Microsoft is currently working hard to fix hole in a 64-bit Windows 7 graphics display component which could potentially be exploited by those with nefarious motives, where it is able to crash the system or even take control of the computer by running code remotely. This vulnerability affects 64-bit versions of Windows 7 and Windows Server 2008 R2, and Itanium-based Windows Server 2008 R2, and Microsoft hopes to have a security update rolled out pretty soon to address the vulnerability once the testing phase is complete. What can you do on your part then? Well, just disable the Windows Aero desktop experience and you should be safe for the moment. As a reminder, always make sure your software is up to date with the latest patches and security fixes.
