Windows XP users are no longer able to login to their iTunes account and in some cases can't access previously purchased movies and TV shows. Users report that they are no longer able to connect to their iTunes account and receive various error messages such as error 0x80090326, error -50 or simply an "unknown error". The 0x80090326 error indicates there is an issue in establishing an security connection.
The problem affects Windows XP users up to the current version of iTunes 12.1.2, which Apple offers for users on Windows XP SP3. It's appears that iTunes can't establish a mandatory secure connection with the iTunes Store on the unsupported and outdated Windows XP operating system.
Both Microsoft and Apple have not commented on the issue and so far the only solution appears to switch to another operating system.
The failure not only makes it impossible to purchase new content from the iTunes Store, but also causes problem when users want to watch earlier purchased movies or TV series. Users that purchased a season pass for a series can't watch any new episodes anymore. It's also no longer possible to authorize the PC for iTunes which makes it impossible to play DRM protected content.
