Some functions out of my setup script for installing Pwsh & PwshPreview via Microsoft update

InstallPwsh-StableOrPreview.ps1

function Install-PwshPreview {
    $pwshRegPath = "HKLM:\SOFTWARE\Microsoft\PowerShellCore"
    $previewPath = Join-Path -Path $pwshRegPath -ChildPath "InstalledVersions\39243d76-adaf-42b1-94fb-16ecf83237c8"
    if (!(Test-Path -Path $previewPath)) {
        $null = New-Item -Path $previewPath -ItemType Directory -Force
    }
    Set-ItemProperty -Path $pwshRegPath -Name UseMU -Value 1 -Type DWord
    Set-ItemProperty -Path $previewPath -Name Install -Value 1 -Type DWord
}
function Install-Pwsh {
    $pwshRegPath = "HKLM:\SOFTWARE\Microsoft\PowerShellCore"
    $StablePath = Join-Path -Path $pwshRegPath -ChildPath "InstalledVersions\31ab5147-9a97-4452-8443-d9709f0516e1"
    if (!(Test-Path -Path $StablePath)) {
        $null = New-Item -Path $StablePath -ItemType Directory -Force
    }
    Set-ItemProperty -Path $pwshRegPath -Name UseMU -Value 1 -Type DWord
    Set-ItemProperty -Path $StablePath -Name Install -Value 1 -Type DWord
}

Install-PwshPreview
Install-Pwsh

This I think actually also needs the Receive updates for other Microsoft products when you update Windows setting to be on which I've previously done manually but I am lead to believe is done via

Set-ItemProperty 'HKLM:\Software\Microsoft\WindowsUpdate\UX\Settings' -Name AllowMUUpdateService -Type DWord -Value 1

I reckon adding these below regkeys upfront (that the msi installer uses) would also ensure the installation goes as required
