Yesterday I get new Nvidia drivers and installed all features with clear installation (as always). Today, when I do systen restart, I can's see Nvidia icon in system tray. I tied to unistall Bitdefender and it apper there. I think that Bit uncheck "show icon in the system tray" (it located in Nvidia control panel) so that's why it don't appear there... It happen only after system restart, if I shut down PC and run it then, Nvidia is in the tray..Also I think it happen after Nvidia update (maybe not) because it didn't happen some days ago (before Nvidia update).
