If you’re a stickler for customization when it comes to your devices, this news might upset you. Apparently the background designed for Windows 8 Metro is not customizable and the direct of communications, Chris Flores has a reason for this.
“Not only would a photo not stretch and scale as you add more tiles and groups and zoom in and out of the Start screen, it would also be covered up so much by the tiles that you’d never see it.”
While full-on customization isn’t possible, the OS will ship wit a theme picker page that will allow you to choose from 8 different styles and colors. While this is definitely a good start in the right direction, I can’t help but feel this restriction is something many people will complain about, regardless of whether or not Microsoft feels like the wallpaper you choose for your device won’t fit into the MetroUI.
This tired line of reasoning sounds like something that should be coming out of Tim Cook’s mouth, instead of something from someone at Microsoft. If you’re interested in knowing more about the features of MetroUI, check out this TechRadar post.
