Cannot find the right Media Pack installer for Windows 10? Look no further.
You probably tried installing this one (KB3099229_x64.msu): KB3099229 Media Feature Pack for Windows 10 N and Windows 10 KN editions (November 2015)
It didn’t work even though it does work from some people prior to April 2017.
You now need to install this one (Microsoft-Windows-MediaFeaturePack-OOB-Package.msu): KB4016817 Media Feature Pack for N edition of Windows 10 Version 1703 (April 2017)
