In the current project, I'm making an icon overlay. The actual implementation is completed.
And I made sure that it worked well in WindowsXP and Windows7.
But I want to appear to overlay icon immediately without restarting the explorer process.
So I found a way that SHLoadNonloadedIconOverlayIdentifiers function signals the shell and then load the nonloaded Shell Extension dll.
I make sure in the MSDN that minimum supported clinet of this function is Windows 2000 Professional.
In Windows7, this function worked fine, but it did not work in WindowsXP.
I would like to know why.
