A random msi installer I tried doesn't show the problem, please provide specific steps to reproduce.
Install any program and then run the wine uninstaller. The program should be displayed (which means it has an entry in the registry uninstall keys. Then select the program and select remove option. The program should then be removed from the uninstaller list (meaning its entry has been removed from the registry).
