After installing the latest update I was getting a MSVCR80.dll missing error when I start Windows and was unable to connect my iPhone 5. Appears there are plenty of bugs in the new update affecting Windows users so beware when prompted to update.
Apple forum was of help

I ended up having to
Go to Programs and Features and uninstall:
iTunes
Apple Application Support
Apple Mobile Device Support
Apple Software Update
Reboot. Download a fresh copy of iTunes
All working Ok now but a bit of a pain
Apple need to beta test a little more before releasing its updates.
