While purchasing an app, game, movie or any other thing from Windows Store on a Windows 10 using a credit card, the credit card information is automatically saved on your Microsoft account so that the user don’t need to enter the credit card number or any other information next time the purchase is made.
You still need to enter the password every time you make a purchase so even if someone has access to your PC they won’t be able to make the purchase as long as they don’t have the password.
So you don’t need to worry as long as you’re the one only one who knows the password or unless you have configured Windows 10 now to ask password while purchasing apps, it’s wise to delete your credit card information after completing a purchase to stop them from getting into the wrong hands.
Since there are many ways and tools to recover your password so anyone who has little knowledge about computers will be able to gain access and purchase items without your knowledge.
