Completely removing the cbs packages will cause Windows Update to break. To resolve the problem, remove only the *.num files.
I created a script, but it doesn't include the "revert" function, so I asked Gemini to create another one trying to combine the functions of your script.

A clear and concise description of what you want to happen.

Script Block 1 (My Block)

function Remove-AI-CBS-Packages {
$patterns = @('AIX', 'Recall', 'Copilot', 'CoreAI')
foreach ($pattern in $patterns) {
$packages = Get-WindowsPackage -Online -ErrorAction SilentlyContinue | Where-Object { $_.PackageName -like $pattern }
foreach ($pkg in $packages) {
try {
Remove-WindowsPackage -Online -PackageName $pkg.PackageName -NoRestart -ErrorAction Stop >$null 2>$null
} catch {
Start-Process -FilePath "dism.exe" -ArgumentList "/Online", "/Remove-Package", "/PackageName:$($pkg.PackageName)", "/NoRestart", "/Quiet" -WindowStyle Hidden -Wait 2>$null
}
}
}

foreach ($pattern in $patterns) {
    $files = Get-ChildItem "$env:windir\servicing\Packages" -Filter "$pattern*.mum" -ErrorAction SilentlyContinue
    foreach ($file in $files) {
        $filePath = $file.FullName
        try {
            takeown /f "$filePath" /a > $null 2>$null
            icacls "$filePath" /grant "Administradores:F" /c > $null 2>$null
            Remove-Item -Path $filePath -Force 2>$null
        } catch {}
    }
}

}

Script Block 2 (Gemini)

function Remove-AI-CBS-Packages {
param([switch]$revert)

$patterns = @('*AIX*', '*Recall*', '*Copilot*', '*CoreAI*')
$regPath = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages'

if (!$revert) {
    Write-Host "Starting deep uninstallation of AI packages..." -ForegroundColor Cyan

    # PHASE 1: Unhide and Break Links in Registry
    $ProgressPreference = 'SilentlyContinue'
    Get-ChildItem $regPath | ForEach-Object {
        $pkgName = $_.PSChildName
        
        # Check if the package matches any of our patterns
        foreach ($pattern in $patterns) {
            if ($pkgName -like $pattern) {
                $value = try { Get-ItemPropertyValue "registry::$($_.Name)" -Name Visibility -ErrorAction Stop } catch { $null }
                
                # If hidden (2), make it visible (1) and remove owners
                if ($value -eq 2) {
                    Set-ItemProperty "registry::$($_.Name)" -Name Visibility -Value 1 -Force
                    New-ItemProperty "registry::$($_.Name)" -Name DefVis -PropertyType DWord -Value 2 -Force | Out-Null
                    Remove-Item "registry::$($_.Name)\Owners" -Force -ErrorAction SilentlyContinue
                    Remove-Item "registry::$($_.Name)\Updates" -Force -ErrorAction SilentlyContinue
                }

                # PHASE 2: Logical Removal
                try {
                    Write-Host "Removing package: $pkgName" -ForegroundColor Yellow
                    Remove-WindowsPackage -Online -PackageName $pkgName -NoRestart -ErrorAction Stop >$null 2>$null
                } catch {
                    # Fallback to DISM (more robust in some environments)
                    dism.exe /Online /Remove-Package /PackageName:$pkgName /NoRestart /Quiet
                }
            }
        }
    }

    # PHASE 3: Physical File Cleanup with Takeown
    Write-Host "Cleaning up residual files (.mum)..." -ForegroundColor Gray
    foreach ($pattern in $patterns) {
        $files = Get-ChildItem "$env:windir\servicing\Packages" -Filter "$pattern*.mum" -ErrorAction SilentlyContinue
        foreach ($file in $files) {
            $filePath = $file.FullName
            try {
                # Ensure permissions to delete system files
                takeown /f "$filePath" /a > $null 2>$null
                icacls "$filePath" /grant "Administrators:F" /c > $null 2>$null
                Remove-Item -Path $filePath -Force 2>$null
            } catch {}
        }
    }
} else {
    Write-Host "Revert Mode: To revert, you must use Windows Update or a recovery image." -ForegroundColor Orange
}

Additional context
Add any other context or screenshots about the feature request here.

I tested the first script at the company where I work and it doesn't break Windows Update. If it's not possible to implement this, separate the action of this block from the rest of the script.

[zoicware]

after removing the packages with dism the files get removed too so you cant just only remove the mum files

if you need to repair this youll need to use dism with restorehealth or resetbase etc read #77 to see what other people have used to restore these... if there is a consistent way to restore them then ill add that to the script

Okay, I'll look at #77.

I'm going to close this topic.
