Microsoft has rushed to release an emergency windows patch for all versions of Windows OS yesterday. Latest windows patch covers the gaping and under attach security flaw in the way shortcuts are displayed by the operating system. Out of tradition, company releases patches once in a month, latest release shows the seriousness and importance of this patch to users who need to install this on their system asap.

The out-of-band update, rated “critical,” comes less than 20 days after the discovery of a sophisticated malware attack that combined the Windows zero-day flaw with security problems in SCADA systems and used stolen signed drivers to bypass security software.

Since then, it’s been used to install general-purpose malware from Zeus and other do-it-yourself crimeware kits used to siphon credit card numbers and other sensitive data from compromised computers. The Windows flaw resides in a shortcut feature that makes it easy to store commonly accessed files and folders on the operating-system desktop.

Windows users, who recently employed a stopgap FixIt published two weeks ago should roll back their machines using the “disable workaround” feature. Those who don’t follow this advice will find that icons fail to display properly, causing folders and files to appear white without any of the customary graphics.

Windows Users will most likely have to reboot their machines twice — once after uninstalling the workaround, and again after installing the update. Microsoft’s out-of-band bulletin is here
