See #120431 (comment)

We need to make https://github.com/microsoft/vscode-windows-process-tree context-aware.

To verify: code review, or clone the vscode-windows-process-tree repo and ensure tests pass locally.

@rzhao271 see microsoft/vscode-windows-process-tree#31 which is a PR to add automated GH action to run tests on Windows.
