There are several articles on this newly appearing today. Crosses all versions of Windows still supported, and apparently Outlook 2010 and 2013, though I don't know if others are involved. The Update in question is 3097877, which you can read about here. It's supposed to be a 'critical' update correcting some flaw that occurs when HTML language is used in an email, hence the connection to Outlook.
Reddit report is the most detailed and varied, here. Lots of specific data there, search also on 'touchscreen', as its failure might be linked only to devices with touchscreens.
Most of the reports say that Windows balks or BSoD's, or merely Outlook does that. So I'm not sure if my posting this is in the right place. Please move it to the right place, if you prefer. Thank you for your time!
