iTunes is the application that Microsoft makes available to us in order to manage the content of our iPhone, iPad or iPod touch. This application is available for both Windows and macOS, although it is installed natively for the latter. Thanks to iTunes, we can copy images from our hard drive to the iPhone, iPad or iPod touch.
But also, we can copy music, ringtones, videos ... As technology evolves, the iPhone, iPad and iPod touch models require more modern computers and equipment to be able to manage the information they contain, so each new version of iTunes requires a few minimums in order to function.
Currently, at the time of writing this article, the oldest version of Windows compatible with iTunes is Windows 7, and from then on, so if you are looking for a version compatible with Windows XP, you will not find it directly on the Apple website, so you will have to search the Internet, to see if any website still has it at your service. But this does not mean that the iTunes 12.x version will not work in Windows XP as long as it is the 64-bit version, since it is the only one currently offered by Apple of iTunes for Windows.
If your computer doesn't have the 64-bit version of XP installed, don't bother trying to install it. If you want to test if the latest version of iTunes is compatible with Windows XP in its 64-bit version, you just have to download it from here, and try to install as long as your computer is an Intel or AMD at 1 GHz and with at least 512 MB of RAM, which is equivalent to an Intel Pentium D and a graphics card compatible with DirectX 9.0. In addition, the minimum resolution must be 1.024 x 768 and have a 16-bit sound card.
