We have noticed that since this month’s updates have installed Word 2016 is crashing when clicking on the File menu when certain (not all) documents are open.
Our initial investigations have revealed that if we open a document that works (a fresh .docx or any .doc) and while Word is still open try and open a problematic .docx it works. If we try and open a problematic .docx with Word closed first, accessing the
File menu causes Word to crash. What’s interesting is that it doesn’t seem to be all .docx files, only certain ones, but for the moment we haven’t identified any commonality between the problem files, in fact most are simple documents with no embedded pictures,
macros etc.
Removing the Update for Word 2016 (KB3178720) resolves the issue. However, if we install this update on its own on a VM, it does not cause the issue, so it appears to be caused by a combination of updates released this month rather than just this particular
update, but removing this one update resolves the problem.
