Depending on the software you'll probably still have to install a codec pack. Just because the hardware is natively capable of decoding a certain codec doesn't mean the software it is running is properly instructing it how to handle a file. After all, you always need "external software" to open a media file. Windows has built those packs into WMP. The packs are automatically fetched and downloaded by the Microsoft store unless you turn off updates like you would turn off Android/iOS updates on a phone.
