Update FAQ
Why was this bulletin revised on August 27, 2014? What happened to the
original 2982791 security update?
To address known issues with security update 2982791, Microsoft rereleased
MS14-045 to replace the 2982791 update with the 2993651 update for all
supported releases of Microsoft Windows. Microsoft expired update 2982791 on
August 15, 2014. All customers should apply the 2993651 update, which replaces
the expired 2982791 update. Microsoft strongly recommends that customers who
have not uninstalled the 2982791 update do so prior to applying the 2993651
update.
I already successfully installed the original 2982791 security update and am
not experiencing any difficulties. Should I apply the replacement update
(2993651) released on August 27, 2014?
Yes. All customers should apply the 2993651 update, which replaces the expired
2982791 update. Customers do not need to uninstall the expired 2982791 update
before applying the 2993651 update; however, Microsoft strongly recommends it.
Customers who do not remove the expired update will retain a listing for
2982791 under installed updates in Control Panel.
I uninstalled the original 2982791 security update. Should I apply the August
27, 2014 rereleased update (2993651)?
Yes. To be protected from CVE-2014-0318 and CVE-2014-1819, all customers
should apply the rereleased update (2993651), which replaces the expired
2982791 update.
What if I experienced difficulties restarting my system after installing
security update 2982791?

must first install the 2919355 update released in April, 2014 before
installing the 2982791 or the 2976897 updates. For more information about the
prerequisite update, see Microsoft Knowledge Base Article 2919355.

2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012,
