Ok guys, I'm officially confused about all this firmware. Right now I received a new firmware update with the date 11 feb 2014. The version actually installed in my surface 2 pro is 2.04.0450 (that should be the March 2014 version). How can windows update ask to me to install an older version? Someone has the same problem? I have to install it or is better hide and ignore it? Thanks to everyone who can light me up!!!!!!!
