With only a small percentage of Windows users having upgraded to Windows 8, I suspect there are quite a few looking for a sync/phone management client for their new Windows Phone 8 phone to use in Windows 7.
Microsoft has now released an app which will work on both Windows 7 and the desktop mode of Windows 8.
The Windows Phone app for Windows desktop makes it easy to:
Sync music, photos, movies, TV shows, and podcasts from your existing Apple iTunes library or your Windows Libraries to your Windows Phone 8.*
Automatically import pictures and videos you’ve taken with your phone to your PC.
Find songs that will work as ringtones and add them to your phone.
Find the download at WindowsPhone.com here.
