Some of the Fonts not displaying properly since windows updates installed today. 12.12.12

I got calls from 3 of the DRAW users that some of the fonts are not displaying correctly since they have updated their Windows today. I have not yet connected my laptop to internet. Shall check it and try to identify the culprit update. Any light on this is appreciated.

Few fonts known for not displaying correctly since today

Diavlo_MEDIUM_II_37.otf and its family with light, black etc.
