So I decided to just make sure the dolby audio programs I deleted were truly deleted and just reinstall it again. I became extremely worried because I love dolby audio's sound a lot. Worst is I haven't created any restore point. I just read 'preparing to remove' and find myself unable to stop it. I don't know the exact names, it happened pretty fast.
So while deleting some programs on add/remove programs on windows 10, I accidentally deleted two dolby audio programs. I have encountered a very strange and depressing problem.
