How to Adjust Your Windows 8.1 Store Accounts and Preferences
In the Windows Store app in Windows 8.1, you can adjust a limited number of settings for your accounts and preferences. To make these adjustments, begin by tapping or clicking the Windows Store app from the Metro Start screen.
Swipe from the right to bring up the Charms bar or hover your mouse in the upper-right corner. Tap or click the Settings charm.
You see the Settings pane shown.
Choose Your Account.
Windows shows you the Windows Store Your Account page.
Change User lets you switch to a different Microsoft account. That’s useful if you’re using an anonymous Microsoft account but want to buy something in the Windows Store — switch your account over, buy whatever you want, download it, and then switch back to your anonymous account.
Payment and Billing Info if you don’t already have a credit card associated with your current Microsoft account, you can add it here. Having Windows ask for your password when buying an app makes it more difficult for your three-year-old to run up a $1,000 bill.
Your PCs shows the five PCs that are permitted to share the apps that you buy. You can remove a PC here.
Swipe from the right to bring up the Charms bar or hover your mouse in the upper-right corner. Tap or click the Settings charm. Choose Preferences.
Windows shows you the Store Preferences page, which makes it easier to find apps that support limited accessibility; it also lets you extend your searches to other languages.
Swipe from the right to bring up the Charms bar or hover your mouse in the upper-right corner. Tap or click the Settings charm. Choose App Updates.
Windows shows you the Store App Updates page.
In this case, automatic means that Windows downloads the updates, but doesn’t install them until you give your permission.
Unlike Windows updates, app updates are relatively innocuous, as long as you’re only updating apps.
Unfortunately, this setting is currently being used to grant permission to update parts of Windows itself — more than just updating the tiled Metro apps. As long as Windows updates go through the Windows Store, turn off this switch and watch for a number on the Windows Store tile. Then carefully decide if you want to update.
When you’re done, tap the Windows button on your tablet or click the lower-left corner to go back to the Start screen.
