如果要得到系統資訊或 WMI 資訊，網路上的介紹有一部分會提到 WMIC 指令，WMIC 是甚麼呢? WMIC 是一個 Windows 的命令列和腳本接口，簡化了使用 WMI 和透過 WMI 管理系統的功能，可以提供大量有關本機和遠端電腦的資訊。如果不想深入了解 WMI，如 WMI 的樹狀結構、命名空間與資料庫等複雜內容，用 WMIC 工具得到的系統資訊也已經很豐富了。下面就來介紹如何使用 WMIC。
Windows 中可以使用
步驟
>wmic /?
WMIC is deprecated.

由 Result 我們可以知道的事情有，Microsoft 的 WMIC Tool 目前是棄用狀態，但還是可以在 Windows 使用。
我們可以得到 WMIC 的 Switches 和 Aliases 清單，Switches 用來設定預設的 WMIC 環境。Aliases (別名) 協助 WMIC 執行存取 WMI 基礎結構，是獲取某些特定任務（如處理器、磁碟或網路管理）相關的 classes、 properties, 和 method 的友善集合名稱，使輸出格式更加簡單明瞭。 可以使用的 Aliases 從 ALIAS 到 WMISET，使用 wmic Alias 指令可得到 Alias 對應的資訊，如 wmi CPU、 wmi BIOS 等。
以 CPU 這個 Alias 為例，一步步了解如何使用 WMIC。
> wmic CPU /?
CPU - CPU management.
HINT: BNF for Alias usage.
(<alias> [WMIObject] | <alias> [<path where>] | [<alias>] <path where>) [<verb clause>].
USAGE:
CPU ASSOC [<format specifier>]
CPU CREATE <assign list>
CPU DELETE
CPU GET [<property list>] [<get switches>]
CPU LIST [<list format>] [<list switches>]
我們可以知道 CPU 這個 Alias 有 ASSOC、 CREATE、 DELETE、 GET、 LIST 這些指令可用，要取得資料當然是使用 GET。
> wmic CPU GET /?

GET [<property list>] [<get switches>]

The following GET switches are available:
/VALUE - Return value.
/ALL(default) - Return the data and metadata for the attribute.
/TRANSLATE:<table name> - Translate output via values from <table name>.
/EVERY:<interval> [/REPEAT:<repeat count>] - Returns value every (X interval) seconds, If /REPEAT specified the command is executed <repeat count> times.
/FORMAT:<format specifier> - Keyword/XSL filename to process the XML results.
NOTE: Order of /TRANSLATE and /FORMAT switches influences the appearance of output.
Case1: If /TRANSLATE precedes /FORMAT, then translation of results will be followed by formatting.
Case2: If /TRANSLATE succeeds /FORMAT, then translation of the formatted results will be done.
由 Property 這欄的內容，我們知道了 Alias CPU 可以得到那些資訊，接著就使用指令來得到資訊吧。

有些有資訊、有些沒有，所以我們知道雖然 WMI 有著一定的資訊架構，
但系統沒有提供給 WMI 就是沒有，甚至會不支援，使用上要注意。
