Windows 10: ITunes or Windows file deletion issue?

As a result of a disastrous Windows 10 upgrade that had to be corrected by Windows Help techs doing re-installation my music was moved off to a local drive, then later back on to my computer. When Itunes was reinstalled had major issues such as duplicate files (perhaps due to playlists not transferring properly), Followed Apple tech advice and deleted duplicates, gave up on playlists and intended to rebuild. Overnight, however all my previous music seems to have disappeared (ITunes can't find it). That music was present yesterday cause I played it. Was primarily mp3 and CD imports. Probably a third of my library that was functioning properly yesterday is gone. mp4s and ITunes purchases all survived.

The reason I ask the question in this Win10 forum is Apple specifically told me today they would never delete and it is a Microsoft Windows 10 issue. Of course the senior tech I got to did not have good reason why, he simply said was something on my machine that was deleting particularly files like mp3s and CD imports.

I have had my PC (2012) checked out hardware wise and bios and looks OK to the local hardware folks. Installed a new harddrive just to be sure. Windows did not have issues when last installing and has run well although I have only MS apps, Google apps, and Itunes on the machine at this point.

Just checking if anyone has seen such an issue with Windows 10 elsewhere. and verifying that Apple is attempting to dodge. I'll remain open to answers!!

Thanks for any help

Try removing the iTunes Library.xml file in the iTunes folder.

Disconnect your phone, close the sync app, and close iTunes. Delete the iTunes library.xml file in the iTunes folder. The iTunes folder is found in your Music folder by default.

**WARNING**: There are two very similar files in the iTunes folder: iTunes Library.itl and iTunes Library.xml. Sometimes, the "other" file does not have the .itl file extension. Make sure you
DO NOT DELETE the .itl file. ONLY delete the XML file. If you can't see any file extensions, make sure they're on for Explorer. Sometimes, you may also find a file called iTunes
Music.xml. Delete this too.



Also delete the sync app's settings.



For Windows 7 open the Start Menu, copy the line below into the search box and press Enter.

For Windows 8, open the Search charm, copy the line below into the search box and press Enter.

%localappdata%\Microsoft\

Find the folder called "Windows Phone" and delete it.

After you delete the iTunes Library.xml file, open iTunes and give iTunes up to half an hour (depending on library size and network speed) to fully recreate the XML file. Now open the sync app, setup a sync relationship with your phone and try syncing again.

Also delete the WP7 Connector's settings. Open a Finder window and from the menubar, go Go>Go to Folder and put this in:

Find the folder called "Windows Phone 7 Connector" and drag it to the Trash.
