Very Strange.

I see that WMIC is indeed deprecated quite a while back, and they must be removing it from very new builds of windows.

Hmm. It should only be falling back to using wmic if it can't find PowerShell (either powershell.exe or pwsh.exe)

Ah, I see where it's going wrong. Yeah, that's a bug.

If you are brave, and want to see if you can make a quick fix and unblock that, you can attempt the following.

open the file C:\Users\[YOURUSERNAME]\.vscode\extensions\ms-vscode.cpptools-1.22.11-win32-x64\dist\src\main.js

and replace the findPowerShell() function (around line 88628) with the following and then restart vscode see if that fixes it quickly. (Back up the main.js file first!)

The function is incorrectly returning on the first time it throws, and it really shouldn't be.

function findPowerShell() {
    const dirs = (process.env.PATH || '').replace(/"+/g, '').split(';').filter(x => x);
    const exts = (process.env.PATHEXT || '').split(';');
    const names = ['pwsh', 'powershell'];
    for (const name of names) {
        const candidates = dirs.reduce((paths, dir) => [
            ...paths, ...exts.map(ext => path.join(dir, name + ext))
        ], []);
        for (const candidate of candidates) {
            try {
                if (fs.statSync(candidate).isFile()) {
                    return name;
                }
            }
            catch (e) {
                // ignore, continue (should not actually return here) 
            }
        }
    }
}

that should unblock you - if you can test that and it works, I'll put the fix in.
