[Bug] (Architecture checking) - WMIC deprecated in Windows 10 21H1 and Windows 11

[CK6853]

Pretty sure I know what went wrong and how to fix, but I'll answer the standard questions anyway and put my own thoughts at the bottom.

What were you trying to install (or what else went wrong)?

While running a WebInstall for Caddy, webi-pwsh.ps1 had an error "The term 'wmic' is not recognized..."

What exactly did you do?

On a machine running Windows 11. Ran "curl.exe https://webi.ms/caddy | powershell" as per https://webinstall.dev/caddy/

What went wrong?

Which OS did you try on?

Windows 11 (Business, 24H2), through WSL (Ubuntu 24.04.1)

What type of computer (i.e. laptop, desktop, Raspberry Pi)?

Laptop

My fix

As per this page, WMIC is deprecated in newer versions of Windows (though WMI itself is not). I solved the issue locally by replacing the line wmic os get osarchitecture with (Get-WmiObject -Class Win32_OperatingSystem).OSArchitecture in both webi/webi-pwsh.ps1 and _webi/package-install.tpl.ps1. This alternative works on both older and newer versions of Powershell, and outputs in a similar enough format that related code works with no additional changes.
