WMIC.exe

The WMI Commandline Utility for interacting with WMI.
WMIC.exe comes with large amount of convenient default aliases for WMI objects.
With Windows 10, version 21H1 and the 21H1 General Availability Channel release of Windows Server, the WMIC tool (but not WMI itself) is deprecated and superseded by Windows PowerShell for WMI.
The recommendation is to use the cmdlets of the CimCmdlets module: 
PS C:\> (get-command -module CimCmdlets).name

Invoking WMIC.exe

WMIC.exe is a command line tool. It is expected to be invoked like one of the following variants 
wmic
wmic global-switches
wmic command
wmic global-switches command
If command is not specfied, WMIC.exe is started in interactive mode.

/NAMESPACE Path for the namespace the alias operate against.

Querying information

A basic usage of WMIC.exe to query processes and their process ids: 
wmic process get processId,name
The where option allows to limit the result set: 
wmic process where "name='cmd.exe'" get parentProcessId,ProcessId

Meta information about WMIC

WMIC.exe can be used to query about WMI itself: 
C:\> wmic wmiset get DatabaseDirectory,EnableEvents,InstallationDirectory,LoggingDirectory,LoggingLevel,MaxLogFileSize
DatabaseDirectory                    EnableEvents  InstallationDirectory     LoggingDirectory                LoggingLevel  MaxLogFileSize
C:\windows\system32\wbem\repository  TRUE          C:\windows\system32\wbem  C:\windows\system32\wbem\Logs\  0             65536

Installed programs

The following query takes quite some time: 
wmic product get name,version
See also HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

Calling methods

Some classes provide methods that can be called. These can be queried like so 
wmic process call /?
This reveals, among others, that a process can be created. The first argument is the process, the second the directory in which the process is started: 
wmic process call create "cmd /k", %temp%

/format:list

With /format:list, an output that is too wide to be displayed in the console's width can be put in a list: 
wmic computersystem get /format:list

See also

wmic can be used to determine if Windows is running in 32 or 64 bit envorinment and or for querying user accounts.
