I would be interested to know what ms say. This is the first time I've had this kind of trouble with an update and the forum has been helpful in getting some generic help and also to see that many of us have had this problem.
What does surprise me though (even though all big companies behave in the same way) is that after it has become obvious that there is a problem with the update, the silence is deafening as the generic help comes to an end and there is no statement on the subject from the powers that be.
Even an admission that certain users are having an issue would be a start.
