And updated iTunes and I hate it. It is on my wife's windows laptop.
How can I uninstall the new version 11 and install the old one back without losing any of songs.

Just say no to Apple....
Do yourself a great big favor, and use a different player.


This is what I use, great for large collections.
MediaMonkey » Free Media Jukebox, Music Manager, CD Ripper & Converter
Keeps track of thousands of titles, across many drives.
Also plays nearly every format you could ask for.
Converts on the fly, rips in a variety of formats.
Will write to iOS 6 devices. Not sure if they have broken 7 (or whatever the new one is)

Musicbee is pretty good as well.

Do you need it in order to sync with a Crapple SpyPhone? If not, delete it, install a real music player like MediaMonkey. There are plenty of um ... alternative ... download services.

iTunes on Windows has always been a slow, sub-par, buggy pain in the gluteus. Gee, wonder why -- maybe Apple wants people to buy THEIR hardware

Edit: haha, cmbdiesel said it first, and more politely than I did!
