How I fixed broken Home Share under iTunes in Windows

Every once in a while my "Airplay" icon disapears under Windows iTunes. I have no clue why but it happens but it does. My guess is too many ios devices connecting and syncing at once somehow corrupts a config file.

Even after a reboot its still gone. I know my network is fine as all my other iOS devices such as my iphone and my kids can still select out 2 Apple Tvs to Airplay to,

Anyways, my fix is this:

1. close iTunes
2. DELETE ALL files and folders in this folder: C:\Users\<your username>\AppData\Local\Apple Computer\iTunes\*.*
3. restart iTunes and your Airplay shoulb be back.
4. my library and playlists are all fine
