在 Windows 7 RTM 即将发布之际，Windows Virtual PC 迎来了 RC。Windows Virtual PC（WPC）更加成熟，从特性列表中，可以了解到 WPC 颗粒化的共享控制机制可以让用户设置那些资源可以用于交互共享访问。并且完全支持 Windows 7 的 Jump List 新特性，使我们能够快速的选择要启动的虚拟应用程序。而且 Windows XP Mode 的安装相比之前的 Beta 更加快速。对差分磁盘我们可以对其压缩以减小体积。此外，在安装完 WPC 首次运行时会运行学习向导，帮助用户了解和掌握 WPC 的操作。

        Windows Virtual PC RC 的改进还是非常明显的，面对貌似“苛刻”的硬件需求，除了功能以外，相信用户更关心的是：“我付出了相对高的硬件代价，那么最终的运行性能是否完全令人满意呢！？”（PS：其实现在买一个具有 VT 技术的 CPU，并不昂贵！gOxiA 刚买的 E5300 就支持 VT 和 EMT64 技术，而且目前的市场散装价格不过 430 元。）

        OK，还是来看看官方就 Windows Virtual PC RC 特性的总结列表。
