Q. In Windows 10, how do you make the screen and window backgrounds black instead of white?

A. Windows 10 includes a “dark” theme that flips the backgrounds of some apps from white to black. The operating system also has a high-contrast mode available in the Ease of Access settings that inverts the white background with black, while also changing the colours of buttons and menus to make them stand out against the dark background.

You can get to either option by pressing the Windows and I keys to open the Settings area, or by going to the Start menu and selecting the gear-shaped Settings icon. In Settings, choose Personalization and then Colours. In the Choose Your App Mode area toward the bottom of the window, select Dark; you can pick a custom accent colour for your windows here, too.

The dark theme works with several Windows 10 apps, but does not give everything a black backdrop. For example, the File Explorer and browser windows keep their white backgrounds. Some versions of Microsoft Office have their own dark themes, too, as does the Edge browser. Other browsers have similar add-ons; Google offers its own High Contrast extension for its Chrome browser.

For a more universal system switch from white to black, click the High Contrast Settings link under the app mode options in the Personalization box, or click the Ease of Access icon in the main Settings area. In the Ease of Access box, select High Contrast and choose a colour combination that suits you from the drop-down menu.

You can turn off or adjust either the dark theme or the high-contrast mode by returning to Settings.

Apple includes its own contrast and colour settings for the Mac in the System Preferences. To make adjustments, open the System Preferences icon in the desktop dock, click the Accessibility icon and choose Display.

Updating billing aata for Apple purchases

Q. How do I change the billing information for iPad app purchases?

A. You can update your credit card number, address or other details about the way you pay for your iTunes and App Store downloads by opening the Settings icon from the iPad’s home screen and selecting iTunes & App Store. In the box that pops up, tap View Apple ID and sign in, if prompted.

On the Apple ID screen, select Payment Information from the list, and on the next screen, make the changes you wish. Apple notes that if you are using its Family Sharing feature to corral all purchases made by members of a designated family group, only the user previously deemed the “organiser” can change the payment information.

If you are having trouble trying to remove a linked credit card from your account by switching to None as a billing option, make sure you have no outstanding charges with the iTunes or App Stores — or subscriptions that automatically renew and bill that credit card.

You can also change your Apple billing information from your Windows PC or Mac computer. To get to your settings from the desktop, open the iTunes program, go to the Account menu and select View My Account. Sign in with your account password (or click the View Account button if you are already signed in) and on the account settings screen, click the Edit button next to payment type to make your changes.

The process for changing billing information is similar for other companies that keep your electronic payment method on file — like Google, Amazon, Microsoft and apps that offer purchases or subscriptions. Simply find the account settings area, log in and locate the section for payment details. Just make sure you are on a secure network connection when you do.
