Hi All,
Microsoft initially released the KB3097877 on 10th November which was defective.
Have a look at the Revisions Section: Microsoft Security Bulletin MS15-115 - Critical
""V1.0 (November 10, 2015): Bulletin published.
•V2.0 (November 12, 2015): Bulletin revised to inform customers that the 3097877 update for Windows 7 and Windows Server 2008 R2 has been rereleased to correct a problem with the original update that could cause some applications to quit unexpectedly. Customers who have already successfully installed the update on Windows 7 or Windows Server 2008 R2 systems should reinstall the update."
They have released the fixed version on 12th November and the issue is not seen with it.
Hope it helps!
Regards,
Adil Raj
