Microsoft is about to release this month's security updates and patches for Windows client and server operating systems.
A total of eight bulletins are released this month. Three of the bulletins have received a critical severity rating, the highest possible rating. The remaining five bulletins received a rating of important, the second highest rating.
The eight bulletins patch a total of 19 different vulnerabilities in Microsoft products.
As far as the affected software is concerned, six of the bulletins address issues in Microsoft Windows, and the remaining two vulnerabilities in Microsoft Office.
You find detailed information about the bulletins below. This includes the operating system and Office distribution, deployment suggestions, links to each bulletin to look up additional information, information about non-security updates that were released since the last Patch Day, and finally instructions on how to download those updates to your PC.
Operating System Distribution
The following list displays the bulletin distribution for each client and server operating system that Microsoft is supporting right now.
On the client side, Windows RT takes the crown once again with the least amount of vulnerabilities, followed by Windows 7 and earlier versions of Windows. Windows 8 and Windows 8.1 are affected more than any other client operating system this time.
On the server side of things, all Windows Server versions are affected in the same way by this month's security bulletins.
Office 2003 is only affected by one bulletin rated important, while all newer versions of Office are affected by an additional bulletin.
Microsoft releases a deployment guide on each Patch Day that offers suggestions for administrators and individual users about the order of deployment of the released Windows updates.
Priorities are assigned to each bulletin using several factors including a bulletins severity rating, whether it is exploited in the wild, and other factors.
While this may not be an issue at all on individual systems, as patches can be installed in a heartbeat on them, companies who do testing before patches are applied may use the information to test and deploy patches in optimal order using the guide.

How to download and install the November 2013 security updates
The patches are already available via Windows Update. Most users should receive them via the built-in Windows updating system automatically. Some, who may have configured it to only download patches or do nothing can download them instead from other sources including Microsoft's Download Center.
The option is the most viable for users who want to test the patches before they are deployed on live systems. It can also help save bandwidth considering that updates need to be downloaded only once for deployment, instead of individually for each computer system that needs patching.
These updates can also be downloaded via third party programs that enable you to download all Windows Updates to your system.
The Microsoft Security Bulletin Summary for this month is available here. All bulletins are described here in an overview, and with links that you can follow for additional information.
