While there are several free apps and games at the Windows Store, eventually you're going to want to buy something. When you buy an app, game, movie, music, or TV show from the Windows Store, you'll need to add a payment method to your account. We'll show you how.
1. Open the Store and tap the user icon on top. Tap or click payment options. This opens the web browser where you can add or remove payment options.
2. To get started, tap or click Add payment option. Enter your credit card or PayPal information, and then click or tap Next.
3. To remove a payment option, tap or click an existing card and then select remove. A confirmation message pops up, so you can double-check if you really want to remove it.
That's it! Next time you try to buy something from the Store in Windows 10, you can use your preferred method of payment. You can also change or add a payment method from the purchase screen, but you can't remove. Tap or click change under the payment method and then select a different card or add a new payment method.
