不久微软也公布了相关内容 ，其中关于默认值的部分值得关注:Recommended Defaults for Enabling/Disabling Virtualization Extensions. The default setting of this switch requires some thought. Consider the costs of disabling Intel Virtualization Technology/AMD Virtualization through a system firmware setting: If these facilities are disabled by default in system firmware， users would have to explicitly enable that support on each platform instance for legitimate uses， which would represent a significant challenge for enterprises that have thousands of machines and plan on using the hardware extensions. The cost of enabling virtualization hardware support through a manual system firmware setting would result in an increase in deployment time and cost. This cost can be mitigated through the use of various in-band and out-of-band mechanisms for remote management. Given the current usage model for the virtualization extensions， we believe that the following default settings are the right ones for system firmware: For systems that are destined for a server role ， enable the virtualization extensions. The threat of running malicious code as an administrator on servers is reduced through Windows Server policies and organizational best practices. For systems that are destined for a client role， disable the virtualization extensions. For systems that might be deployed in either a server or client role ， it would be prudent to disable the extensions by default. As always， the exception to any guideline is when a customer specifically indicates to a manufacturer that they do not want to follow that guideline.
cpu支持虚拟化技术。关键看主板是否支持了，进bios里面看下cpu configuration里是否有amd-v或secure virtual machine，改为enabled，再按 f10保存退出即可。虚拟化技术是集成指令来的，不需要打开的，直接用的。
IT之家 8 月 31 日消息 据 Windowslatest 报道，联想近日确认Windows 10 KB4566782 和 Lenovo BIOS 中的错误会导致 ThinkPad 笔记本电脑陷入蓝屏死机，官方提供了一种解决方法，似乎可以为用户解决该问题，但非联想用户在 8 月补丁之后也遇到了问题。
