Once i uninstalled Windows Blind, all my sound drivers kept getting deleted (or not in use because it says no audio device) and whenever i restart my computer it's set to "Windows Classic"
windows blinds is pretty horrible, though I cant see how it would fuck with your sound drivers unless it was using custom sounds or something.
Windowblinds can rightfully fuck your computer up. It's not worth it to install. Rather, just stick to using custom Visual Styles by patching uxtheme.dll . Solution to your problem? reinstall windows.
just boot recovery or use the windows reinstall and dont use the destructive recovery setting, that way you reinstall windows and keep all of your precious data.
