Update of application Icon in Windows-7 Taskbar - winapi

I have a normal MFC Application with an embedded icon. If I start the application, the icon is shown inside the windows-7 taskbar.
But when I change the icon inside the resources, rebuild the application and start it, the taskbar doesn't show the current icon, but the icon from the first run.
There is no special code inside the application that does something specific with the windows-7 taskbar.
Is there a way, (in C++) to tell the windows-7 taskbar to show the current icon?

Did you empty/delete the shell icon cache?

I believe that if you rebuild an application, but it's still called by the same name, then explorer doesn't think it should reload the icon, even though the new icon is the only one in the app.
If you were to release the program, no-one else would have this problem since the first version of the app would have the new icon, but for your own purposes you can call SHChangeNotify(); from shell32.dll to refresh your own view of the icon.

did your remove the previous icon from resource....and assign the new icon to the file..too after putting in the resource...might that would work....

Desktop shortcut icon overriding app icon

We have an application that is installed with a desktop shortcut icon that is different than the application icon. So, the result we are aiming at is:
a desktop shorcut with icon A, pointing to our application
once clicked, the application will launch with it's own icon B
However, the observed behaviour is that our application is launched with the shortcut icon A visible in the start menu bar, and the proper app icon B visible in the title bar. Is there an option to override this behaviour?
We are using InnoSetup for our installer, if that matters.
I found one solution - having the process restart itself will fix the problem. It's pretty clumsy, but it works. I'll mark this as an accepted answer unless somebody has a better suggestion.

windows taskbar and open programs

Is there any way to place the taksbar icons of all the open apps in Windows 8.1 next to each other automatically?
Say I open an app whose icon is on the far left, next to the start button, and I want said icon to appear to move to the far right of my string of icons, next to all my other open programs, automatically.
Is there any way to do that?
Do you mean, for applications that you have already pinned to the taskbar, you want them to move over to the end of the line of open programs? I don't think it is possible to set this option automatically. However, you can manually move them to where-ever and they will remain pinned. For other taskbar settings, just search Taskbar and the settings box will come up.

windows 7 - some icons disappeared on start menu, desktop, programm and features

some of my icons disappeared, for example the whole Microsoft office icons, they disappeared in the start menu, programm and features and also on the desktop.,
what i've tried is , to go to the folder of the exe, and pin it to the taskbar this will also show up the icon for unknown exe. changing icon doesnt work for the shortcuts, its disabled.
then i made a new shortcut and put it on the desktop that will show up the original icon. so i can recreate the start menu and the desktop, but still the icons are missed in programm and features.
i also tried to delete the icon cache db a 100 times but that doesnt work.
has anybody a solution?
does somebody know where the icon references are stored in the registry. i dont know where to start
Rebuild the icon cache.
If that doesn't work look here for a quick and easy fix.

Change icon of group in taskbar (Win7)

Using LoadImage I changed the icon of all the windows in a group. However the group icon does not change. How can I get the corresponding group to a window and set its icon?
The group icon comes from the EXE file itself (in the case of multiple EXEs contributing to the same group, I imagine the taskbar has some algorithm to decide which EXE to pull the icon from). There is no official API to change the group icon. You would have to manipulate the Taskbar directly, which is not impossible but not trivial either.
Update: I just came across the following answer, maybe it will help you:
https://stackoverflow.com/a/219128/65863
Update: Apparently the Registry value in the above link only applies if the app is pinned to the Taskbar.
Your issue is this: The icon does infact take the icon of the first WINDOW, not exe. HOWEVER, after setting the icons, you have to right click on the icon in the taskbar, then pin it, then unpin it. On unpin the taskbar icon now takes the first windows icon.
I don't know how to programatically do this to maybe #RemyLebeau knows. Maybe setClassLongPtr? Not sure.
Now when it's pinned you want to make it use the same icon, so set the registry value like #RemyLebeau suggested.
Also I don't know how to explain this, but after unpinning, and the icon takes, if you open the jump list, the icon reverts back to the exe's icon. This may be fixed with the registry setting for pinned icon, I'm not sure.
Wow so Win7 taskbar is so tweakish.
Edit: I tried setting my registry values and the icon didnt work. It might have to do something with: the registry entires that i found for TaskbarGroupIcon all had a data value ending with a comma and a number (ex: ,-4 in %SystemRoot%\System32\imageres.dll,-4)

Windows Mobile 6.5 Running Program List Icon

I've got an windows mobile 6.5 application I'm developing and am having trouble with one icon. At the top right hand of the screen there is an icon that, when clicked, will display a list of programs running the background with the option to close them.
When my program is in this list, it's icon does not show up as the others do.
I'm my exe I've got an .ico for 16x16, 22x22, 32x32, 36x36, 44x44, 45x45, 60x60, and 64x64, with the optional 90x90 png and registry setting in my cab.
What am I missing?
I'm just guessing here, but is this an HTC phone? Stock Windows Mobile does not have a "task list" icon in the system tray, so this task list is provided by the OEM. You would need to find out how they are obtaining the icon.
Chances are they are not obtaining it from the cab, but are actually getting it from your top level app window. You should check you're specifying the right icon in your WNDCLASS structure when calling RegisterClass. It is pretty common in WM to forget this because normally this icon is not visible.
Windows Embedded Handheld (Windows Mobile) 6.5/6.5.3 Appications use the exe embedded ico files only if there is no icon via registry available. In those cases the icon also look very ugly in the start menu. So you will have to add a registry entry to an icon file.
[HKEY_LOCAL_MACHINE\Security\Shell\StartInfo\Start\MyApp.lnk]
"Icon"="\Windows\myapp.png"
