February's Patch Tuesday continues its tempestuous ways. Now there's word that one of the optional Office 2013 patches, KB 3114717, makes many installations of Word 2013 unusable. In addition, there are reports -- apparently related -- of lockups and slowdowns with Excel 2013 and Outlook 2013.
Posting yesterday on the Technet Office forum, Christoph von Wittich says:
When KB3114717 is installed typing in a .docx Document becomes nearly impossible and CPU load goes to 100% (.doc has no issues). This happens with Word 2013 only, Word 2016 is not affected. Tested on Windows 8.1 Enterprise, Windows 10 Enterprise 10240 and Windows 10 Enterprise 1511.
Further investigation shows that:
•The problem occurs with Word 2013 SP1 32-bit. (Many people prefer the 32-bit version of Word 2013 over the 64-bit because of historic stability questions.)
•It also appears on 64-bit Windows 7 SP1 and Server 2002 R2.
•The bug drives one processor core to 100 percent utilization, making it effectively impossible to edit a document.
•Running Word in safe mode doesn't help.
•There are reports that the problem occurs with both DOC and DOCX files.
•There are additional reports (still unconfirmed) that a similar problem occurs with Outlook.
