Okay, just follow these easy to follow steps. First of all, right-click anywhere on your desktop to bring up a little menu and then click the properties menu.
Then click on Desktop. You can't miss it, the arrow is pointing to it.
Then click on Customize Desktop. Again, the arrow. But remember to follow them in order.
Then Click on Web.
And on this tab, if you click on the "New" button, you can basically put in the codes that you need for all the gamertags.
Get them from here. Remember the arrow.
Now if you were really eagle-eyed, you will have noticed the handy button to lock desktop items. Here it is again.
Basically, if you arange all your cards on the desktop as you like, if you tick that box, then you won't be able to accidentally resize, delete or select the cards on your desktop. They will basically be frozen in place which is really helpful. If you want to delete them, you have to do it from the above tab and uncheck the different addresses in that box.
And anytime you want to check the latest score, all you have to do is presh refresh.
It hasn't got an arrow this time.
