Set-DesktopWallpaper : Error HRESULT E_FAIL has been returned from a call to a COM component.

Cześć!

Ref: PowerBGInfo issue #18.

Invoking Set-DesktopWallpaper -Index 0 -WallpaperPath C:\BGInfo\FooBarBackground.jpg on a Windows 11 24H2 (26100.3775) computer, elevated, generates the following error, if I have previously connected via RDP:

Set-DesktopWallpaper : Error HRESULT E_FAIL has been returned from a call to a COM component.
At line:1 char:1
+ Set-DesktopWallpaper -Index 0 -WallpaperPath C:\BGInfo\FooBarBackgrou ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Set-DesktopWallpaper], COMException
    + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,DesktopManager.PowerShell.CmdletSetDesktopWallpaper

Note that the following works on the same machine whether or not I've used RDP (don't know if it's of any help though):

Add-Type -TypeDefinition @"
using System;
using System.Runtime.InteropServices;

public class Wallpaper {
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    public static extern int SystemParametersInfo(int uAction, int uParam, string lpvParam, int fuWinIni);
}
"@

[Wallpaper]::SystemParametersInfo(20, 0, "C:\BGInfo\FooBarBackground.jpg", 3)

I see the same error, calling Get-DesktopWallpaper, with no parameters:

Get-DesktopWallpaper : Error HRESULT E_FAIL has been returned from a call to a COM component.
At line:1 char:1
+ Get-DesktopWallpaper
+ ~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Get-DesktopWallpaper], COMException
    + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,DesktopManager.PowerShell.CmdletGetDesktopWallpaper

Steps to reproduce:

• Boot machine
• Log in via RDP
• Disconnect from RDP without logging off
• Connect locally as the same user (i.e. retaining the previous login session)
• Run Get-DesktopWallpaper in PowerShell prompt

I'll take a look what we can improve and will publish preview and see how that goes

Dzięki Przemysław!

Potentially fixed by:

• Fix COM wallpaper error after RDP #10

Can you install-module DesktopManager -Force -AllowPreRelease and test it, seems to work for me

I've reconnected multiple times, even retested reconnection with lower resolution

[robpomeroy]

Wow, that's an incredibly quick response! I've initially tested this and am seeing the same error, but that may be due to conflicting module installations.

I've finished for the day, so will take a look at this again tomorrow and report back.

Many thanks!

I'm sorry to report the pre-release does not work for me:

PS C:\Users\Rob> Get-Module -ListAvailable -Name DesktopManager


    Directory: C:\Program Files\WindowsPowerShell\Modules

    + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,DesktopManager.PowerShell.CmdletGetDesktopWallpaper

(This is with the same steps to reproduce - i.e. connect via RDP at least once, to trigger the exception.)

[PrzemyslawKlys]

i'll try to release new version soon. Maybe something went wrong in the publish part. But that's how i was testing it ;)

[PrzemyslawKlys]

Can you try new version? Delete old versions, install new one, confirm with Get-Module -List DesktopManager and try it, i'll do the same

[PrzemyslawKlys]

To me it workks

Pre-release 2 shows the same behaviour unfortunately. First I invoke it twice, at the local console. Then I connect via RDP and invoke it a third time, whereupon it fails:

PS C:\Users\Rob> Get-DesktopWallpaper -Index 0
C:\BGInfo\Output\FooBarBackground_PowerBgInfo.jpg
PS C:\Users\Rob> Get-DesktopWallpaper -Index 1
PS C:\Users\Rob> Get-DesktopWallpaper -Index 0

    + CategoryInfo          : NotSpecified: (:) [Get-DesktopWallpaper], COMException
    + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,DesktopManager.PowerShell.CmdletGetDesktopWallpaper

This seems to be the correct release version:

PS C:\Users\PURCHASES> Get-Content "C:\Program Files\WindowsPowerShell\Modules\DesktopManager\3.1.0\PSGetModuleInfo.xml" | Select-String 'N="Version"'

      <S N="Version">3.1.0-Preview2</S>

I'm seeing this problem in 24H2 (build 26100.3775). Does this match your Windows build?

Does the COM exception need to be caught elsewhere in the code path? (Apologies for the suggestion - I don't know C# and am struggling to trace this.)

I'm going to run the June updates (including KB5063060) and see if that makes a difference. I will report back. Thank you for your patience, Przemysław.

[PrzemyslawKlys]

ok, dso maybe i need to connect to Local, then to rdp, i did only rdp, disconnect, reconnect and it works, i am testing it on server 2016, i'll try to see if there are nyother issue that can be prevented

[robpomeroy]

After the update, now on build 26100.4351, the fault is still present. I'll try some other Windows 11 machines, to see if it is specific to this one computer. I'll update this issue after that.

[PrzemyslawKlys]

Lemme give you new version with better exception handling and lets see

[PrzemyslawKlys]

Try new installation Preview3 please
