Q: How to stop iTunes from opening up on Windows startup?

On Win 10, you should be able to access the list from Task Manager, Startup tab.  It is OK if "iTunes Helper" is in that list, but "iTunes" itself should be removed if it is there.  Does that work for you?

I see iTunesHelper on that list, but not iTunes. I restarted my PC, and iTunes still starts up automatically.

OK, sorry I cannot reproduce that problem, but maybe somebody else here has some ideas.

I am having the same issues. iTunes keeps opening up when windows starts... I have disabled everything I have found and still nothing. Please if anyone can help us that would be appreciated.

Same issue here.  Very annoying!

Are you running Plex or Python by chance?

I also was having the same issue and it was driving me bonkers. Turning on the option Share iTunes Library XML with other applications fixed the issue on my end.

"The generation of the XML is now optional in iTunes 12.2 - check Preferences > Advanced and set the option Share iTunes Library XML with other applications.In order to fix it, simply turn the option Share iTunes Library XML with other applications on."

I wonder the same, ultimately glad it's fixed as it was very annoying. Figured apple would be smarter and just have the box checked as a default right?

From apple: "iTunes Library.xml contains some (but not all) of the same information stored in the iTunes Library file. The purpose of the iTunes Library.xml file is to make your music and playlists available to other applications on your computer. If you delete the file, iTunes creates a new copy from the iTunes Library file."

Thanks worked perfectly and yes I have Plex installed.
