Online radiostation starts playing by itselfs !?!

Hi guys,

I have a strange thing going on...
Every once in a while a local radiostation comes on without me asking for it.
After a long search, i found that a process called "window.media.backgroundplayer.exe" is doing this .
When i stop that process, the music stops...
But sometimes the next day and sometimes the next week or so, it's there again...
Can someone tell me why this is happening ?
I have Windows 10 Pro (64bit) on a desktop I5-processor

Thanks for any info ;-)
Luc
