chore(docs): add Windows wmic information to README

[MikeMcC399]

• Relates to Error: kill EPERM  #384

Issue

start-server-and-test uses the npm package ps-tree@1.2.0, with cross-platform support, to implement the shut down server functionality.

As shown in the ps-tree > README > Windows section, ps-tree makes use of the wmic utility on Windows. This is the "Windows Management Instrumentation command-line" utility executable, also referred to as WMIC (upper case).

WMIC has however been deprecated by Microsoft since Aug 2016 and is removed by default in Windows 11 24H2 and Windows Server 2025.

There is currently no higher version of ps-tree available which removes the dependency on WMIC. There are two associated open PRs indexzero/ps-tree#59 and indexzero/ps-tree#62 which have not received any maintainer feedback.

Change

Add information into the README > Install section for Windows 11 24H2 and Windows Server 2025.

  The WMIC utility is deprecated in Windows 10, version 21H1 and the 21H1 General Availability Channel release of Windows Server. This utility is superseded by Windows PowerShell for WMI. Note: This deprecation applies to only the command-line management utility. WMI itself isn't affected.

  [Update - January 2024]: Currently, WMIC is a Feature on Demand (FoD) that's preinstalled by default in Windows 11, versions 23H2 and 22H2. In the next release of Windows, the WMIC FoD will be disabled by default.

The issue also affects Windows Server:

Features removed or no longer developed starting with Windows Server 2025 includes the section

• Features we're no longer developing which says:

  Windows Management Instrumentation Command line (WMIC)

  Beginning with Windows Server 2025, WMIC is available as a feature on demand (FoD) which can be added with the DISM /Add-Capability command. It will be removed from Windows in a future release. PowerShell for WMI replaces the WMIC tool. Use PowerShell or programmatically query WMI as a replacement for WMIC.
