I've been trying to use the following code to quickly display a computer's serial number through command prompt. Trying to use the powershell command because Microsoft will be getting rid of WMIC.

FOR /F "usebackq delims=" %%A IN ('powershell.exe -NoProfile -Command "Get-CimInstance Win32_BIOS | Select-Object -ExpandProperty SerialNumber"') DO (SET "serial=%%A")

ECHO %serial%

When run from the batch file the serial number that gets displayed to the screen is:

powershell.exe -NoProfile -Command "Get-CimInstance Win32_BIOS | Select-Object -ExpandProperty SerialNumber"

How can I make this work?

Just get rid of the quotes in SET:

FOR /F "usebackq delims=" %%A IN (`powershell.exe -NoProfile -Command "Get-CimInstance Win32_BIOS | Select-Object -ExpandProperty SerialNumber"`) DO SET serial=%%A

In plain Powershell it would be much simpler:

 Get-CimInstance Win32_BIOS | Select-Object -ExpandProperty SerialNumber | Set-Item -Path ENV:serial

Got it to work with the following:

SET "serial="

FOR /F "usebackq delims=" %%A IN (`powershell.exe -NoProfile -Command "Get-CimInstance Win32_BIOS | Select-Object -ExpandProperty SerialNumber"`) DO (SET serial=%%A)

ECHO %serial%
