打开Win11，开机后在CMD里 我输入wmic memphysical get maxcapacity查看，结果显示

我的台式电脑原来是Win 10，在CMD里 我输入wmic memphysical get maxcapacity查看最大RAM，输出了Maxcapacity. 在我把它升级到了Win 11后，就正常关机了。一个月后今天我打开Win11，开机后在CMD里 我输入wmic memphysical get maxcapacity查看，结果显示 Invalid NameSpace. 这是怎么回事？我打开了Windows Management Service, 还是显示 Invalid NameSpace. 这一个月，我的电脑一直没有开机用过。

这是Google的答案：

WMIC is the Windows Management Instrumentation Command-line utility, a legacy command-line tool used to interact with Windows Management Instrumentation (WMI) to manage and query computer system information, such as hardware and software details, but it is being phased out and removed from modern Windows versions. It was converted to a Feature on Demand (FoD) in Windows 11 and is being disabled by default, with plans for complete removal after the Windows 11 25H2 release.
