The first step is to navigate to VLC’s Program Files folder and get into the skins subfolder.
You will see the .vlt file for the default skin included with your VLC installation.
Simply drag and drop the skins that you have downloaded into this folder.
Now for the next step.
Go to the Tools Menu and access Preferences.
When the Preferences Window opens go to the Interface configs section (it should display by default).
opt for Use custom skin setting and click Save.
You will need to restart VLC for the changes to take effect.
That is all there is to it.
Note: You will not need to manually restart VLC for the change to take effect.
