Windows：如果你运行的是64位版本的Windows，你现在可以下载一个支持64位的Chrome版本，它包括更好的性能、安全性和稳定性。

现在，64位版本可以在Chrome的Dev和Canary通道中使用，但是随着Chrome的快速发布周期，它很快就会进入Beta测试并稳定。谷歌称，64位版本有很多改进：

• Speed: 64-bit allows us to take advantage of the latest processor and compiler optimizati***, a more modern instruction set, and a calling convention that allows more function parameters to be passed quickly by registers. As a result, speed is improved, especially in graphics and multimedia content, where we see an average 25% improvement in performance.
• Security: With Chrome able to take advantage of the latest OS features such as High Entropy ASLR on Windows 8, security is improved on 64-bit platforms as well. Those extra bits also help us better defend against exploitation techniques such as JIT spraying, and improve the effectiveness of our existing security defense features like heap partitioning.
• Stability: Finally, we've observed a marked increase in stability for 64-bit Chrome over 32-bit Chrome. In particular, crash rates for the the renderer process (i.e. web content process) are almost half that of 32-bit Chrome.
