This topic appears to have dried up !
My situation was and still is --- WLM12 still working fine on Win 8.1 64bit.
Due to all reported problems, I did not download the update as per Microsoft email.
Microsoft knowledge article shows the KB as being at issue 2 but comments it is still subject to problems which are being investigated.
I contacted Microsoft using outlook.uservoice as mentioned in link in above post, asking when all issues with KB would be resolved. Received reply from Microsoft support engineer asking me to send screen shots of my problem --- he hadn't really read or understood the issue. On 7th January I sent him links to knowledge articles , forum posts etc but have not received acknowledgement or reply!
I have noted that Microsoft are now pushing the KB as an optional update via Windows Update although the knowledge article still states that it has potential problems !!
I have "hidden" the update for now as I don't want to introduce problems with WLM [my Outlook account has not yet been updated]
Does anybody know what is happening? Is the KB still lethal? Are Microsoft working on a fix?
As a non techy, simple user, I am left bewildered by this saga ---- ADVICE PLEASE
