How to Edit a Contact in the Windows 8.1 Metro People App
If you want to change the information associated with a Metro People person — a contact — in Windows 8.1's Metro People app, here’s how to do it:
Inside Metro People, tap or click a contact’s tile.
The contact details appear.
Swipe from the top or bottom or right-click the desktop to bring up the App bar at the bottom. On the right, tap or click the Edit icon.
The Edit Info pane appears.
Change the information you want to change.
Tap or click the Save icon. (It’s the one that looks like a 3.5-inch floppy disk in the upper-right corner. What? You’ve never seen a 3.5-inch floppy disk?)
If your contact suddenly disappears, there’s a reason why! If you changed the name, and the new name matches the name of a contact that’s already in your People list, Metro People consolidates the two contacts, throws away the picture for one of them, and presents you with the merged result.
A word to the wise: If People threw away one of your contacts, it’d be a very good idea to look at the details of the surviving contact and make sure they’re accurate.
