Could not find MicrosoftWindows.LKG.AccountsService\AppxManifest.xml when running #disable ai context menu extensions

[ptlambert]

Describe the bug
When I enable only the first option in the GUI to Disable Registry Keys and then click Apply, it throws a pop-up error right after the section in the PowerShell console that says:
Disabling AI Experiment Program In Paint...

The error dialog says:
An error occurred: Could not find file C:\Windows\SystemApps\LKG\MicrosoftWindows.LKG.AccountsService_cw5n1h2txyew\AppxManifest.xml

Clicking OK to the error dialog reveals no further progress in the PowerShell console, however I am able to Cancel the GUI app at that point which cleanly terminates the script.

FYI, I downloaded and opened RemoveWindowsAi.ps1 in the PowerShell ISE and was able to force the Disable Registry Keys section to proceed to completion without any errors by snipping out this section of the script:

    #disable ai context menu extensions
    #these clsids are not always the same despite what most people seem to think when using this method so we need to get them for the user
    if ($revert) {
        $keys = Get-ItemProperty 'HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked' -ErrorAction SilentlyContinue  | Get-Member -ErrorAction SilentlyContinue | Where-Object { $_.Definition -like '*copilot*' -or $_.Definition -like '*designer*' }
        if ($keys) {
            foreach ($key in $keys) {
                Reg.exe delete 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked' /v "$($key.Name)" /f *>$null
            }
        }
    }
    else {
        $aiContextMenus = @(
            'AskM365Copilot'
            'AskCopilot'
            'CreateWithDesigner'
        )
        $contextMenuExtensions = (Get-AppxPackage -AllUsers | Get-AppxPackageManifest) | ForEach-Object { $_.package.Applications.Application.Extensions.Extension.FileExplorerContextMenus.itemtype.verb } | Select-Object  Id, Clsid -unique
        foreach ($ext in $contextMenuExtensions) {
            if ($aiContextMenus -contains $ext.Id) {
                Reg.exe add 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked' /v "{$($ext.Clsid)}" /t REG_SZ /d "$($ext.Id)" /f *>$null
            }
        }
    }

So something in this code block is triggering that error dialog...

To Reproduce
Run PowerShell as Admin, paste full "Launch with UI" command from GitHub into PowerShell console and press
Enter, wait for script GUI to appear, deselect all options except Disable Registry Keys, press Apply button, wait for the console to display:
Disabling AI Experiment Program In Paint...
... after which the error dialog is thrown:
An error occurred: Could not find file C:\Windows\SystemApps\LKG\MicrosoftWindows.LKG.AccountsService_cw5n1h2txyew\AppxManifext.xml

Additional context
This is Windows 11 IoT Enterprise LTSC 2024 which is very pared-down by default. I did not explicitly remove that "MicrosoftWindows.LKG.AccountsService" AppX package (nor any other packages) myself. However I do have the latest version of O&O ShutUp10++ version 2.x installed and nearly all items enabled, including all of the remediations on the "Copilot" tab. It's possible that O&O ShutUp10++ uninstalls some AppX packages via the options on that Copilot tab but I really don't know one way or another...

P.S. You are doing God's work here! (I just sent you a donation...)

the above commit should silence this error see if it fixes ur issue

thanks! ❤️

Thanks for jumping right on this... Unfortunately I'm still seeing the same error, even when downloading your updated RemoveWindowsAi.ps1 and running it directly in PowerShell ISE. Snipping that section out of the script still solves the problem. :'(

Hah! I just had a peek into C:\Windows\SystemApps\LKG. There are three AppX-named folders there, however all three (including this one) have nothing but a hidden microsoft.system.package.metadata folder inside of them. No expected AppxManifest.xml file (or anything else but that hidden folder) in any of these three package folders...

... and that hidden microsoft.system.package.metadata folder is empty in all three of these AppX package folders:

DDG search on C:\Windows\SystemApps\LKG indicates that these empty AppX folders are quite problematic, especially since PowerShell Get-AppxPackage only seems to check for the presence of the main package folder? Anyway, looks like you just need to check for the actual manifest file before iterating the collection of so-called "packages"...

some errors in ps cant be skipped with error action so yea have to check for the file manually first... thanks the detailed issue (this is hard to come by now days XD)

[ptlambert]

Thanks, looks and works good now. I downloaded your latest RemoveWindowsAi.ps1 and ran it in the PowerShell ISE. "Disable Registry Keys" is no longer throwing any errors on my wonky system (the rest of the script is working fine as well).
