why does my itunes llibrary disappear when i click on song

Hi macrewdas68,

Since this issue happens in a new user, that suggests that the issue is with iTunes itself.

Even though you've already reinstalled iTunes, we recommend you reinstall again, following the exact steps for Windows 10 found in this article:

Remove and reinstall iTunes and related software components for Windows 7 and later - Apple Support

Test after you go through the article, and see if iTunes is working as it should.

All the best.

Hi macrewdas68,

Thanks for reaching out here in the Apple Support Communities.

It looks like you're having an issue with your iTunes library in Windows 10 and we're glad to help figure out what's going on.

If your library is still available, back it up and restore it before doing more troubleshooting:

Back up and restore your iTunes library on your PC - Apple Support

Some more information will also be helpful:

• When did this issue begin happening?
• Is anything different from when it was working until now, such as a software update?
• Does this happen with all songs, or a particular song?
• How do you get your iTunes library back after it disappears?

Take Care.

Hi macrewdas68,

Those are great details.

Since this began happening right after upgrading to Windows 10, check out the steps in this article to help isolate the issue a bit more:

If you have problems playing music in iTunes on PC - Apple Support

If those steps don't help, try creating a new user on your PC, and see if iTunes plays correctly there. That will let you know that something isn't working correctly in your regular user account.

All the best.
