问题
So I split my window from the main tab group via IPropertyStore via SHGetPropertyStoreForWindow like so:
IPropertyStore_SetValue(pps, PKEY_AppUserModel_ID.address(), 'Contoso.Scratch');
pps->Commit();
Then the user later decides he wants to rename it so with my feature he does:
IPropertyStore_SetValue(pps, PKEY_AppUserModel_RelaunchCommand, customLaunchPath);
IPropertyStore_SetValue(pps, PKEY_AppUserModel_RelaunchDisplayNameResource, 'my first name');
pps->Commit();
This works successfully for the first time. But if he wants to change just the RelaunchCommand and RelaunchDisplayNameResource again it won't work unless I change the ID as well.
I gave RelaunchCommand and RelaunchDisplayNameResource as exmple here, in my real case scenario the user ALSO wants to change the icon but the same issue, it works a first time per ID. Anyway to run multiple times without having to change ID every time?
Thanks
PS:
The other big reason for this solution, is that one of my windows already has a System.AppUserModel.ID and is already pinned. I want to just change the icon/relaunchCommand/etc, if i change the System.AppUserModel.ID then it will effectively unpin it. :(

The solution to this topic is the workaround I am using:
Detecting Application Pin State
Before setting property I test if it's pinned by looking in folders of:
%AppData%\Microsoft\Internet Explorer\Quick Launch\User Pinned\ImplicitAppShortcuts%AppData%\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
And I do a IPropertyStore::getValue on all the shortcuts, if it matches my AppUserModelID, then I change the icon, label, etc on that, which right away updates it in the taskbar.
This works but I'll leave this solution unaccepted as it's not documented so probably not the right way to go about it.
If the AppUserModel.ID is not found among the shortcuts, the i just to IPropertyStore::setValue on the windows of my application (I have to do on each window, i cant find a way to do it across the whole application)
