass sort, but a non-zero MSI exit code on the first pass is normal and not fatal.
• The Copilot CLI reinstall step is skipped if Node.js was not actually present (nothing to fix up).
