Can’t sync my Nokia Lumia 920, Windows Phone 8, to a PC which runs under Windows 7 or Windows 8? All
USB-connection drivers, Nokia PC Suite,
Windows Phone app
 or Nokia Music Player were installed.
All you have to do is to create a Nokia account. You can connect to Nokia with an created and activated
Facebook account. After creating a Nokia
account the connection
with a PC running under Window 7 or Window 8 is persistent applied.
Maybe it helps to switch the handy power off and on respectively with restart.
The running operation system doesn’t matter. I had installed Windows 7 and Windows 8 and both times
it doesn’t work and after created a Nokia
account on my Lumia
920 it works fine on both Windows platforms.

The Windows Phone is now shown in the File Explorer, also as usable with synchronation tools like Nokia
Musik Player or others mention above.
