VT作为一款实体切削模拟验证软件，用来验证我们编程软件后处理出来NC程序的正确性。尤其在多轴程序验证方面应用广泛。然而在安装问题上，网友们会遇到一些问题，特别是安装在电脑里面，却无法打开，很是让人恼火。
Win7、win8.1已经停止更新，包括技术支持、软件和安全更新，微软都不再向系统提供。下一个将被放弃的版本是win10，已经在微软的计划范围内，微软宣布会陆续停止win10老版本的更新。据悉，3月份之后，Win10 20H2和21H2将不再有可选的、非安全预览版本。

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.
