I updated from 7100 to 7600.16385 at the weekend - a fresh install. All appears to have gone well apart from the lack of ID3 tags on my MP3s... all 17000+ of them.
My MP3's are stored on an external drive, but my previous Windows 7 installation had Public music pointed to that folder. Once I had 7600.16385 back up and running it told me I needed to take ownership of the music folder which I duely did.
Now that has completed I can access my music but I still have a padlock symbol on my music folder, and every single ID3 tag from my music no longer exists.
Any idea what could have happened? Have they really been deleted? Please say that isn't the case!!
