Realtek HD audio manager missing

[nikos_gevre]

2 days ago i updated my audio drivers through driver booster. now i reallised the hd audio manager is missing. i cant open it. not even my 5.1 surround system is working for some reason. i downloaded the audio driver from my mobo support page (asus maximus vii ranger) but when i try to install it it says "win10 not supported" or something like that. then i tried to download and re-install the audio driver from the realtek site itself and still nothing happened. the hd audio manager is still missing. long story short, i tried to restore my windows 10 at the restore point created 2 days ago before the update of the driver but windows is popping a message saying "access denied, please disable your antivirus and try again". i disable my antivirus i try again and the same message pops... i will post the error windows is giving me below.
