In Windows 8.1 those settings are in the SkyDrive sync settings. It will sync your lock screen, desktop wallpaper, Metro screen background, user account picture, even your tile layout if you wish across multiply devices. If you reinstall and log back in with the same live ID it all gets refreshed back to what you had before.
Charms bar > settings > Change PC Settings > SkyDrive > Sync Settings
Thanks to all that contributed to this thread
Thank you alphanumeric on pointing out where to access these flags.
I didn't even know these feature existed without you enabling them. I didn't even know I had a skydrive folder in my user account to sync things in my outlook account.
Thanks again - great support on this forum.
One quick follow up question that I think someone else earlier asked (sort of),
Are we able to actually view what information MS stores on our accounts? I know we can view the things we intentionally stored like documents, videos and picture, but can we see misc things like what desktop background, personal preferences and things that are stored?
I don't see my background anywhere on skydrive.
