If you're using Office 2013 ProPlus and/or Office 2013 Click-to-Run, and you applied the April updates, you may have noticed that both Lync 2013 (also know as Skype for Business) and/or Outlook 2013 have been crashing more frequently than usual. Specifically, those who have KB 3114941 installed, and those running Office 2013 CtR 15.0.4815.1001 are seeing crashes with error code 0xc0000005.

Microsoft has details of the problem in KB 3158521. The crashes generate this kind of entry in your Application event log:

Microsoft admitted to the problem yesterday and provided detailed instructions on how to roll back the bad April build to the less-buggy March build 15.0.4805.1003. For those running the "MSI version" -- the old-fashioned version of Office 2013 without Click-to-Run -- uninstalling KB 3114941 is relatively painless.

Rolling back a Click-to-Run patch, though, is not for the timid to undertake. However it's becoming a more common exercise -- particularly with the Feb. 16 version of Office 2016 Click-to-Run deleting POP3 email; the Word, Excel, and Outlook freeze in the Feb. 9 Office 2013 Click-to-Run; and the Word template renaming problem in the Dec. 11, 2015, Office 365 Click-to-Run.

By my reckoning, this is the fourth Office Click-to-Run recall in a little more than four months.
