For some reason, if you are not able to install iTunes on your Windows computer (10 or 11) and receive an error message something like this “One or more users on this computer have installed iTunes” then this video should explain the reason for it.

In most cases, the reason why you are getting this error is that iTunes has been already installed on your Computer via the Microsoft store. You can in fact continue to use the same iTunes or uninstall it and get a new one from the official iTunes store. Regardless, both iTunes work the same.
