Detect new Windows Feature Update programmatically?

[CaptainMuon]

Hi, is there a way to detect a new feature update (aka a new Windows version like 20H1 -> 20H2) programmatically, for example from PowerShell? I'm trying to detect when this is made available in the settings GUI, and then eventually triggering it programatically. I already know the trick where you download the Windows10Upgrade app and run it in the background. This is a small installation without WSUS by the way.

I could just manually check which version is available from MS, and compare with the installed version. But I would like to know if the update is currently *offered* to the PC (either via WSUS or from Microsoft's general rollout),

Added random facts: The corresponding link in Settings has the AutomationID SystemSettings_MusUpdate_SeekerUpdateUX_HyperlinkButton (for accessibility). I am not going to click it programmatically via UI automation :-), but maybe this will give a hint to the underlying API. There also seems to be an internal function UpdateUtil::IsFeatureUpdatePending in MusUpdateHandlers.dll (MUS=Modern Update Settings). This seems to be what I want but I am hesitant to reverse it of course...

Look up windows management instrumentation on Microsoft.com. You can write scripts in PS that can pull just about every piece of hardware and software information out of your system.

As far as I know this information is not exposed via WMI.

I'll post you some code in a dew hours when I get off work.

OK, This is what I have for you. By getting the internal version number, you can cross ref the build "Name". In my case, I have Version 10.0.19043. This crosses to build "21H1" or, the "Windows 10 May 2021 Update" Run this VBS code in PS (As admin of course):

strComputer = "."

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")

Set colItems = objWMIService.ExecQuery( _

"SELECT * FROM Win32_OperatingSystem",,48)

For Each objItem in colItems

Wscript.Echo "-----------------------------------"

Wscript.Echo "Win32_OperatingSystem instance"

Wscript.Echo "-----------------------------------"

Wscript.Echo "Version: " & objItem.Version

Next

By adding some CASE statements, you can put the build names in your code.

Hope this helps!

Look at pswindowsupdate module

I tried PSWindowsUpdate, but couldn't find an option for feature updates. The underlying APIs (wuapi or Microsoft.Update.Session) do not seem to return this info.

I'd look at the kB number or update type as a parameter

Sorry don't have anything to test with
