When you connect an i Phone or i Pad to a computer with i Tunes and an i OS software update is available, you will be notified with a pop-up that tells you a new version of i OS is available and asks if you want to update to the new version of i OS system software.Additionally, if you click on the “Check for Update” button in i Tunes when an i Phone, i Pad, or i Pod touch is connected, the same i OS software update process begins and the software will download and attempt to install.This was to prevent malware and viruses from making unauthorised changes to your computer without your knowledge.Whenever you install an application or program on your computer, the screen will dim and a small window will pop up asking "Do you want to allow this app to make changes to your PC?Of all of Apple’s software platforms, the one that you’re most likely to use on your computer, whether you have a Mac or a PC, seems to be i Tunes.It’s not only a useful place to manage the giant media library you probably still have, but it’s also an essential piece of software for managing any Apple devices you may own." to verify that you want to authorise an application to be installed.The i Tunes installer pops up with this window because it needs to install specific program files in a restricted folder on your computer ( on 64-bit machines) as well as some programs that will run in the background to monitor if you have plugged in an i Pad, i Pod or i Phone.
You might need to close i Tunes before proceeding in the installation process, so make sure you have saved everything on i Tunes, such as playlists and music downloads.
i Tunes has been around for a long time, in fact its first release was back in January 2001.
The program has evolved a lot since then and certain ways of using the program have also changed.
The process can be repeated the next time an update is accidentally starting to download, but it always requires quick action.
You must move quick because some software updates are quite small and with a fast internet connection the i OS update will quickly download and start trying to install.
