64-Bit Version of Chrome for Windows 7 and 8 in Beta Channel
 

If you already run the Beta version of Google's Chrome browser and also run a 64 bit OS, there is a good chance that you have already been upgraded to the 64 bit version (37.0.2062.58) that was released on Wednesday. If not, you can update from within Chrome or go straight to the Chrome Beta page for a download. 64-bit Chrome should be faster, especially in graphics and multimedia content, and more secure since it can take advantage of Windows 8's built-in anti-exploit technology.
