NOWHERE however can I find a DEFINITIVE list of the KB#'s of the updates that caused the problems. I feel MS ought to share that list. From what I'm reading, this issue started back in November 2018 where Japanese users were affected first.
It all has to do with how the Japanese define their years.
I have some updates that are related to the Japanese calendar thing but they may be healthy cause they came out more recently. I am only going by the list above but there is a list here at this link below but that doesn't mean they all caused problems. It's
just the list of Office 2010 updates since this year.
https://support.microsoft.com/en-us/help/4488446/february-2019-updates-for-microsoft-office
And in this list it shows KB4462174 as Feb 12th which seems odd since this Japanese calendar issue was discovered back in Nov '18. All very confusing...
MS just really needs to release a list of the KB's that have issues and provide the exact KB #.
