Hi, try this:

Right click on a video file.
Go to Open With and select Choose another app.
Select Windows Media Player.
Check the box Always use this app to open X files.
Choose OK.

If this doesn't work, go to Settings, Apps, Default apps. Under Video player, choose Windows Media Player. You might need to temporarily change it to something else, then back to Windows Media Player.

Hopefully this fixes the invalid registry entry.
