what addin or applications do you have installed? The update does not cause
problems for most people so its likely a side effect of the interaction with
a third program that most people don't use.

It has the Business Contact Manager, that was on the installation. I let it
install in order to have a look, but I don't use it. That PC is my desktop,
so I run email there, but I mainly use the PC for photo editing.
