Realtek driver issue Windows 10

[ko260]

I know this might be a strange one but I think my friend went and removed the permissions for the realtek audio driver to stop it auto reinstalling, They now want to reinstall the driver once more and they are getting access denied even when using admin. I tryed to help but I am not 100% sure how to go about fixing it any people would be much appreciated

Try going into device manager, right clicking the audio, uninstalling and then ticking "deleted driver files"

 

Then let Windows reinstall, or download from the manufacturer site
