So I come onto the official Microsoft help website just to get linked to a YouTube video? Really? How about actually helping people here and give them the answer they need...
In the search bar, type: Control Panel
this will load up the default control panel, if you know other ways to get here then please do so.
Click "Programs"
Click "Programs and Features"
from here on the left hand screen "Turn windows features on or off" click this, this will open a new window, that will take a short time to populate.
Scroll down to "Legacy Features" then select the "Direct Play" option and click on the OK button.
Windows will now install and activate this feature, and done.. and without having to watch an annoying and advert filled video on YouTube and getting the ANSWERS from the website you EXPECT to get them from!
