Welcome to the July 2015 patch overview that reviews all security and non-security patches that Microsoft released this month for Microsoft Windows and other company products.
This is the last Patch Tuesday before the release of Microsoft's new operating system Windows 10.
The guide starts with an executive summary that provides you with a quick overview of the most important information.
It is then followed by information detailing which Microsoft products and versions are affected by security patches, and then the list of security patches and security advisories.
Afterwards, we list non-security patches that may be of interest and how to download and deploy the updates.
Operating System Distribution
Windows Vista is affected by two critical bulletins while all other client operating systems are only affected by one. The bulletin that affects Vista but no other client operating system is MS15-066 which patches vulnerabilities in the VBScript Scripting Engine.
The server side shows a similar picture, only that Server 2003 and 2008 are affected by the same vulnerability while newer Server versions are not.

Security Advisories and updates
Non-security related updates
How to download and install the July 2015 security updates
Updates are provided via Windows Update if automatic updates are enabled. Updates are not picked up in real-time by Windows which is why you may want to run a manual check for updates to download and deploy them as soon as possible.
Windows users who don't want to download updates automatically find them listed on Microsoft's Download Center as well.
There they are offered as individual downloads and as a monthly security ISO image.
Last but not least, several third-party programs exist that you can use to download all patches in one operation without using Windows Update.
