I don't disagree, i think their QA had been significant reduced, but at the same time there is also the aspect, of their own creation, that there are a lot more variables then there once were. So many OSes, versions of Office, msi, ctr, bitnesses, and so
many more elements i doubt there is a way to properly test for them all. And we haven't even gotten into hardware, drivers, ...
Yes, i think much of the blame does fall on MS' shoulders, but at the same time you have to somewhat feel bad for them. I know the Address Dev Team doesn't want to release flawed updates. They truly care about the product!!! It's just too bad for everyone
involved.
I also hope, and believe, that once they identify a new issue like the current one, that they will adjust the testing to avoid the oversight from happening with future updates.
I know it's being investigated, but it's tough to figure out because it isn't widespread and only impacting a subset of users.
Time will tell.
