某个自动化的脚本，需要通过WMIC命令来读取网卡的speed信息，然而，有一台Windows Server 2019的实体机，这个命令却读不到网卡的speed信息。使用的命令如下：
wmic NIC where netenabled=true get speed,name,netconnectionid
尝试用WMIC命令直接修改，失败了。网上搜索了一番，也没有什么斩获。后来经过比对发现，这台机器跟其他机器的区别是，这台机器上开启了Hyper-V服务。
于是，禁用了Hyper-V之后，问题解决了，成功的获得了网卡的信息：
PS C:\Users\Administrator> wmic NIC where netenabled=true get speed,name,netconnectionid
Name NetConnectionID SpeedMellanox ConnectX-5 Ex Adapter SLOT 4 Port 1 100000000000
Mellanox ConnectX-5 Ex Adapter #2 SLOT 4 Port 2 100000000000
注意：
WMIC is deprecated as of Windows 10, version 21H1; and as of the 21H1 semi-annual channel release of Windows Server. This utility is superseded by Windows PowerShell for WMI; see Chapter 7 - Working with WMI.
This deprecation applies only to the WMIC utility. Windows Management Instrumentation (WMI) itself is not affected. Also see Windows 10 features we're no longer developing.
