Hello. Today I have a little plight with my iOS 9.0.1 iPhone 4S! To my understanding, I cannot back it up with my normal iTunes version (11.4)! I would not like to update iTunes (if possible) because, iTunes 12 is more frustrating than 11.4! So, i'm trying to think of a alternative. Normally (If I still had my Windows 7PC working [It's dead]), i'd run iTunes 12 on a 8.1 Duel boot (in that partition) however, I recently got a Windows 8.1 PC [Alienware 13t] and, it's a waste of a product key to duel boot 2 versions of Windows 8.1! At this point, I have 3 options. First, is it possible to install iTunes 11.4 on my Windows XP Virtual Box VM (It's legally set up (I used a currently unused product key that I had sitting around collecting dust on a laptop that no longer works and, I got it straight from Microsoft via Windows 7 Pro/Ultimate Virtual Machine file!) and, transfer all of my normal backups over to Windows XP and then update the 8.1 partition to iTunes 12.x? Second, do you think I should run in my Virtual-box VM iTunes 12 and, leave the already backed up files in the host partition running iTunes 11.4? Third and finally, should I leave my iTunes 11.4 data in the 8.1 partition and, set up my computer to run Windows 10 TP (alongside Windows 8.1 in a duel boot configuration)? Thank you for your help with this plight!
