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?

Customers who are experiencing difficulties restarting their systems after the
  installation of security update 2982791 should refer to the Known Issues 
section of Microsoft Knowledge Base Article 2982791.

Why was this bulletin revised on August 15, 2014?

Microsoft revised this bulletin to address known issues associated with 
installation of security update 2982791. Microsoft is investigating behavior 
associated with the installation of this update, and will update this bulletin

download links to the 2982791 security update. For instructions on how to 
uninstall this update, see Microsoft Knowledge Base Article 2982791.

I am running Windows 8.1, Windows Server 2012 R2, or Windows RT 8.1. Why am I
not being offered the 2982791 or the 2976897 updates?

To be offered any security updates on Windows RT 8.1, Windows 8.1, and Windows

For Windows 8.1, Windows Server 2012 R2, and Windows RT 8.1 are there any 
prerequisites for the 2982791 or the 2976897 updates?

Yes. Customers running Windows 8.1, Windows Server 2012 R2, or Windows RT 8.1
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.

There are multiple update packages available for Windows Vista, Windows Server
  2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, 
Windows RT, Windows 8.1, Windows Server 2012 R2, and Windows RT 8.1. Do I need
  to install all the updates listed in the Affected Software table for the 
software?

Yes. Customers should apply all updates offered for the software installed on
their systems.

Do I need to install these security updates in a particular sequence?

No. Multiple updates for one version of Microsoft Windows software can be 
applied in any sequence.

I am using an older release of the software discussed in this security 
bulletin. What should I do?

The affected software listed in this bulletin has been tested to determine 
which releases are affected. Other releases are past their support life cycle.
For more information about the product lifecycle, see the Microsoft Support 
Lifecycle website.
