AHK Wallpaper Change doesn't persist

[meteor1942]

So I have a snippet of code that works as expected - successfully changes the wallpaper on the desktop using:

Code: Select all

	; Update system wallpaper
	SysParamInfoResult := DllCall("SystemParametersInfo", UInt, 0x14, UInt, 0, Str, wallpath, UInt, 1)

Strange thing I've noticed on my Windows 11 desktop, is that if I switch to another virtual desktop (via task view for example) and come back to the first virtual desktop, the changed wallpaper is gone. Replaced instead by whatever I had on there before the AHK script changed it. For further context - I have 2 different virtual desktops, each of which was assigned a different wallpaper (to distinguish the desktops easily) via the Setting>Personalization>Background menu in Windows 11.

To reiterate, the script succeeds in changing the wallpaper, except that the change doesn't persist if I switch away and then back to the said virtual desktop. Any ideas how I might be able to make the change persist?

You can try to use 0x0003 as last parameter (fWinIni), this is the script i use on win10/11 .

DllCall("SystemParametersInfo", uint, 0x0014, uint, 0x0000, str, sfile, uint, 0x0003)

SPIF_SENDWININICHANGE = 2
SPIF_UPDATEINIFILE = 1


[optional] If a system parameter is being set, specifies whether the user profile is to be updated, and
if so, whether the $WM_SETTINGCHANGE message is to be broadcast. This parameter can be zero if you don't want
to update the user profile or it can be one or more of the following values:
$SPIF_UPDATEINIFILE - Writes the new setting to the user profile
$SPIF_SENDCHANGE - Broadcasts the $WM_SETTINGCHANGE message after updating the user profile
