Here's what you need to do because iconita Sound & Volume to appear again in System Tray:
– open Registry Editor (Go to Start If you taste regedit in Instant Search);
– in the menu Edit Select Find, taste IconStreams and click on OK. In cateva secunde vor aparea doua rezultate in partea dreapta a ecranului, IconStreams and PastIconStreams. Right click on each of them and then Delete.
