Microsoft has four more bulletins, otherwise known as updates, to apply to computers this July as part of the company's unofficial tradition of releasing updates on the second Tuesday of the month. Overall there are 22 vulnerabilities, with the majority of them related for Microsoft's Windows operating system. There is also an important update bulletin available for the company's Office software suite.

The updates, which are due to come out on Tuesday 12th July 2011, will be automatically installed via Windows Update if users have the functionality turned on. Those who do not will need to make sure they manually update, given that the vulnerabilities include remote code execution and elevation of privileges. Below is an overview of all affected components in the update:

- Microsoft Windows OS (XP, Server 2003, Vista, Server 2008 (& R2), 7)
- Microsoft Office (2003)

Compared to the set of updates from last month's: http://www.microsoft.com/technet/security/bulletin/ms11-jul.mspx , July's does not contain as many bulletins. However as we observed in June, once information has been posted about the vulnerability, hackers are quick utilise the loopholes and damage unpatched machines. Microsoft has a page in which computer users may view more details on the updates: http://www.microsoft.com/technet/security/bulletin/ms11-jul.mspx
There are three updates among the four that will require a restart and this is applicable to both 32-bit and 64-bit versions of operating system.
