WMIC

---

WMIC (Windows Management Instrumentation Command-Line) is a command line tool that lets you obtain information and perform various functions on the local Windows computer or remote Windows computer.

To run WMIC simply open a command prompt (you will need to use an elevated command prompt for some actions) and then type "wmic":

You can then enter WMIC commands.

Alternatively you can enter a WMIC command directly from the command prompt by appending the command to the wmic line:

The following is a list of WMIC commands that I have found useful, it is not comprehensive:

diskdrive get status

Show the SMART status of each disk drive. Anything other than "OK" indicates a problem with the drive. Be aware that drives can fail without SMART indicating a problem.

List installed software

product get name

Be aware that this may not return immediately.

To look for software with a name like (say ".. Apple ..") use:

product where "name like '%Apple%'"

List printers

printer list status

List running processes

process list
will list the application being run by each process (only).

process list brief
shows a short list of properties.

process list full
shows about everything there is to know about each running process.

process list /?
will show what information is available about each process. Then to get specific bits of information:
process list get Name, Handle, Status [, some-other]

Run a WMIC command remotely on another computer

Put /node:computer at the front of the command. For example:
/node:consult2 printer list status
will list the status of each printer on the remote computer called 'consult2'.

Send output to a file

use /output:file-name and /format:format before the desired command, for example:
/output:c:\temp\printers.csv printer list status /format:CSV
The message "Invalid file name." seems to indicate that WMIC lacks permission to write to that file. Common format specifiers are CSV (comma separated value) and HTABLE (HTML table).

Show cpu information

cpu
shows basic information. To see what information is available:
cpu /?
then to retrieve that information:
cpu get name, caption, maxclockspeed [, etc]

Show operating system

os

Terminate a process

To terminate a known named program:

process where name="program.exe" call terminate

Uninstall an application

product where name="product-name" call uninstall

You will be prompted to confirm the uninstall. To avoid the confirmation add the flag /nointeractive, so:

product where name="product-name" call uninstall /nointeractive

Be aware that it there may be a pause before it confirms or uninstalls the application.

To uninstall the same application from a list of computers:

/failfast:on /node:comp1, comp2 product where name="product-name" call uninstall /nointeractive

The switch /fastfail:on means that it won't hang waiting if a machine isn't responding (i.e. not available). To read the list of computers from a file:

/failfast:on /node:@list.txt product where name="product-name" call uninstall /nointeractive
