Due to wmic has been deprecated. Replace wmic command in attach process with powershell command.

[ZA139]

Hi,

According to issue #744, WMIC is deprecated as of Windows 10 version 21H1 and the 21H1 semi-annual channel release of Windows Server. This utility is superseded by Windows PowerShell for WMI.

Changes:

• The PowerShell command "Get-CimInstance" is now the first option on Windows
• For older Windows versions without CIM support, it falls back to "Get-WmiObject" for legacy compatibility
• If PowerShell is not available, it automatically falls back to WMIC for maximum legacy compatibility
• No Feature Changed

Additional changes:

• Added unit tests for PowerShell process listing functionality
• Added unit tests for automatic command fallback behavior:
  • Test PowerShell command execution when PowerShell is available
  • Test WMIC command execution when PowerShell is not available
• Added unit tests for Get-CimInstance failure scenarios
• The AttachProcessProvider now accepts an optional ProcessListCommand parameter in getAttachItems and _getInternalProcessEntries, allowing callers to specify the process listing command
• Updated unit tests to use the new parameter for precise control over process command selection

Best Regards
Charles

Is it really worth adding the fallback to the old WMI cmdlet? Get-CimInstance has been present since PowerShell v3 which is included in Windows 8/Server 2012 which even now are end of life. Even older Windows versions can install PowerShell 5.1.

Is it really worth adding the fallback to the old WMI cmdlet? Get-CimInstance has been present since PowerShell v3 which is included in Windows 8/Server 2012 which even now are end of life. Even older Windows versions can install PowerShell 5.1.

Thank you for raising this! You're absolutely right from a technical standpoint – Get-CimInstance has been around since PowerShell v3 and is indeed ubiquitous.

I added the fallback logic through Get-WmiObject and even down to WMIC, mostly out of a "just-in-case" mindset, trying to maximize compatibility as a community dev for anyone who might run this in a locked-down or legacy environment.

That said, I'm not attached to the extra fallbacks. Think of this PR as a conversation starter. I'm totally fine with any of these approaches:

• Keep the full fallback chain for max compatibility.
• Simplify it (e.g., remove Get-WmiObject but keep Get-CimInstance → WMIC).
• Or just standardize on Get-CimInstance and keep things clean.

If Microsoft prefers to simplify the code and drop the legacy support, I'm 100% on board. Just let me know what you'd like, and I'll update the PR accordingly. I'll happily strip it out.
