Firstly, Please make sure you used thelatest version of itunes. You can go to apple.com to check the latestinformation. Secondly, make sure you have the right download of iTunes (32-bitor 64-bit),
if you have download theright one for your system, that could cause driver issues which is the numberone cause of blue screens. If that still don’t work, you can try a 3ed-partytool like iphone/ ipad transfer
ipad transfer, if the 3ed-party tool still don’t work, well,there’s no other way but you have to get rid of win7 system…
