Hi Eddie. I'm Greg, an installation specialist, 9 year Windows MVP and Independent Advisor, here to help you.
Windows Media Player 12 is included in Windows 10: https://support.microsoft.com/en-us/help/17615/...
If you cannot find it after typing it into Search box, then go to Settings > Apps > Programs & Features, choose Turn Windows Features On and Off, expand Media Features, tick the box for Windows Media Player, Save and restart PC.
If that doesn't help then go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...
Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue with the other steps to go over your install most thoroughly.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
