If the standard window was created with FCF_TASKLIST it is not necessary to call WinChangeSwitchEntry; WinSetWindowText, on its handle, changes the title bar and task list text.
If you want to change a few fields, not many, it is advisable to initialize the switch control structure via WinQuerySwitchEntry. Then modify those fields and call WinChangeSwitchEntry for the update.
